Transmitter (AURI-TX2N / AURI-TX2N-D)

The TX2N Transmitter is the heart of an Auri system, providing long range, low latency Auracast broadcast audio.

A pair of balanced switchable mic/line level inputs or an optional integrated two channel Dante interface allow a single stereo or two mono audio sources to be routed in a variety of ways to one or two broadcasts.

For a full description of features and configurations see the Auri Manager section of the handbook.

Unpacking

Unpack all contents from the box:

1x AURI-TX2N or AURI-TX2N-D Transmitter

1x Universal mounting bracket

3x Euroblock connectors

1x 1.8 m (6 ft) Cat6 cable

1x Quick Start Guide and Safety Data Sheet

Installation

Requirements

A Phillips head screwdriver is required for the captive retaining screw on the mounting bracket.

Fixtures and fittings such as electrical back boxes, screws and wall plugs will be needed, dependant on the install location.

A power supply is not included, if PoE is not available then a USB-C supply capable of delivering at least 500mA will be required.

Initial Setup

Remove the mounting bracket from the Transmitter, to do this you may need to loosen the retaining screw, then firmly slide the bracket away from the Transmitter.

Before installation it is recommended to do some basic setup of the Transmitter to ensure it is operating as required.

By default the Transmitter will be set with both inputs at line level, with nominal gain and AGC enabled. The two inputs will be summed into a single 24 kHz mono broadcast, named “Auri [serial]-1”.

Apply power (USB-C or PoE), plug a line level audio source in to one of the inputs and confirm that the broadcast can be picked up by an Auri Receiver or Auracast enabled device.

Locating the Transmitter

Determine a suitable installation location for the Auri Transmitter. This should be chosen to ensure good coverage of the intended listening area for a range of different receiving devices.

Transmitters should be installed at a height of 6 to 10 feet (1.8 to 3 metres) on a wall or ceiling and the Auri logo must always be facing into the room. Where users may face in multiple directions the Transmitter should be placed central to the coverage area. If all users will be facing in the same direction, such as in an auditorium, it is recommended to locate Transmitters in front of the users so that the Receivers have good line of sight to the Transmitter.

When multiple Transmitters are used for larger coverage areas they should be spaced with an overlap of approximately 20% on the coverage for the least sensitive receiving device that is to be used in the space.

The Transmitter range will be affected by the sensitivity of the receiving device, different building environments and the amount of other devices operating in the same frequency band. In larger or more complex spaces it is advisable to carry out a site test to confirm best placement and number of transmitters needed for full coverage.

Range will be decreased when Receivers are covered or obstructed, for instance a single earbud or hearing aid will have much greater range with line of sight to the Transmitter, for this reason in larger spaces at least two Transmitters will provide much greater range and consistency of coverage.

Cabling

Once the install location has been determined, make sure there is a cable route established and run the required cables. As a minimum power (USB-C or PoE) and at least one source of audio (balanced mic/line or Dante) are required. A permanent network connection is recommended for configuration and ongoing management.

Installing the Bracket

The mounting bracket supports a range of standard UK, EU and US electrical boxes, VESA 75 or direct mounting to a wall or ceiling. A minimum of two screws should be used to secure the bracket.

Rear or top cable entry is possible, depending on your install location.

Note that the bracket must be installed such that the Transmitter is facing into the room as coverage to the rear of the Transmitter is much lower.

With the bracket installed and cables terminated, hold the Transmitter close to the bracket and plug in the cables, a set of cable tie posts are provided to secure cabling and add strain relief.

Align the Transmitter below the bracket and push it upwards until you hear a click. The cable tray cover should be located in small slots at either corner.

Tighten the retaining screw at the top of the bracket. 

Configuring the Transmitter

With the final audio sources being connected, ensure there are signals representative of the intended use of the Transmitter, such as someone speaking into a microphone, or AV content being played.

As a minimum it is recommended to review the audio input mode and levels and to rename the broadcast, the Auri Manager software is required for configuration of the Transmitter. See the Auri Manager section of the handbook, and “Minimum Transmitter Setup” for more information.

The Transmitter output power should be adjusted to suit the install environment, in smaller spaces the Transmit Power should be reduced to avoid excessive signal being broadcast into adjacent areas. Where there are lots of Auracast systems operating in close proximity careful management of output power will result in better performance and a cleaner experience for the end users. Coverage should be validated in normal use of the space to ensure the Transmit Power is set appropriately for when the space is fully occupied.

Auri Manager

The Auri Manager software allows discovery and configuration of all Auri Transmitters, docks and docked Receivers over the network.

It can be downloaded from the Microsoft store, search for “Auri Manager” or use this link https://www.microsoft.com/store/productId/9NRJLR0V9QXH

Installation Requirements

The software should be installed on a Windows 10 or 11 PC with at least 300MB free space.

The PC running the application must be connected to the same network as the devices to be controlled, and in the same subnet. A “link-local” setup is supported, where a single ethernet cable between the PC and the Transmitter or dock allows each device to automatically negotiate a compatible IP address with no wider network infrastructure or DHCP server needed.

Discovery uses mDNS and communication relies on UDP within the ephemeral port range, there must be no firewall settings in place that restrict this traffic.

Quick Start – Minimum Transmitter Setup

  1. Install the software.
  2. Connect a network cable between the PC and the Transmitter.
  3. Connect the intended audio inputs.

4. Power on the Transmitter (with PoE or USB-C).

5. Launch the software.

6. On the Devices page, identify the Transmitter you want to configure – this will be named “Auri-TX2N(-D)-SerialNumber”. If no Transmitter is shown, wait a short while, in a link-local configuration the Transmitter can take up to 2 minutes to obtain an IP address. New devices should be shown automatically, if not click the Refresh button to manually rescan. If the device still isn’t shown a firewall exception may be needed, see the Troubleshooting section for more information.

7. Click on the Transmitter name, in the dialog enter the username and password you would like to use to manage your devices, confirm the password and click Next.

8. In the next dialog enter the default username and password for your device, each device has a unique password, the defaults are printed on a label on the rear of the Transmitter.

9. On the Inputs page, select the right microphone or line mode for each input and enable phantom power if needed.

10. With audio signals playing or someone speaking into the microphone, set a suitable input gain, such that the stream meters read around -18 dBfs.

11. If using a microphone directly into the Transmitter, consider enabling the Low Cut filter on the relevant stream, and AGC where input levels may be variable.

12. Navigate to the Outputs page and set Broadcast Name to something which users will be able to relate to the coverage area, for example the room name. Change Stream Name (Program Info) if desired.

13. Adjust encryption and sample rate settings as required.

14. If the second stream is being used, turn on the toggle switch to enable the radio and adjust the settings.

15. The Transmitter should now be broadcasting audio, connect a Receiver to confirm.

16. Adjust Transmit Power to the lowest level that provides full coverage of the intended area when the space is fully occupied.

Initial Setup

When first opening the application it will present a Devices list screen, with Devices and Version tabs to the left. Once logged in an additional Account tab will be shown.

On the Devices page each online device name is a clickable link, when clicking a device link for the first time you will be presented with a login dialog. If the device has already been configured it will prompt for the existing admin credentials. If the device is in factory defaults you will first be asked to provide the username and password you would like to use to manage your devices, then the default credentials which are printed on a label on the rear of the device.

Once authenticated with the first device, the software will automatically login to any other devices on the network which share the same credentials.

Note that there is no way to recover credentials once setup, other than a Factory Reset of the device. Ensure credentials are recorded in a secure place such as a password manager.

Remember Me

When logging in a Remember Me checkbox is enabled by default. When ticked this securely stores the username and password used to authenticate with the devices. Next time the application is opened you will be immediately prompted for the password. Entering the correct password will allow the software to authenticate with all online devices.

Devices Page

The devices page provides a list of all Transmitters and Docking Stations which the software has been able to discover on the network. It also lists devices which have previously been discovered but are not currently online.

There is a toolbar along the top which supports some key device functions, the available buttons will depend on your authentication state and which devices are currently selected.

The devices page can be toggled between the default table or a tile-based view, using the buttons on the right of the toolbar.

Firmware

The selection below describes the controls, see Updating Firmware for more information on the firmware update process.

  • Firmware – the tab in the bottom right of the software window opens a panel showing the available firmware packages. If no firmware has been downloaded yet then this will be blank, use the Download or Browse FW buttons to find available updates. When there are firmware updates available in this panel, one can be selected in order to apply it to online devices. Whenever a firmware package is selected the Devices list will be filtered to only show devices compatible with the selected firmware file. Click the Firmware tab again to close the panel.
  • Download FW – automatically downloads available firmware packages from an online repository. The Firmware panel will be automatically opened at the start of this process, it may take a few seconds for firmware packages to start being added to the list.
  • Browse FW – allows opening of firmware packages which have already been downloaded to a local storage location. Primarily used when Auri Manager is being used on a PC with no internet access. Once a firmware package has been opened the Firmware panel will be automatically opened.
  • Update FW – once a firmware package has been selected, select a compatible device which is online and authenticated to enable this button. Click this will then transfer the firmware update package to the device and instigate the update. The update will take around 10-15 minutes in total. The device status will be updated to show progress and notifications will be provided at key points in the firmware update process.

Identify

Active only when one or more online and authenticated devices are selected. Identify flashes an LED on the selected devices for 60 seconds. This helps confirm the right physical device is being selected before any further configuration and proves that network communication is working as expected.

Remove

Active only when one or more offline devices are selected. Allows offline devices to be removed from the list if these are not likely to be connected again.

Set Location

Active only when one or more online and authenticated devices are selected. Up to 4 levels of location hierarchy can be set to group devices when large numbers are available on the same network. For instance, in a university this may be used to segment devices by campus, building, floor and room.

Each input field will show a dropdown of existing locations at that level, which will be filtered as you type. To create a new location, click on the “Create New: location” option, or press the enter key. Existing locations are represented in blue, new locations are shown in green. Once all desired location levels have been set, click the Assign button.

Locations are then represented by a folder tree in the left side of the device listing. Clicking on folders filters the list to only show devices grouped within that location and shows any further levels of location nested below.

To see all devices click on the “Root” folder at the top of the list.

Notifications

The management software supports notifications for certain events. Notifications can be accessed by clicking the icon in the top right corner, which is available from all pages within the application. The icon also shows the number of new, unread notifications.

New, unread notifications show the device name in bold to distinguish them from previously seen notifications.

Some notifications in the panel can be clicked to see more detail in a dialog window.

Each notification can be individually dismissed by clicking the X on the right of the notification.

All current notifications can be dismissed using the “CLEAR” button at the bottom of the panel.

Click the icon again or anywhere in the main window to dismiss the notification panel.

Transmitter Configuration

When accessing a Transmitter, you will initially be presented with an Input screen. There are two other pages for Output and Settings configuration.

Input

This page allows configuration of the physical mic/line or Dante inputs to the device, as well as choosing how these are routed to each of the two streams that the Transmitter supports.

Input Controls

  • Input 1/2 Mode – this allows selection of microphone or line level input to set the right signal level. For Dante enabled devices a Dante option will also be available in this dropdown.
  • Input 1/2 Phantom Power – enables +24V phantom power for the given input to support condenser microphones. This is only shown when the input is in microphone mode.
  • Input 1/2 Gain – the sliders can be used to set the gain for each input, this is shown as a level relative to maximum gain (0dB) and provides an adjustment range of 40dB at 1dB intervals.
    • When AGC is enabled the input gain control will only have an impact at -30 and -20dB thresholds, as the AGC will take control of the fine gain.

Stream Controls

The streams are the audio channels which are managed by the transmitter, these streams can be broadcast over Auracast, sent to the analogue line out or sent over network audio to other Transmitters. Each stream runs in stereo within the Transmitter.

  • Source 1 – for each of the two streams this allows selection of whether the audio source will be taken from Input 1 Only, Input 2 Only, both inputs as a Mono Sum, both inputs treated as a Stereo Pair or the input Disabled.
    • Setting a stream input to Stereo Pair will automatically set the Radio Output to Stereo.
    • If either stream source is set as a stereo pair, the input modes, phantom power and input gain settings will be mirrored automatically between the two inputs and only a single set of input controls is shown.
    • You cannot route Input 1 Only to Stream 2, or vice versa.
  • AGC – allows a level of automatic gain control for the stream input. With this enabled the Transmitter will automatically adjust the input gains within a 20dB range to try and optimise the signal level. This is recommended when microphones are in use without any external dynamic control, as it helps avoid differences in volume between different talkers. When enabled an additional meter is shown to display the amount the AGC is reducing from full gain.
    • When AGC is enabled the input gain control will only have an impact at -30 and -20dB thresholds, as the AGC will take control of the fine gain.
  • Low Cut – enables a low cut filter on the given stream input, to help with intelligibility when microphones are directly connected to the Transmitter inputs. Note that the low cut filter knee frequency varies depending on the sample rate of the stream, see the Transmitter Technical Specifications for more information.
  • Mute – mutes the audio input to the stream.
  • Source 2 (Network Audio) – allows another Transmitter to be chosen as an input. The dropdown shows a list of all online Transmitters. Choosing a Transmitter from the list will configure it as an audio source, sending its stream over the network and setting the current Transmitter to receive that audio stream. This is primarily used when setting multiple Transmitters as repeaters in larger installations.
  • Mute – mutes the network audio input, if active.
  • Test Tone – temporarily disables the audio inputs to the stream and plays a sinewave tone for verification of the system.
  • Stream Meters – shows a live stereo signal level for the output of the given stream. The input gains or source audio levels should be adjusted to target the meters reading around the -18 dBfs level.

Output

The outputs page is primarily for adjusting Auracast related settings, but also allows control of functions such as an analogue line output.

  • Radio 1/2 – enables or disables the radio for each stream. If only one stream is in use, ensure the radio is disabled for the unused stream.
  • Broadcast Name* – sets the name that users will see when scanning for an Auracast broadcast. A unique Broadcast Name should be provided for each output of each Transmitter. This would commonly be set to represent the room name for example. Supports 4-14 extended ASCII characters.
  • Stream Name – sets the “Program Info” field, which some broadcast assistants may show a user when selecting an Auracast broadcast or for more contextual information while listening. Auri Receivers do not display this field.
  • Radio 1/2 Mode* – allows choice of whether the radio is broadcasting in mono or stereo. This is independent of the stream source, for instance it is possible to have mono source content and still have the radio set to broadcast stereo. Stereo radio mode will mean that two separate streams are broadcast, for left and right.
  • Encryption* – selects between an open broadcast or a secure encrypted broadcast. When enabled a separate Privacy Code field is shown.
  • Privacy Code* – sets the password (“Broadcast Code”) needed for users to connect to an encrypted broadcast. Should be 4-16 extended ASCII characters. Note that if encryption is enabled but no privacy code is set, the broadcast will be openly available.
  • Sample Rate* – selects from 16 kHz, 24 kHz or 48 kHz sample rate, which affects the frequency range of the broadcast. To be Auracast compliant as a venue, at least one radio must be broadcasting at 16 kHz or 24 kHz. Devices such as hearing aids are unlikely to support 48 kHz.
  • Transmit Power* – allows adjustment of the radio output power to reduce range when covering smaller areas. Expressed as a dBfs level relative to maximum output power.
  • Network Audio – enables or disables output of the stream to the network, used to send audio to repeaters. This will automatically be enabled if the Transmitter is selected as an audio input source for another Transmitter.
  • Line Out – enables or disables a balanced analogue line output which is available only on stream 1. This will be a mono sum of the stream 1 content.

* Changes to these settings will cause the radios to restart, this will lead to a short loss of audio. Auri Receivers will automatically reconnect when the broadcast becomes available again, however 3rd party receivers may need to be manually reconnected.

Settings

This page provides visibility and configuration of parameters relating to the Transmitter itself.

  • Device Name – set the name the Transmitter will be known by in the device listing, notifications panel and other areas of the management software.
  • Device Status – will report any errors or warnings related to the Transmitter.
  • Device Firmware – reports the currently installed firmware version.
  • Device Serial – the serial number of the Transmitter.
  • Region Code – designates the radio region of the device.
  • Device Uptime – the time that has passed since the Transmitter was last powered on or reset.
  • Administrator – reads back to username of the currently authenticated user.
  • Status LED – enables or disables the LED on the Transmitter so this can be turned off for installation in dark environments.
  • MAC Address – reports the MAC address of the Transmitter.
  • IP Address – the current IP address and whether this was obtained from DHCP, Auto (link local) or static configuration.
  • DHCP – enables or disables the DHCP Client on the Transmitter. When DHCP is enabled the Transmitter will wait 2 minutes for an address to be assigned by a DHCP server, after this the Transmitter will revert to an address in the link-local range (169.254.0.0/16)
  • The following fields are only active when DHCP is disabled and are used to set static network configuration. Note: any changes to network settings are only applied when the device is next restarted. Take care when assigning static IP addresses, misconfiguration may make the device uncommunicable.
    • Static IP Address
    • Subnet Mask
    • Gateway
    • Primary DNS
    • Secondary DNS
  • Network Audio Multicast IP – sets the IP address used for network audio streams between Transmitters. When setting up network audio streams the software will manage multicast addresses to ensure unique addresses are used for each group of transmitters, so this setting should not need to be adjusted. If there is a reason to adjust this due to a network conflict, it must be updated to the same IP on all Transmitters that are part of a network audio group.
  • Import / Export Settings – allows you to import or export a configuration file for a device. See below for more details.
  • Restart – restarts the Transmitter. This will not change any settings but will allow changes to network parameters to be applied.
  • Factory Reset – this will restart the device with ALL settings reset to the default factory configuration, including username and password.

Import or Export Device Settings

Tick boxes allow selection of which parameters to be saved based on the software settings pages, the system tick box includes device location. Select all for a complete device backup.

Usernames and passwords are never stored in a configuration file.

On Export the settings will be stored in an encrypted .auri file, named after the device name, date and time of export and saved locally in My Documents\Auri.

To import an existing settings file to a device you must first be authenticated with the same username as the device the file was exported from, then click Import and select the file. All settings stored in the file will be copied to the device regardless of which tick boxes are selected.

Dock Configuration

When accessing a dock, you will initially be presented with a Portables page. Library and Settings pages are also available.

Portables

This page is primarily to view and configure Receivers currently within the dock.

Receiver Settings

Docking stations are able to store a full Receiver configuration, the current configuration stored on the dock is read back to the controls at the top of this page and can be adjusted as required. Any settings changes will be immediately applied to all currently docked Receivers.

For an overview of the Receiver settings, see the Receiver section of the handbook.

Update Settings

  • Manual – Stored settings on the Docking Station will not be sent to newly docked Receivers automatically. Settings can be copied to all docked Receivers at any point by clicking the Apply Settings button. Library and settings can be copied using the left button of the Docking Station.
  • Auto Update Library – The library of 32 broadcasts will be automatically sent to Receivers as soon as they are placed in the dock. This will overwrite existing Receiver libraries, and if the dock library is empty the Receiver library will be wiped when docked.
  • Auto Update Settings – The Receiver settings stored on the dock will be automatically sent to Receivers as soon as they are placed in the dock, this will overwrite existing Receiver settings.
  • Auto Update Library and Settings – Both the library and Receiver settings stored on the dock are automatically sent to Receivers.

When library or settings are updated on docked Receivers, a spinning gear icon will be shown on screen.

A table is shown representing the number of slots in the Docking Station, when a Receiver is in any of the slots it will show in the corresponding table row, with the battery level, status, firmware version and serial number. There are also two buttons in each table row –

  • Identify – turns on the screen of the Receiver to confirm the right physical device is being selected before any further configuration and proves that communication is working as expected.
  • Factory Reset – resets the Receiver to factory default settings.

A single toolbar button is available –

  • Update All FW – sends the firmware package stored on the Docking Station to all currently docked Receivers. See Updating Firmware for more information.

Library

The docks can store a library of up to 32 broadcast names and privacy keys if needed. This library can be set to either automatically update any Receivers as soon as they are inserted into the dock, or so that a button press is needed on the dock for a transfer to happen.

The library is provided so that Receivers can connect to encrypted streams without having to manually enter a password, but also allows the Receiver to be locked down so that it will only connect to one or more pre-configured broadcasts.

This page allows each of the 32 library entries to be manually entered, or alternatively you can search and select from streams available from any Transmitters currently on the network, to copy the broadcast name and privacy keys automatically into the dock library.

The right panel will load the current broadcast library from the active dock. Each of these rows can be manually edited or can be removed by clicking the bin icon on the right.

A new blank row will automatically be added as needed, until all 32 rows are used.

The left panel lists the broadcast names for all online and authenticated Transmitters, so these can be selected to add into the dock library. Click anywhere on a row to add it into the dock library, the row will then be shown in a darker grey to indicate it is already present in the library.

In larger systems the search bar can be used to help find the required Transmitters and broadcasts.

Settings

Matches the options available on the Transmitter Settings page, with the exception of controls mentioned below.

  • Auto Update Portables – when enabled the Docking Station will automatically update the firmware of any Receivers that are docked with an older firmware version current installed. When disabled the Update FW button from the Portables page must be used to manually start an update for all docked Receivers.
  • Region Code, Status LED and Network Audio Multicast IP are not applicable to the Docking Station.

Account

The account page can be used to update the username and password used to authenticate with devices or delete the account entirely.

If the account is deleted, the factory default username and password will be reactivated.

Note that changes on this page can only be applied to devices which are currently online and authenticated. It is recommended to ensure all devices are connected when a change is made to avoid some devices being left on old credentials.

Changes to the account details will apply to ALL online authenticated devices.

The current username will be pre-filled.

  • Change Password – enter your current password and the new password, confirm the new password then click Submit.
  • Change Username – enter your current password and the new username, then click Submit.
  • Change Username and Password –enter your current password, the new username and the new password, confirm the new password then click Submit.
  • Delete Account – enter your current password and click Delete Account.

Usernames can include alphanumeric characters plus period, hyphen and underscore. Passwords support all characters.

Updating Firmware

Transmitters and Docking Stations

  1. Make sure the firmware package has been added to the application, using either the Download FW or Browse FW options.
  2. Open the Firmware panel and select the firmware package to be installed. Selecting a firmware package will filter the current device list to show only compatible devices.

3. Select one or more devices to be updated, then click Update FW to start the update.

4. The device states will show “Transferring” with a percentage to indicate progress while the file is sent to the devices, and a notification will be added.

5. Once Transferring completes the state will change to “Extracting” with a percentage to indicate progress while the devices are unpacking and checking the file is valid, and a notification will be added. This will take approximately 5 minutes.

6. Once the file is ready to be installed, the device will restart, state will show “Updating” with a percentage to indicate progress, and a notification will be added, this will take approximately 1 minute on a Docking Station and 5 minutes on a Transmitter.

7. At the end of installation the device will restart again and be rediscovered by the application. Confirm the firmware version has been updated as expected.

8. If the update fails for any reason, restart the device and try again. If it fails repeatedly contact support.

9. Note that the software must remain open and connected to the device until at least the “Updating” stage has started, if it is disconnected at any point before this the update will fail. The devices must stay powered on until the entire update has completed.

Receivers

Receiver firmware is included within the Docking Station firmware package.

  1. Ensure the Docking Station has been updated with the version to be installed on the Receivers.
  2. By default Docking Stations will be set to automatically update any Receivers that are docked running an older version. In this mode just dock the Receiver and the update will start.
  3. To disable the automatic update function, go to the Docking Station Device page and turn off the “Auto Update Portables” toggle.
  4. To manually start a Receiver firmware update, go to the Docking Station Portables page and click Update All FW. This will update all docked Receivers.
  5. The Receivers will show “Updating” in the Status column with a percentage to indicate progress. The software can be closed while this is in progress.
  6. While a Receiver is updating the top LED will flash red. It should not be removed from the dock while this is happening. When the LED goes white again the update is complete, and the Receiver can be removed.
  7. Receivers are updated in parallel, this means the update will take longer to complete if more Receivers are docked when the update is started.

Setting Encrypted Channels

By default the Transmitter broadcasts open, unencrypted streams. This is the recommended approach in public areas where ease of access for people using personal devices is most important. For more secure environments encryption can be enabled to limit who can connect to the broadcast.

  1. Navigate to the Transmitter in Auri Manager and click through to the Output page.
  2. For the broadcast to be encrypted, turn on the Encryption toggle and enter a password between 4 to 16 characters.
  3. Make a note of the password, this will need to be made available to any users who will connect with their own devices, for example it may need showing on signage within the coverage area.
  4. Navigate to the Docking Station which is serving the area to be covered by the encrypted broadcast and click through to the Library page.
  5. In the left panel locate the broadcast that was configured in step 2, this will be referenced as “TransmitterName – BroadcastName” in the list.
  6. Click on the broadcast and confirm that it has been added to a spare row in the Dock Library within the right panel. This will store the password in the dock and all currently docked Receivers.
  7. Remove a Receiver from the dock and confirm that it is able to list and connect to the broadcast.
  8. To ensure any Receivers docked in the future can access the broadcast, on the Portables page for the Docking Station set the Update Settings option to Auto Update Library. Alternatively the left button on the Docking Station can be pressed to transfer the library to docked Receivers at any time.

Connecting Repeaters

In scenarios where a single Transmitter is not able to cover the required area, multiple Transmitters can be linked together, enabling broadcast of the same audio content.

Auri Receivers are able to automatically connect to alternative Transmitters using the same broadcast settings. This means that if a user moves out of range from a Transmitter, once the signal has disconnected the Receiver will automatically scan and if an alternative Transmitter is available it will reconnect. It also means that when turning on a Receiver, if settings such as connection lock, library lock, or auto connect to previous are enabled, the Receiver will be able to connect to any Transmitter that matches the broadcast settings.

When performing a manual scan within range of multiple Transmitters using the same broadcast name, the Receiver will only show one of them in the list, and connect to the one with the strongest signal.

Note that other third party Auracast receivers may not support automatic reconnection or roaming between Transmitters.

There are two parts needed for a repeater configuration.

Audio Connections

Repeaters will generally need the same audio content to be connected to all Transmitters, this can be done by splitting the input audio signal, patching the same Dante output to all Transmitters, or by using the Auri network audio support.

To use network audio all Transmitters must be on the same network subnet. Network audio is sent as muticast RTP traffic, and it is strongly recommended to have IGMP configured properly if connecting to a wider network as without this multicast traffic will be treated as broadcast to all network hosts. This is not necessary if using Auri on a standalone, isolated network in which case a simple unmanaged switch can be used.

Start by making sure that a suitable audio source is connected to the primary Transmitter and that the input and stream settings are adjusted to give a suitable signal level. Connect to the broadcast and confirm everything works as expected with a single Transmitter.

In Auri Manager, go to the Inputs page of the repeater, click the “Source 2 (Network Audio)” dropdown and select the primary Transmitter from the list.

Both Transmitters will be configured automatically for network audio, confirm that the meters on the repeater are showing similar signal levels to the primary Transmitter.

Broadcast Configuration

Certain Output settings should be matched on the repeater to ensure that they work effectively together.

As a minimum, sample rate must be set to the same value, this will be automatically configured when setting network audio sources, but if changing sample rate later then all Transmitters within the network audio group must be updated to the same sample rate.

In most cases the broadcast name, encryption settings and stream name should be set the same as well, this will allow Auri Receivers to automatically connect to repeaters if they drop out of range from the primary Transmitter.

Once one repeater is configured, output settings can be quickly copied to other repeaters by using the Import/Export Settings option and selecting just the Output tick box when exporting a file from the first repeater. This same file can then be imported into any number of repeaters to configure their outputs.

There may be cases where it is preferable to name the broadcasts differently, for instance where Transmitters are allocated to different sections of a theatre naming the broadcasts as “Stalls” and “Circle” could help users connect to the most appropriate Transmitter. Note that in this configuration the Auri Receiver will not be able to automatically connect to repeaters. If a user moved out of range and the repeater is named differently, the user would have to rescan and connect to the alternative Transmitter.

Troubleshooting

No devices discovered in Auri Manager

Ensure devices have a network connection, are powered on and are on the same network subnet as the PC running Auri Manager.

If using link-local the devices will take around 2 minutes to obtain an IP address and be discovered.

Click the “Refresh” button

In most cases Auri Manager will request access to the network when first opened and permission should be granted, if no devices are being discovered then check the firewall settings; this is most commonly needed in link-local configurations.

In the Windows Start Menu search for “Allow an app through Windows Firewall”.

Click “Change settings” then scroll down the list to find “Auri Manager” and enable the checkboxes in all available columns.

RX1 Receiver will not power on

Make sure the Auri RX1 Receiver has a fully charged battery or is connected to a standard USB charger. Make sure the power button on the right side of the unit has been pressed for 1 second to turn the unit on. If this does not work, make sure the battery is installed properly or install a replacement battery. If using the Receiver for the first time, fully charge it using a USB charger or Auri Docking Station before use.

Receiver cannot connect to broadcast

Make sure the Receiver is within range of the Transmitter. If the broadcast is encrypted, ensure the details have been stored in the Receiver library through Auri Manager and a network connected Docking Station. Ensure the Receiver does not have “Library Lock” enabled, if so make sure the broadcast is added to the Receiver library.

There is no audio

Make sure the Auri RX1 Receiver is connected to the correct broadcast. Make sure the Auri TX2N Transmitter is powered on and has an audio source connected. Review the Transmitter Input settings in the Auri Manager application, make sure the correct input mode is selected, the stream sources are configured correctly and adjust the input gain such that the stream meters read approximately -18 dBfs. Make sure there is a suitable headphone or neck loop connected to the Auri RX1 and that the volume is set to a suitable level.

Audio is distorted

Review input mode and input gain on the Transmitter in the Auri Manager application. Adjust settings such that the stream meters read approximately -18 dBfs. Verify that the source audio being sent to the Transmitter is clean and undistorted.

Device state shows Firmware Error in Auri Manager

A firmware error can be shown due to a failed update or a corrupted image on the device. In some cases this may mean the device is running a recovery image with limited functionality. First try restarting the device and see if the state recovers to Online when rediscovered by Auri Manager. If the device still shows a Firmware Error after restarting, try installing the latest available firmware package for that device. If the error persists or the firmware update fails contact support.

Device does not boot or continuously restarts

The Transmitters and Docking Stations can be restarted into a recovery image by holding down the factory reset button while power cycling the device. After this has been done the device will be on the original firmware release with all settings erased. Update the firmware to the most recent version and reapply settings as needed.

Accessories

A complete range of accessories is available to complement your Auri system.

Neck loops allow Receiver compatibility for users with telecoil equipped hearing aids and cochlear implants.

The Auri RX1 is compatible with standard 3.5mm headphones or earbuds, a range of options are available from your Auri dealer.

Other accessories include spare battery packs, one-port USB chargers, cases and signage.

Introduction to ListenWIFI

ListenWIFI is a state-of-the-art assistive listening system that streams live audio at a venue over an existing Wi-Fi network to personal smartphones and dedicated receivers, enabling guests to hear the audio clearly in real-time. The ListenWIFI system has been designed to provide the right audio at the right time and place, even in the right language, seamlessly and automatically. It is used in a variety of applications and environments, such as classrooms, courtrooms, houses of worship, theatres and performing arts, stadiums, and arenas, just to name a few. Whether ListenWIFI is being installed to meet accessibility or compliance regulations, or you simply want to ensure your guests can hear the audio at your venue using their own smartphones, ListenWIFI is a flexible and easy to use solution that will ensure that your guests can hear every word and have a memorable experience. We are confident that you will love ListenWIFI.

This system manual provides information about ListenWIFI and all its components, including setup, deployment on your network, and ongoing management of the system. Additional support materials and resources, including tech notes, application notes, case studies, and recommendations, are available on our website at www.ListenWiFi.com.

How ListenWIFI Works

The audio server is the main component of ListenWIFI, being connected to live audio sources and the local area network. The server streams the audio it receives over the local network directly to wireless devices that are attached to the Wi-Fi network. Listeners can use either personal smartphones or receivers to access and hear the live audio.

An infographic with four circles numbered one through four with simple drawings in each circle. The first one says: Audio Source, Connect audio source to a ListenWIFI server and has a drawing of a microphone. Two says: Server, ListenWIFI server transmits the audio over Wi-Fi and shows a black box depicting a server. Three says: Smartphone, Access the audio on the free ListenWIFI app with a black rectangle depicting a cell phone. Four says: Listener, The user listens to the audio via headphones or a neck loop with a drawing of headphones.

Components

The ListenWIFI system consists of the following available components: 

 

Wi-Fi Audio Servers

The server is the main component of the ListenWIFI system. It is connected to the existing network to distribute real-time low-latency audio to mobile apps and/or dedicated receivers. Servers support up to 500 listeners and stream 2, 4, 8, or 16 audio channels depending on the model. However additional servers can be used to support more users and audio channels. Being designed as a highly scalable solution, additional servers can simply be plugged into the same local area network where both the channel and listener counts will simply be stacked from all servers.

Mobile Apps

The mobile apps are required for end users to stream audio directly to their own smartphone, which is available as free downloads for both iOS and Android devices at the App and Play Stores. Smartphones that have the app installed and running while connected to the Wi-Fi network will be able to discover and access audio channels on the network provided from the Wi-Fi Audio Server(s). Simply plug in wired headphones to listen (recommended) or an inductive neck loop for use with hearing aids equipped with a T-Coil. Audio channels are accessed via one of the available access methods:

1. Manual selection from an available channel list.

2. Automatic access to a channel when the user enters a certain room/zone. This is accomplished by using Beacons which enable automatic location-based triggering.

3. Scanning a QR code within the app to access a specific channel.

Channels can also be password/PIN-protected for any of the above access methods.

Wi-Fi Audio Receivers

Dedicated Wi-Fi Audio Receivers are small handheld devices that stream the audio from the Wi-Fi Audio server over the Wi-Fi network. Receivers are often required for venues that want to meet compliance laws that mandate receivers must be made available (ADA/CBC/IBC/DDA/etc.). Receivers are also beneficial for venues that would rather manage and check out dedicated hearing assistance devices, thus avoiding the hassle associated with supporting personal smartphones. Simply plug in wired headphones to listen (recommended) or an inductive neck loop for use with hearing aids equipped with a T-Coil. Audio channels are accessed via one of the available access methods:

1. Manual selection from an available channel list.

2. Automatic access to a channel is available when the user enters a certain room/zone. This is accomplished by using Beacons which enable automatic location-based triggering.

Channels can also be password/PIN-protected for either of the above access methods.

Beacons

Beacons are small wall-mounted units that allow for a fully automated experience at a venue. Beacons transmit a constant signal with information that the mobile apps and receivers can use to determine its relative location or proximity to an area or zone. By locating beacons throughout a venue, the correct audio channel can be delivered automatically to listeners based on their physical location, eliminating users needing to select a channel from a list or scan a QR code to obtain access. Beacons allow venues to seamlessly provide the right audio at the right time and place, even in the user’s preferred language. Beacons are an ideal accessory for any application with 2 or more channels or for single-channel applications where audio should only be accessible in a specific area. 

ListenWIFI Manager

The ListenWIFI Manager is a free Windows®-based software installation that is required for the configuration of ListenWIFI system components, including servers, mobile apps, receivers, and beacons. The Manager provides an easy way to access, configure, deploy, and manage all ListenWIFI equipment at a venue, including network configuration, channel names, and gain, channel visibility and access controls, channel routing, mobile app customizations, beacon automation, QR codes, firmware updates, inventory management, etc. The Manager software supports a full access administrator/owner account, and limited capability operator accounts to support day-to-day administration. The Manager software is not required to run persistently and is optional once the ListenWIFI system has been configured and deployed.

Accessories

Many accessories are available for the ListenWIFI audio line, including docking/charging stations for receivers, venue signage, ear speakers, headphones, neck loops, etc. More information can be found on our website at www.ListenWIFI.com.

System Set-Up

It’s recommended that the IT staff at your venue be involved during the set-up and deployment of the ListenWIFI system. Network and firewall settings may block the required traffic on the network, requiring the involvement of IT to ensure the proper network configurations have been implemented. See the Network Requirements section for more details.

  1. Install Wi-Fi Audio Servers on the Network
Front view of the LW-150P-02 two-channel server with Dante onboard.

a. Place the server(s) where it can easily be connected to power, audio source, and a network connection. The server can be rack mounted using the LW-327 ListenWIFI 2 Channel Server Rack Mount, or by using the rack ears provided (full width 1RU servers only).

b. Connect the server(s) to a power outlet using the provided power supply. Once plugged into power, the server will automatically turn on and the front power LED will flash blue until a valid network connection is established (next step).

c. Connect server(s) to the local area network, or router, using a Cat 6 ethernet cable (6’ cable provided). The front power LED will stop flashing and turn solid blue indicating a successful connection to the network with a valid IP address. Note that IP settings of the server can be managed via your router or using the ListenWIFI Manager Software.

d. Connect the audio sources to the server using any available audio inputs.

See the Wi-Fi Audio Servers section for more details.

2. Log in to the ListenWIFI Manager Software

a. Download and install the ListenWIFI Manager Software for Windows® located on the ListenWIFI support page. The Manager software should be installed on a computer that is kept local to the venue and can be accessed by system owners/administrators as needed. Please note that one login with full administrative access is allowed per ListenWIFI system, known as an Owner account.

b. Create the Owner account by specifying a username and password as well as security questions for password recovery. This account will be the owner of the venue with full administrative access. Please note that limited-access Operator accounts can later be created under the Owner account, providing operators with access to basic functionality of the ListenWIFI system such as inventory management and check-out mode.

For specific details on the ListenWIFI Manager, see the ListenWIFI Manager section. 

3. Assign Venue Wi-Fi Network

a. From the Venue page, assign the Wi-Fi network that the ListenWIFI system will be deployed on. This should be the same network or VLAN that the servers were connected to in Step 1c.  The Wi-Fi network can be assigned by selecting an available Wi-Fi network from the list and typing in the password, or by manually typing in the network SSID and credentials.   This Wi-Fi network will be programmed into all Wi-Fi Audio Receivers added to your venue.  If not using Wi-Fi Audio Receivers, this step is not required.  

4. Add Audio Server(s)

a. From the Servers page, discover and add Wi-Fi Audio Server(s) to your venue by clicking on the blue add icon. Make sure your computer is on the same local area network as your server(s) to facilitate discovery.  If your server(s) are not automatically discovered, it is possible that your network may block the automatic discovery protocol (mDNS), in which case you will need to manually add the server(s) using their IPv4 address.

 

b. Provide a friendly name for each added server. The default name of each server will show up as ‘Audio Server XXXX’ with the last 4 digits of the Server ID being represented, which is printed on the server’s label located on the bottom of the unit.

 

NOTE:  Once servers are added, the Manager will display ‘Connected’ towards the top, indicating that the Manager has an active connection to all server(s) added to your venue.  A ‘Connected’ status is required to edit many of the venue components throughout the Manager software, including servers, receivers, and mobile apps.

5. Configure Server Channels

a. Select a server from the Servers

b. Configure each server to stream either Mono (default) or Stereo channels by clicking on the Mono/Stereo switch in the center status panel.  Note that stereo operation will reduce the total number of channels by 50%. 

c. Click on the Mixer tab to access channel configuration options:

 

i. Name each channel as desired for display on listening devices.

 

ii. Choose if you want to Password/PIN protect each channel by clicking on the padlock icon and specifying an alphanumeric value, and specifying if the protection applies to mobile apps only, or to both mobile apps and receivers. This Password/PIN will need to be communicated to ListenWIFI users to access the channel(s). 

 

iii. Choose if you want to set channels as Visible (default) or Hidden, by clicking on the eye icon. When a channel is set to Hidden, it will not be displayed on listening devices for manual selection.  Hidden channels require a trigger to access the channel using either beacons (automated access) or QR codes (manual access).  

 

iv. Choose if you want to specify a Public Address (PA) channel by clicking on the announcement icon. When a PA channel is set, any audio detected on that input will temporarily be routed to all other channels for the duration of the audio presence. Note that only one PA channel can be set per venue across all servers. 

 

v. Adjust the gain of each input as needed for proper level control. Gain can be applied on each input in 6dB increments, up to a maximum of 24 dB of gain.

 

vi. Adjust the delay of each input as needed for proper alignment of audio to other sources, such as ambient sound, loudspeakers, video displays, etc. Delay can be applied to each input up to a maximum of 3 seconds of delay.

 

vii. If you have extra channels that will not be used, simply drag and drop the associated inputs to the bottom of the screen to the “Unused Inputs” section.

 

NOTE:  Multiple inputs can be bundled into a single channel to support multi-lingual listening applications.  Simply drag and drop inputs onto a channel and specify a unique language for each input.  This allows users access to any of the specified languages when they have access to the channel.  Additionally, users will automatically hear the channel in their preferred language based on the current language setting on the mobile app or receiver.

 

For specific details on server configuration options, see the Servers section.

6. Add and Configure Beacons

a. From the Beacons page, discover and add optional Beacons to your venue. This can be done using one of two available methods:

  1. Connect each beacon to the computer via USB cable. The beacon will automatically be added to your venue.
  2. Discover each beacon wirelessly using the “Scan for Beacons” feature. Make sure the beacon is powered on and Bluetooth (BT) is enabled on the computer.  Discovered beacons can then be added to the venue by simply clicking on the blue add icon.

b. Configure each beacon by selecting a beacon in the left panel. Beacons can be configured directly over USB or via a Bluetooth connection.  If the Manager does not have an active USB connection with the beacon when selected, it will attempt to connect over Bluetooth in which case you want to make sure that the beacon is powered and within range.

 

For specific details on beacon configuration options, see the Beacons section.

7. Add and Configure Receivers

a. From the Receivers page, add receivers to your venue by simply plugging them in directly via USB or through a Docking Station connected to the computer. Receivers are automatically added and assigned to the Venue Default profile. 

 

b. To configure receivers, click on the Venue Default profile which will highlight all receivers assigned to the profile and opens a profile editor to the left.

 

  1. Under the Settings tab, configure the receivers preferred listening language, default volume, display brightness, and power saving modes as desired.
  2. Under the Beacons tab, select the audio channel to be automatically played when the receiver enters the range of an assigned beacon (if using beacons). Note that beacons must first be added to the venue before you can assign channels to be automatically played.

 

Tip:  Profiles are simply a saved configuration or group of settings that can be applied to one or more receivers. Additional profiles can be created by clicking on the + icon towards the top of the screen. Profiles can easily and quickly be assigned by dragging and dropping the profile onto a receiver.

For additional details on receiver configuration options, see the Receivers section.

8. Configure Mobile Apps

a. From the Mobile Apps page, access individual customization options and configuration settings for guests choosing to connect to the audio with their own smartphones.

 

b. Configure the mobile app appearance by clicking on the following sections:

    1. Welcome screen (logo, video, or image)
    2. Define app theme colors
    3. Upload banner images
    4. Upload channel images
    5. Upload documents
    6. Upload offers

c. Under the Beacons section, select the audio channel to be automatically played when the receiver enters the range of an assigned beacon (if using beacons). Note that beacons must first be added to the venue before you can assign channels to be automatically played.

d. Create and print Channel QR codes by clicking on each channel and tapping the QR code icon. Note that these QR codes are only needed if Beacons will not be used to automatically connect listeners to the proper audio channel.

For additional details on mobile app configuration options, see the Mobile Apps section.

9. Functional Testing

a. Using a smartphone:

    1. Connect to the Wi-Fi network.

Wi-FI Audio Servers

Quick Reference: 

ListenWIFI 2 Channel Wi-Fi Audio Server (Analog)

ListenWIFI 2 Channel Wi-Fi Audio Server (Dante):

ListenWIFI Multi-Channel Wi-Fi Audio Server (Analog)

NOTE: Images of server models shown above are for reference purpose only. Some server models may vary in appearance.

Audio Inputs: 

The following audio sources are available depending on the specific model of server: 

  1. RCA Audio Inputs: Use the provided RCA connection cable to input audio to the server. The RCA connectors are consumer line level, unbalanced, and sum-t-mono input. 
  2. Terminal Block Inputs: Connect audio to the server using the terminal block connectors on the server. The terminal block connectors are professional line-level balanced inputs 
  3. Dante Input: Connect the provided Cat6 cable from the Dante® network to the servers Dante input. Please note that Dante® settings can be accessed and managed via the Dante Controller® software available from Audinate®.

Note: Servers are default configured to operate in mono. To change the audio to stereo operation, connect the audio to the right and left audio inputs and configure the server for stereo operation in the ListenWIFI Manager software. 

For additional information on how to properly wire and connect audio to your server, please see the “Audio Input Connections” Tech Note available at ListenTech.com/listenwifi-support

Audio Indicator Lights and Audio Gain: 

For servers with analog inputs, active audio level lights on the front of the server indicate audio levels being received by the server (see image). To ensure proper gain, make sure that the audio indicator light is flashing green on a regular basis indicating a good audio level. If the audio indicator light is not being lit often or not at all, input gain needs to be applied to ensure an adequate level on the listening devices. We recommend that the gain be turned up at the sending device prior to being input to the server to allow for the best signal to noise ratio and audio gain performance. If this is not possible, then the gain be turned up inside of the server using the ListenWIFI Manager software. Up to 24dB of gain can be applied as required in 6dB increments. See the ListenWIFI Manager Software section for additional details. 

 

Server Load: Each server can deliver between 1 – 16 channels, while supporting up to 500 listening devices including mobile phones and Wi-Fi Audio Receivers. If additional channels or higher user counts are needed, ListenWIFI can easily be expanded by stacking servers allowing up to 512 channels and 16,000 users! See Server Stacking section below. 

Server Stacking: ListenWIFI is a scalable solution that can easily be expanded to support additional channels and users at any time. By simply plugging additional servers into the same local area network, the ListenWIFI servers will operate as one system offering more channels and able to support additional listening devices. This flexibility allows venues to deploy a smaller number of channels or rooms today, while allowing easy expansion into additional rooms and channels later. This flexibility also allows servers to be physically located throughout a venue in different areas or rack closets, supporting the needs of larger venues who may require a distributed system. This approach also ensures that if one server goes down, only some channels will become unavailable and will not take down or impact the entire ListenWIFI system. Up to 32 servers can be placed on the same local area network. 

 

For more information, please reference the “Server Stacking” Tech Note available at https://www.ListenWIFI.com/support.

Input and Channel Configurations

ListenWIFI servers are in mono by default, with input 1 pointing to channel 1 output, input 2 pointing to channel 2 output, etc.  This configuration can easily be changed in the ListenWIFI Manager software, allowing any input to be associated with any channel output by simply dragging and dropping the inputs around.  Inputs and Channels settings are accessible by clicking on the Server page, selecting a server, and clicking on the Mixer section.

Input Settings:

  • Gain: Up to 24 dB of gain can be applied to each input, in 6dB increments.
  • Delay: Up to 3 seconds of delay can be applied to each input, in 20 mS increments.

 

Channel Settings:

  • Channel Name: Channel names appear on both mobile apps and receivers and can be customized using alpha-numeric characters and some special characters. 
  • Hidden Channel: When a channel is hidden, it is not displayed for manual selection on listening devices. Hidden channels instead require the use of a beacon where users are automatically connected to the channel when they enter the range of a beacon.  Alternatively, QR codes can be used with mobile devices, allowing access to the audio channel when the QR code is scanned.   By default, channels are visible and displayed on listening devices for selection. 
  • Locked Channel: For highly secure applications where Hidden channels do not provide enough security, password protection can be enabled per channel.  Whether the channel is hidden or visible, when the channel is selected the user will be prompted with the input of the password.  Locked channels can be applied to mobile devices only, or mobile apps and receivers both. 
  • PA Channel: A Public Address (PA) channel can be set to override all other channels temporarily whenever the presence of audio is detected on the PA channels associated input. This feature is useful for emergency override and public address announcements, as the audio is routed to all listeners regardless of what channel they are listening to.  Once the PA override event ends, the listeners will be returned to their previous channel.  One Public Address channel (PA) can be set per Venue across all servers. 

Multi-Lingual Audio Configuration:

For venues who have multi-lingual audio channels, ListenWIFI can be configured to associate multiple inputs (languages) to an individual channel.  For a multi-lingual channel configuration, multiple inputs are associated to a single channel output.  From the Server Mixer tab in the ListenWIFI Manager software, simply drag and drop multiple server inputs to the same channel output and specify the language of each input.   When a user accesses that channel, multiple languages will be made available on the listening devices which the user can select from.  See ListenWIFI Manager section for more details.

Network Settings

TheListenWIFI server is by default configured as a DHCP client, which means it will receive an IP address, subnet mask, gateway, and Domain Name Server (DNS) address automatically from the network it is plugged into.  If it is desired to configure the IPV4 settings directly on the server, click on the Servers page in the Manager software, click on the server and select the Network tab to specify these IPV4 settings (see image).

ListenWIFI audio packets are prioritized over other network traffic using Quality of Service (QoS) to ensure that ListenWIFI audio streams are sent over the network as quickly as possible, high priority, to ensure low latency for live audio applications. ListenWIFI audio packets are prioritized using a Type of Service (TOS) or Differentiated Services (DS) field, which is set to “0xB8” by default.  This field can be changed as needed depending on the network by editing the TOS/DS field. Typical values are 0xD8 or 0xB8 depending on the local network.  Some experimentation may be required to choose the optimal value.  

Additionally, the priority of the network traffic can be set based on the VLAN priority of either Voice or Video.  The default value of “Voice” is recommended but can be changed to Video if it provides a better experience on your network with lower latency and less dropouts. Some experimentation may be required to choose the optimal value.

Mobile App

Operational Instructions: 

  1. Download the FREE ListenWIFI Mobile App:

The mobile app is available to download for free, without any advertisements or recurring payments required. 

2. Join the venue’s Wi-Fi network. This can be accomplished by manually selecting the network from the phone’s Wi-Fi list, or by scanning a Wi-Fi connection QR code using the phone’s camera. 

 

Tip:  Wi-Fi Connection QR codes can be generated from the ListenWIFI Managers Venue page.

3. Launch the app and listen on your smartphone. Audio channels are then accessed depending on channel configuration: 

  1. Visible Channels: Channels are always visible within the mobile app and accessible to the user.  Channels are manually selected from the available channel list. Simply swipe up and down to navigate and tap on a channel to begin streaming that audio channel.  Tap on the channel again to pause/play or select a different channel to listen to.
  2. Hidden Channels: Channels are hidden from view on the mobile app and require the mobile device to receive a trigger to access the audio channel.  This trigger can either be automated using installed beacons, or manual using QR codes:
        1. Listen Beacons – Requires the user to be in a specific location where the channel is then made available in the mobile app when in range of a beacon. The mobile app will only have access to 1 hidden channel at a time.  When a user enters a specific room or zone, the channel will automatically appear on the display and begin playing.  When the user leaves the area or enters another beacon zone, that channel can also be removed from the display (configurable via Exit Timeout).  
        2. QR Codes – Requires users to scan a QR code when in each room or zone to access the audio. These QR codes are generated from the Manager software and be printed or exported directly from the software.   Users simply use the in-app QR code scanner to access the audio channels in each room.  Only one hidden audio channel can be accessed at a time. 
        3. Hidden and Visible Combination: Some channels are always visible and available for selection, while others require that the mobile device receive a trigger to access the audio (either automated using Beacons, or manually using QR codes).

 

Channel configuration is available in the Servers Mixer section of the Manager software.  When using Hidden channels and beacons with the mobile apps, subscription to those beacons is required which can be configured in the Mobile Apps beacon section of the Manager software. 

 

Tip:  It is recommended that wired headphones be used with ListenWIFI to ensure low audio delay when lip sync is important.  The use of Bluetooth® devices is not recommended due to the significant latency that it can introduce. 

QR Code Scanner: 

The ListenWIFI mobile app has a built in QR code scanner, allowing users to access a channel directly by opening their camera and scanning a ListenWIFI channel access QR code.  The in-app QR code scanner is accessible via the bottom of the app to the right (see image).   QR codes can be generated for each channel directly in the ListenWIFI Manager software.  See ListenWIFI Manager section for details on creating QR codes. 

Language Selection:

The language can be changed (when available) at any time by tapping on the language selector at the bottom of the mobile app.  All available languages for the current channel will be displayed and made available for selection.  Once set, the mobile app will stream audio channels in this language when available.  See Servers section for Multi-Lingual audio setup. 

Loudspeaker Mode: 

The ListenWIFI app features a loudspeaker mode (disabled by default), routing the audio to the phones loudspeakers and allowing the audio to be amplified for listening without headphones.  By default, this feature is turned off and the ListenWIFI mobile app audio can be heard by directly holding the smartphone up to the ear and listening via the phone call speaker. 

Alternatively, headphones can be directly connected to the headphone or USB-C jack, which will override the audio coming from the phone’s speakers. 

 

Tip:  When using headphones with ListenWIFI, it is recommended that wired headphones be used to ensure low audio delay when lip sync is important.  The use of Bluetooth® devices is not recommended due to the significant latency they can introduce. 

Customizable App

The ListenWIFI Mobile App supports customized content and venue branding.  The following assets can be customized using the ListenWIFI Manager Software by simply pointing and clicking on the individual items and specifying the content:

  1. Welcome Screen – Upon app launch and successful connection to Wi-Fi Audio Servers on the network, a welcome screen can optionally be shown to mobile app users (disabled by default). The welcome screen can support images (JPG, PNG) or videos (MP4) up to 5MB in size.  Additionally, an optional skip feature can be enabled allowing users to skip the welcome screen after a specified duration (3 seconds to 30 seconds). 

 

  1. App Theme – The app title can be customized allowing the venue to place a custom name at the top of the app. Also, the primary and secondary colors of the app can be modified using a color palette or by specifying HEX or RGBA color values.

 

  1. Sliding Banners – The mobile app can display up to six sliding banners, which are on rotation towards the top of the app. These sliding banners are clickable images, allowing the user to click-through the banner to additional content including supporting images and text, as well as a link to a “More Info” button which points to a specified website URL.

 

  1. Channel Images – Small channel images are shown when viewing a channel, while large channel images are shown when streaming audio.  These channel images can be customized to match the channel name, room, topic, etc. 

 

  1. Info– The second tab in the app supports up to six PDF documents, up to 5MB in size. The info tab can be used to upload important information about the venue, calendars, maps, schedules, etc.  These PDF documents can also be placed in custom categories and ordered as needed.  

 

  1. Offers – The 3rd tab in the app supports up to six offers, which can be used to highlight specific offers or events. Each offer has a dedicated space within the mobile app that users can quickly and easily find, including a custom title with supporting images.  Additionally, when the user clicks on the Offer, they can be shown additional content and link to an external website by specifying a custom URL.

Once customized, the ListenWIFI mobile apps will automatically show the specified content upon successful connection to the Wi-Fi Audio Server(s) on the network.  Please note that the app does not show this customized content until it has successfully connected to a server on the network. 

Using Beacons with ListenWIFI Mobile App

Mobile Apps are capable of automatically triggering to a specified channel when they receive a signal from Listen beacons.  By installing beacons in individual rooms or zones, users are automatically connected to the audio for that specific room without any user interaction, providing a completely automated experience.  These Listen beacons emit a Bluetooth Low Energy (BLE) signal that the mobile device can pick up, enabling the app to automatically change its channel based on the channel specified.

By adding beacons to the venue in the Manager software, all beacons become available for mobile apps to trigger from and are listed under the Beacons tab of the Receivers page.  Simply check the Beacon that you want mobile apps to respond to, and then specify the audio channel that they should play by selecting a channel from the list of available channels.  Please note that the range and responsiveness of the beacon can be changed by adjusting the power level of the beacon under the Beacons section of the ListenWIFI Manager software (see Beacons section for more details). 

In addition to specifying what channel mobile apps shall trigger to when they encounter a beacon, you can also specify what should happen when the mobile device leaves the range of the beacon;  audio can continue streaming until another beacon is encountered, OR the app can be disconnected from the audio channel as soon as it leaves the range of the Beacon.  This behavior is specified by the Exit Timeout feature.

 

Exit Timeout:   This feature defines whether the app should remain connected to the audio channel or disconnect once they leave the range or area of the beacon.  Exit Timeout is disabled by default, allowing mobile apps to continue streaming audio until another beacon is encountered.  When Exit Timeout is enabled, users will automatically be disconnected from this channel when they leave the range of beacon.  A value can be set allowing you to specify the time a user can remain connected once they leave the range of the beacon, from 10 seconds up to 10 minutes.  It is important to note that if Exit Timeout is enabled, the user will lose access to the audio unless they remain within the range of the beacon, requiring the entire room or space to be properly covered with the beacon signal (see Beacons section and footprint).

      2. LA-481 – Docking Station Case 16
      3. LA-482 – Docking Station

2. Connect a USB charger to the micro-USB port on the side of the receiver.

The receiver will typically charge in about 2-3 hours.  For completely dead batteries, it may be required to leave the receiver connected to a charger for up to 4 hours.  Note that the receiver can be used while charging but will extend charging time.

Operational Instructions:

Prior to use, receivers must first be added and configured via the ListenWIFI Manager software.  This step is required for the receivers to establish communication with the Wi-Fi network and communication with the Wi-Fi Audio Servers on the network.  Once added, the receivers will connect and begin streaming real time audio.  See Setup section. 

  1. Remove the receiver from the charger and turn the receiver on.
  2. Plug in wired headphones to listen, or an inductive neck loop for use with hearing aids equipped with a T-Coil.
  3. Allow receiver to connect to the specified Wi-Fi network. The display will indicate a successful connection, and the Wi-Fi icon will indicate signal strength.
  4. Allow the receiver to connect to all Wi-Fi Audio Servers on the network.
  5. Audio channels are then accessed depending on channel configuration:
          1. Visible Channels: Channels are always visible on the receiver and accessible to the user.  Channels are manually selected from the available channel list. Simply use the soft buttons to navigate the channel list up and down to select the channel and the audio will begin playing immediately.
          2. Hidden Channels: Channels are hidden from view on the receiver and require the user to be in a specific location, using Listen beacons.  Channels are made available on the receiver when in range of a beacon and then become unavailable when the receiver leaves the range of the beacon.  The receiver will only have access to 1 hidden channel at a time.  When a user enters a specific room or zone, the channel will automatically appear on the receiver display and begin playing.  When the user leaves the area or enters another beacon zone, that channel can also be removed from the display (configurable).
            1. Hidden and Visible Combination: Some channels are always visible and available for selection, while others require that the user be in proximity to a beacon for access. Channel configuration is available in the Servers Mixer section of the Manager software.  When using Hidden channels and beacons with the receiver, subscription to those beacons is required, which can be configured in the Receivers beacon section of the Manager software.

        6. Adjust the volume to a comfortable listening level using the side volume buttons.

        7. The language can also be changed (when available) by pressing the right soft button for 3 seconds, navigating the list using the up/down side buttons, and confirming with the right soft button.

        8. Once done listening, turn off the receiver by pressing the power button for 3 seconds.

        9. Return receiver to the charger.

Receiver Profiles

Receiver settings are managed via “Profiles”, which are simply a group of settings that will define how the receiver will behave in a venue.  Receiver profiles are accessible via the Receiver page in the ListenWIFI Manager software only.  Each profile includes the Settings tab and the Beacons tab, allowing you to specify preferences such as default language, display brightness, etc., as well as specify which channels the receiver shall trigger to when it encounters specific beacons (for venues using beacons).  Receivers can be managed individually or as a group using the profiles setup.  You can create as many profiles as you like, creating unique experiences for different users or events.  Once profiles are created, you can simply drag and drop a profile onto a receiver in the Manager software to load that profile or specific user experience to a receiver.

Wi-Fi Credentials

The assigned Wi-Fi network and credentials are specified on the Venue page in the ListenWIFI Manager software.  Once the Wi-Fi network is specified for a venue, the Wi-Fi credentials will be shared with all receivers that have been added to the venue.  There is no need to program the Wi-Fi credentials into each receiver individually.

Receivers Settings: 

  1. Default Language:  For multi-lingual venues a default language can be set.  The receiver will stream this language whenever that language is available for a specific channel.  If there is not more than one language, then the receiver will simply play the available channel in its floor language.  In the case where alternate languages are available, but not the language specified by the receiver, it will fall back to the language at the top of the channel list as specified under Server channels in the Manager.  The language can also be temporarily changed directly on the receiver by long pressing the right soft button to access the language menu and using the side buttons to navigate to a different language available.  The receiver will return to its programmed default language upon a power cycle or insertion into the docking station.

 

  1. Default Volume: The default listening volume can be adjusted from 0 to 100%, allowing venues to properly set the default volume based on the application, channel levels, ambient noise levels, listening audience, etc.  The default volume is set to 35% by default. 

 

  1. Brightness: The brightness of the OLED display can be adjusted as follows:
    1. Off – the display will not illuminate at all unless the status button is pressed.
    2. Dim – the display will be dimmer for dark environments.
    3. Bright – the display will be bright for brighter environments.
    4. Auto (default) – the display will adjust itself based on the ambient lighting conditions.

 

  1. Auto Off: This power saving mode is enabled by default, where the receiver will automatically power off after a duration of audio silence.  The power off interval can be adjusted from 10-30 minutes or disabled.  This feature is set to 30 minutes by default. 

 

  1. Jack Sense: The receiver will automatically power on when headphones or ear speakers are plugged into the headphone jack.  Also, the receiver will turn off after 60 seconds of headphone removal.  This feature is enabled by default and can be disabled.  

 

  1. Auto Power: The receiver will automatically turn on when removed from the charger and turn off when connected to a charger.  This feature is enabled by default but can be disabled.  

Using Beacons with Receivers:

Receivers are capable of automatically triggering to a specified channel when they receive a signal from Listen beacons.  By installing beacons in individual rooms or zones, users are automatically connected to the audio for that specific room without any user interaction, providing a completely automated experience.  These Listen beacons emit an Infrared (IR) signal that the receivers can pick up, allowing the receiver to automatically change its channel based on its assigned receiver profile which specifies a channel for each assigned beacon.     

By adding beacons to the venue in the Manager software, all beacons become available for receivers to trigger from and are listed under the Beacons tab of the Receivers page.  Simply check the Beacon that you want the receiver(s) to respond to, and then specify the audio channel that the receiver should play by selecting a channel from the list of available channels.  This configuration can then be saved as part of a receiver profile, enabling any receiver with this profile to automatically trigger when in range of the beacon.  Please note that the range and responsiveness of the beacon can be changed by adjusting the power level of the beacon under the Beacons section of the ListenWIFI Manager software (see Beacons section for more details). 

In addition to specifying what channel the receiver shall trigger to when it encounters a beacon, you can also specify what should happen when the receiver leaves the range of the beacon; the receiver can continue streaming the audio channel until it encounters another beacon, OR  it can disconnect from the stream as soon as it leaves the range of the Beacon.  This behavior is specified by the Exit Timeout feature.

 

Exit Timeout:   This feature defines whether receivers should remain connected to the audio channel or disconnect once they leave the range or area of the beacon. Exit Timeout is disabled by default, allowing the receiver to continue streaming the audio channel until it encounters the next beacon.  When Exit Timeout is enabled, users will automatically be disconnected from this channel when they leave the range of beacon.  A value can be set allowing you to specify the time a user can remain connected once they leave the range of the beacon, from 10 seconds up to 10 minutes.  It is important to note that if Exit Timeout is enabled, the user will lose access to the audio unless they remain within the range of the beacon, requiring the entire room or space to be properly covered with the beacon signal (see Beacons section and footprint).

Unit Menu:  The receiver’s main menu can be accessed as follows:  

  1. Press and hold the power and volume down buttons simultaneously for 2 seconds.
  2. Using the volume buttons, navigate up and down throughout the menu.
  3. Select one of the following menu items by pressing the right soft key:

 

  • Reset Device: Reset the unit to factory defaults by confirming with the right soft key.

 

  • About: Displays the receiver’s information – Model, Serial Number (S/N), Firmware Version, Region Code, SSID, IP address, FCC ID, IC ID, and MAC address.   

The unit menu can be exited at any time by momentarily pressing the left soft key or power button.  Alternatively, the unit menu will automatically exit after 10 seconds of no activity.

Beacon Overview

Beacons provide an automated listening experience by connecting mobile apps and/or receivers to the proper audio channel based on their physical location.  By simply installing beacons in different rooms or areas, users are automatically connected to the right audio channel for that area when in range of the beacon, and optionally disconnect when they leave the range of the beacon.  Beacons simply broadcast a small amount of data that, when in range, the receivers and/or mobile apps use to determine which channel they should be streaming. Listening devices simply use the information from the beacons to make a channel change according to how listening devices have been configured to react.  Beacons are programmed to be used with mobile apps only, receivers only, or both mobile apps and receivers depending on the preference of the venue. 

Beacons are advantageous for any application that has multiple channels available for different spaces.  They provide privacy at a venue by ensuring users are connected to the proper audio channel, while also prohibiting access to other audio channels from adjacent rooms or spaces.  Instead of relying on channel password authentication to meet privacy concerns, beacons can eliminate the need for passwords by providing physical authentication where the listener must physically be in the room to access the audio.  Additionally, instead of forcing users to select from a list of available channels in the app, beacons allow channels to be hidden by default and then made available when in the range of the beacon.  Also, beacons offer advantages over providing QR codes for channel access, as QR codes are not automated, must be scanned, and can introduce security concerns.  Beacons provide an elegant and automated user experience that solves these concerns for many applications. 

Beacon Setup

Prior to use, beacons must first be added to a venue in the ListenWIFI Manager software. This can be accomplished by connecting the beacon via USB into the PC with ListenWIFI Manager software, in which case the beacon will automatically be added to the venue.  Alternatively, the beacon can be discovered and added wirelessly from the Manager software via Bluetooth.   

 

Once added, the beacons can then be configured as desired according to the settings described below.  Once configured, mobile apps and receivers can then be programmed to trigger from these beacons.    

  1. Bluetooth Triggering – Enables a Bluetooth beacon transmission allowing mobile devices to receive the beacon. Can be enabled or disabled (default enabled). 

 

  1. Bluetooth Power – Adjust the effective range of the beacon for mobile devices.  Can be set to Low, Medium, or High (see Beacon Range table).

 

  1. Infrared Triggering – Enables an Infrared beacon transmission allowing Wi-Fi Audio Receivers to receive the beacon. Can be enabled or disabled (default disabled). 

 

  1. Infrared Power – Adjust the effective range of the beacon for receivers. Can be set to Low, Medium, or High (see Beacon Range table).

 

  1. Transmit Interval – Adjusts how often the beacon signal is broadcast. Adjustable from 300mS up to 5 seconds (default 1 second).  A faster interval allows for a more responsive trigger from listening devices but increases the power consumption. 

 

  1. LED Indicators – Enable/disable the blue status LED flash every 5 seconds shown during normal operation. Default is enabled. 

 

  1. Low Battery LED – Enable/disable the red status LED flash every 5 seconds shown when batteries are low. Default is enabled. 

 

  1. OTA Configuration – Enable/disable the over-the-air (OTA) connection method for configuration. When disabled, the device cannot be connected to via Bluetooth for configuration and must be directly connected via USB. 

Powering Beacons

Beacons can be powered via a direct USB micro connection or by installing 2 AA alkaline batteries.  Direct USB power is recommended whenever possible.  USB power can be routed directly into a single gang electrical box via the cable access cutout in the mounting bracket or routed directly down the wall to an outlet via the integrated cable trough.  If using batteries, please reference the beacon battery life section.  It is important to note that battery powered beacons will operate at a maximum level of medium power when infrared triggering mode is enabled. 

Beacon Installation

Beacons can be mounted to a wall or to a ceiling directly to a single gang electrical box, or directly attached to sheetrock or flat surface with the mounting bracket and screws provided.  It is recommended that beacons be installed central to the listening area, as much as possible.  Generally, the main thing is to ensure that all users in a room or zone are within range of this beacon and the beacon signal is stronger than any other beacons installed at the facility.  This ensures that listening devices are triggered to the correct channel for that space, and users are not falsely triggered to alternate rooms or channels.  This is often best accomplished by ensuring that the beacon is placed in a central location with adequate coverage of the room or zone. 

Beacon Range

The range of the beacon is dependent upon many factors, including transmission mode (IR or BT), number of walls and obstructions, signal bounce, body attenuation, listening device sensitivity, etc.  It is important to keep this in mind during design and installation of these beacons and error on the safe side to ensure adequate coverage.  Multiple beacons can be used to extend the range or footprint of the beacon signals. 

The following table lists typical line of sight range values for each transmission mode at the 3 different power levels available: 

Power Level

Low

Med

High

Infrared (IR)

10 feet (3 meters)

30 feet (9 meters)

110 feet (33 meters)*

Bluetooth (BT)

10 feet (3 meters)

30 feet (9 meters)

110 feet (33 meters)

*Requires direct USB power, battery power will operate at Medium

 

The range of the beacon will be dependent upon environmental conditions and listening device sensitivity, especially with Bluetooth (BT).  It is essential to tailor your design approach based on specific requirements and environmental conditions.  Multiple beacons can be used to extend the range or footprint of the beacon signals in larger areas.  Some experimentation may be required to choose the optimal beacon locations.

Beacon Battery Life

Beacons can operate using 2 AA alkaline batteries when needed. The use of batteries is generally only recommended for temporary deployments at venues, or when flexibility and movement of beacons is required such as during experimentation with beacon placement.  If using batteries in a permanent installed environment, a scheduled battery replacement plan should be implemented.  

Battery life is largely dependent upon the triggering protocols enabled, as well as the transmit power and interval.  Bluetooth consumes very little power, while Infrared consumes more power.  The tables below highlight the expected battery life for each mode of operation across a few different configurations.

 

 

Bluetooth Triggering

When using both Bluetooth and Infrared modes simultaneously, the Infrared Triggering battery life table should be referenced.  Battery life is calculated using new alkaline batteries to the time where the beacon is flashing low battery LED. Once the beacon indicates low battery, it is recommended to replace the batteries as soon as possible to avoid a range reduction from the beacon.

ListenWIFI Manager Software

Overview

The ListenWIFI Manager software is a comprehensive setup and management tool for Windows®, designed for the configuration and management of all ListenWIFI system components, including servers, mobile apps, receivers, and beacons. This authentication-based software ensures that all ListenWIFI components are securely added and linked to a primary owner’s account. This provides robust security and ownership, preventing unauthorized access and tampering with system configurations. Only the owner’s account can access the system hardware configurations, ensuring a tamper-proof and secure environment.

The Manager offers a user-friendly interface to access, configure, deploy, and manage all ListenWIFI equipment at a venue. It supports a wide range of functions and equipment configurations, including channel naming and gain adjustments, channel visibility and access controls, channel routing, mobile app customizations, beacon automations, QR code generation, firmware updates, inventory management, and more.

Minimum Specifications

The ListenWIFI Manager can be installed on Windows machines that meet the following requirements:

  • Supported Operating Systems:
    • Windows 10
    • Windows 11
  • Minimum Requirements:
    • .NET Framework of version 6.0 or higher
    • Processor: 1 GHz or faster
    • RAM: 2 GB or more
    • Disk Space: 1000 MB of available space

Setting up the ListenWIFI Manager

  1. Manager Download

To gain access to the Manager software, visit www.listentech.com and navigate to the ‘ListenWIFI Support’ page.  From this page, select ‘Request ListenWIFI Manager Software’.   Simply fill out the form and a download link will be provided.    

 

  1. Manager Installation

The software should be installed on a central computer that has access to the same local area network where ListenWIFI will be deployed, either via a wired or wireless connection (wired recommended). The software can also be installed on a virtual machine on the network, allowing multiple users to access the software from their personal computers. The software should be accessible by administrators who are involved with configuration and deployment of ListenWIFI, and optionally to venue personnel who may need continued access for day-to-day operations and inventory management.  It is important to note that the software is only required for initial setup and deployment and is not required to be continuously open or running once configured.

Creating Accounts

Upon opening the software, you will be prompted to create an account.  This includes specifying your login credentials such as username and password, as well as setting up security questions and answers in case your password is forgotten.  This account is referred to as the ‘Owner’ account and is the main ListenWIFI Manager account. 

Owner Account:  The Owner Account provides full administrative access to all ListenWIFI components within the Manager software on the installed computer. Logging into the Owner Account is crucial for discovering and configuring ListenWIFI components at the venue. Once components are discovered and added to this account, they become exclusively associated with the Owner Account. This ensures that owned equipment cannot be added or discovered via other accounts or computers, thereby preventing tampering of system settings and ensuring the security of all system components.  One Owner account is allowed per ListenWIFI venue and installation. 

 

Ownership transfers are facilitated by providing a Venue Key to another user, allowing a new owner to import all system components of the venue to their account in another ListenWIFI Manager installation. See ‘Creating and Managing Venues’ section for additional details. 

 

Operator Account:  Operator accounts provide access to specific sections of the ListenWIFI Manager, allowing operators to manage the system day-to-day once system configuration is complete by the Owner.  These accounts only have access to the Checkout page for inventory management and the Mobile App page for branding customization.  Operator accounts do not have access to other pages or broader system configurations available to the Owner account.

 

Operator accounts are created by and associated to the Owner account as follows:

  1. Open the Owner Account profile window by clicking on the profile icon in the top right of the Manager software.
  2. Click the + icon next to ‘Manage Operators”
  3. Enter the name and email address for the desired operator’s account. Once complete, a blue + icon will appear to the right of the email address. 
  4. Click the + icon to save changes and add the operator. A temporary password is provided to be communicated to the Operator.

Operator accounts can be removed by clicking on the – icon to remove the user.

Creating and Managing Venues

A Venue is a collection of ListenWIFI system components in the Manager software, intended to function together as a cohesive system on a specific network.  System components are added and associated to the selected venue under the owner’s account.  A venue consists of the following items being added, specified, and/or customized: 

  • Wi-Fi Network (assign)
  • Wi-Fi Audio Servers (add)
  • Beacons (add)
  • Wi-Fi Audio Receivers (add)
  • Mobile Apps (customize)

Venue Setup 

The Venue Setup section guides you through setting up the venue, beginning with the assignment of a Wi-Fi network. Once the Wi-Fi network is specified on the Venue page, you can add and configure all components by visiting the respective pages for each ListenWIFI system component. Simply click on the component images in the Venue Setup section to navigate to their individual pages and add them to your venue.

As you add components, the Venue Setup section will automatically summarize the quantity and status of each component within the venue.

Naming your Venue

Upon creation, venues are automatically assigned a default name.  You can modify this name and give it a friendly name by clicking on the pencil icon to edit the name.

 

Assign the Wi-Fi Network

 To deploy ListenWiFi at your venue, start by specifying a wireless network on the Venue page:

  1. Enter Network Details: In the “Assigned Wi-Fi Network” section, input the SSID, security type, and password.
  2. Select from Available Networks: For convenience, a list of available wireless networks is provided below. Click on the desired network to automatically fill in the Network Name (SSID) field.
  3. Save the Network: Enter the password and save the wireless network to your venue.

This assigned Wi-Fi network will be used by all receivers added to the venue, as well as to create a Network QR Code for mobile app users. 

Network QR Code

Once the Wi-Fi network has been saved to the venue, a Network QR code is automatically generated on the Venue page. To print this QR code:

  1. Click on the “Print Network QR Code” button.
  2. Use the Windows printer dialogue box to properly size and print the QR code.

This QR code can be provided to mobile app users, allowing them to scan it with their smartphones to connect to the wireless network where ListenWIFI will be accessed. 

Managing Multiple Venues

The ListenWIFI Manager allows you to manage multiple venues from a single installation, making it easy to oversee various individual sites running ListenWIFI.

  • First Venue Creation: The first venue is automatically created upon your first login.
  • Adding New Venues: To create additional venues, click on the “+ Add new venue” option at the bottom left of the Venue page.
  • Switching Between Venues: You can select and toggle between venues using the venue selection drop-down at the top of the page.
  • Deleting a Venue: To delete a venue, click on the “—” icon within the venue selector at the top of the page.

Importing an Existing Venue

Venues are initially owned and associated with the original owner’s account (refer to the ‘Creating Accounts’ section). If ownership needs to be transferred to another account or computer, the venue can be imported using the Venue Key, a unique identifier for each venue.

To transfer ownership:

  1. Locate the Venue Key on the Venue page.
  2. Provide the Venue Key to the new account holder.
  3. The new account holder can import the venue by selecting the “Import an Existing Venue” option at the bottom left of the Venue page.

Please note, the Venue Key will automatically regenerate after a successful venue transfer. 

Adding and Managing Servers

Server Discovery:  From the Servers page, discover and add Wi-Fi Audio Server(s) to your venue.  The ListenWIFI Audio Server(s) should be powered on and connected to the same local area network as your computer running ListenWIFI. 

  • Servers are discovered automatically on the network and can be added to the venue by clicking on the blue add icon.

 

  • If your server(s) are not automatically discovered, it is possible that your network may block the automatic discovery protocol (mDNS). In this case, you will need to manually enter the IP address of the server in the manual discovery section and click the search icon.  Once found, click on the blue add icon to add it to the venue.  

Connection Status:  An active connection with ALL venue servers is required to make changes to a venue. The Manager indicates this connection status with all servers globally at the top of the page, showing either “Connected” or “Disconnected”. 

If the venue is reported as being Disconnected, ensure your computer is on the same local area network as the server(s). Also, make sure that all servers are powered on and connected to the network.  Once a venue is configured and changes are saved to all servers, the Manager does not need to remain connected and does not need to be open during use.   

Server Information

Simply click on any added server to open the server detail’s view.  The server detail’s view provides the following:

  • Server: The default server name which is only seen in the Manager.  Edit to give your server a friendly and identifiable name.
  • Model: The specific SKU of the server, including the channel count extension
  • ID: A unique 16-digit server ID
  • IP: The IPv4 address of the server on the network
  • MAC: The unique static MAC address of the server on the network
  • Version: The current firmware version installed on the server.  Simply click on the button to check for and install available updates. 
  • Mono/Stereo: The current input/channel configuration of the server.  Simply click on the button to toggle between mono and stereo operation.  Stereo uses 2 channel outputs to accommodate independent left and right audio channels.   

Mixer Configuration

Click on a server to open the server Mixer tab, which provides access to all channel configuration options:

Each audio input is associated to a specific channel to be streamed over the local area network to listening devices, including mobile phones and W-Fi audio receivers.  Each audio channel has the following configuration options available: 

 

Channel Name:  Name each channel as desired which will be displayed on listening devices.  

Channel Visibility:  Click on the eye icon to set channels to Hidden status (default is visible).  When a channel is set to Hidden, it will not be available or displayed on listening devices for manual selection, instead requiring a trigger to access the channel.  This trigger can occur using either beacons (automated access) or QR codes (manual access). 

Channel Password:  Click on the padlock icon to Password or PIN protect each channel.  When a channel is password/PIN protected, users will be required to input this password/PIN to access the channel.  The password/PIN protection can be applied to mobile apps only (where receivers automatically gain access), or to both mobile apps and receivers.   The specified Password/PIN will need to be communicated to ListenWIFI users who need to access the channel(s). 

PA Output:  Click on the announcement icon to assign a Public Address (PA) channel for the venue. When a PA channel is set, any audio detected on the associated input will temporarily be routed to all other channels for the duration of the audio presence.   Note that only one PA channel can be set per venue across all servers. 

Input Gain: Adjust the gain of each input as needed for proper level control.  Gain can be applied on each input in 6dB increments, up to a maximum of 24 dB of gain.

Input Delay:  Adjust the delay of each input as needed for proper alignment of audio to other sources, such as ambient sound, loudspeakers, video displays, etc.  Delay can be applied to each input up to a maximum of 3 seconds of delay.

Unused Inputs:  If you have extra channels that will not be used, simply drag and drop the channel inputs to the bottom of the screen to the “Unused Inputs” section.  This will disable those channels within the server, making them unavailable for listening purposes.  Channels can be reenabled at any time. 

Multilingual Channels

For rooms or spaces where multiple languages need to be made available, multiple inputs can be associated to the same output channel.  Simply drag and drop inputs onto a channel and then specify a language for each input using the drop-down selector. 

When accessing a multi-lingual channel, users will see a list of available languages to choose from. By utilizing the built-in language selector on both the mobile app and the Wi-Fi audio receiver, users can select any of the provided languages. The channel will automatically play in the user’s preferred language, based on the current language setting on their mobile app or receiver.

Network Configuration

Click on a server to open the server Network tab, which provides access to all network configuration options within the server: 

The ListenWIFI server is by default configured as a DHCP client, which means it will receive an IP address, subnet mask, gateway, and Domain Name Server (DNS) address automatically from the network it is plugged into.  If it is desired to configure the IPV4 settings directly on the server, click on the Servers page in the Manager software, click on the server and select the Network tab to specify these IPV4 settings (see image).

ListenWIFI audio packets are prioritized over other network traffic using Quality of Service (QoS) to ensure that ListenWIFI audio streams are sent over the network as quickly as possible, high priority, to ensure low latency for live audio applications. ListenWIFI audio packets are prioritized using a Type of Service (TOS) or Differentiated Services (DS) field, which is set to “0xB8” by default.  This field can be changed as needed depending on the network by editing the TOS/DS field. Typical values are 0xD8 or 0xB8 depending on the local network.  Some experimentation may be required to choose the optimal value.  

Additionally, the priority of the network traffic can be set based on the VLAN priority of either Voice or Video.  The default value of “Voice” is recommended but can be changed to Video if it provides a better experience on your network with lower latency and less dropouts. Some experimentation may be required to choose the optimal value.

Adding and Managing Beacons

Adding Beacons

Beacons must first be added to a ListenWIFI venue in the Manager before they can be configured.  Beacons can be added in one of 2 ways:

  • USB Connection (recommended): Simply plug in the beacon to the Manager computer.  The beacon will automatically be added to the venue.
  • Bluetooth Connection: With Bluetooth enabled on the Manager PC, powered-on beacons within range can be discovered wirelessly. These beacons will appear at the bottom of the beacon section, marked with a blue “+” icon if they are available to be added to a venue (i.e., not already owned or associated with another venue). To add an available beacon to the venue, simply click the blue “+” icon next to it.

Beacon Connection

To connect to an added beacon for configuration, simply click on it. If the beacon is connected via USB, configuration options will appear immediately. If the beacon is not connected via USB, the Manager PC will attempt to establish communication with the beacon via Bluetooth. Once connected, the beacon information and configuration parameters will be shown to the right.   

 

 

 

Beacon Information

Click on any added beacon to open the beacon detail’s view.  The beacon detail’s view provides the following:

  • Infrared Power – Adjust the effective range of the beacon for receivers. Can be set to Low, Medium, or High (see Beacon Range table).
  • Transmit Interval – Adjusts how often the beacon signal is broadcast. Adjustable from 300mS up to 5 seconds (default 1 second).  A faster interval allows for a more responsive trigger from listening devices but increases the power consumption. 
  • LED Indicators – Enable/disable the blue status LED flash every 5 seconds shown during normal operation. Default is enabled. 
  • Low Battery LED – Enable/disable the red status LED flash every 5 seconds shown when batteries are low. Default is enabled. 
  • OTA Configuration – Enable/disable the over-the-air (OTA) connection method for configuration. When disabled, the device cannot be connected to via Bluetooth for configuration and must be directly connected via USB. 

Adding and Managing Receivers

Adding Receivers

Prior to use, receivers must first be plugged into the Manager PC where they are automatically added to the ListenWIFI venue.  Receivers can be plugged into the Manager PC using either a direct USB cable, or via a ListenWIFI Docking Station.  Once added to the venue, receivers are automatically provided with the Wi-Fi Network credentials for that venue and given the “Venue Default” profile.

 

Receiver Inventory

All receivers added to the venue will be displayed in the Manager software, regardless of their current connection or power status. The Manager software categorizes all venue receivers into the following states:

  • Docked: Receivers connected via a docking station.
  • Connected: Receivers that are powered on and connected to the Wi-Fi network, including those connected via USB.
  • Disconnected: Receivers that are powered off or disconnected from the Wi-Fi network.”

Receiver Profiles

Receiver profiles are collections of settings that can be saved and loaded into receivers. This feature allows you to create and manage multiple profiles, enabling quick changes to receiver settings based on the desired user experience or specific events. Profiles can be applied to individual receivers or groups, providing flexibility and ease of management.

By default, all newly added receivers will be assigned to the ‘Venue Default’ profile but can be reassigned to a different profile at any time.

Profiles can be selected from the Receiver page by clicking on the profile name towards the top. When a profile is selected, it will highlight all receivers assigned to that profile. Additionally, clicking on any individual receiver will automatically select that profile and all assigned units. This allows receiver settings to be easily managed as part of their group, without needing to apply individual changes, providing ease of receiver management.

Creating Profiles:   

To create a new profile, follow these steps:

  1. Click on the “Create New Profile” icon.
  2. Assign a friendly name to your profile. This name will be displayed on the receiver’s home screen during bootup and operation.
  3. Select a color for the profile by using the color selector. Colors help quickly identify different profiles.
  4. Set unit preferences for the profile from the Settings
  5. Configure automations for the profile from the Beacons

 

Profile Configuration

Each profile includes configuration options that can be customized as follows: 

Profile Name

Assign a user-friendly name to a profile by modifying the default name. This makes it easy to identify in the Manager software and directly on the receiver’s display. The receiver shows the profile name when connected to the docking station or USB power, during bootup, and when the display is first turned on.

Profile Color

Set a unique color for your profile by clicking on the colored square next to the profile name.  Each receiver assigned to this profile will be shown in this color for easy tracking and management within the Manager software.

  • Brightness:Adjust the display brightness, choosing between OFF, Dim, Bright, and Auto (default).
  • Auto Off:Set the auto-off time for the receiver to power off automatically after a period of audio silence. Options are 10, 20, or 30 minutes (default), or disabled.
  • Jack Sense:Enable the receiver to automatically power on when a headphone jack is inserted and power off when disconnected. Enabled by default.
  • Auto Power:Enable the receiver to automatically power on when removed from the charger and power down when connected to the charger. Enabled by default.

Beacons Tab   

To configure beacon automations for the receiver profile, simply click on the ‘Beacons’ tab. You can subscribe to specific beacons and program them to trigger a specific channel when the beacon is detected by the receiver.

  1. Select the beacon(s) you want the receivers to monitor.
  2. Use the channel selector drop-down to choose the channel that will play when the beacon is detected.
  3. Decide whether the audio should continue playing or disconnect when the receiver leaves the beacon’s range by enabling or disabling the Exit Timeout. The timeout value can be set from 10 seconds to 10 minutes, or it can be disabled (default).

Assigning Profiles

Profiles can be loaded into receivers as follows: 

  1. Click and hold the profile name.

 

  1. Drag and drop the profile name onto an individual receiver as shown.

 

Tip:  You can drag and drop the profile name to the virtual docking stations “Clone Button” to  apply the profile to ALL receivers in a dock. 

Receivers must be in a ‘Connected’ state (via Wi-Fi, USB, or Docking Station) to accept new profiles. When editing existing profiles already assigned to receivers, those receivers will automatically receive the profile updates, even if they are in a disconnected state. 

Receiver Information

Click on a receiver’s gear wheel to view receivers detailed information, including the following:

  • Unit ID: Receivers 4-digit identifier displayed on the unit and in the Manager software.  Assigned by default and can be edited as needed. 
  • Battery: Indicates the current battery level. 
  • Firmware: The current firmware version installed on the receiver.  Simply click on the button to check for and install available updates. 
  • Model: The specific model # or receiver SKU

You can copy the serial, MAC, and IP address of a receiver to the clipboard by left clicking on the copy icon. Right-clicking will copy this information for all receivers. This data can then be pasted into a Word document or Notepad for IT staff or network administrators.

System Updates

ListenWIFI Manager software will automatically check for available software updates upon app launch.  It is recommended that the Manager software be updated first, prior to any available ListenWIFI component updates.  This will ensure compatibility, best performance and access to the latest features. 

ListenWIFI system components, including Wi-Fi Audio Servers, Beacons, and Wi-Fi Audio Receivers, will occasionally have available firmware updates available.  It is important to keep all your ListenWIFI system components up to date to ensure the latest feature set as well as compatibility with the latest smartphones and operating systems.   To check for available firmware updates, navigate to each system component in the ListenWIFI Manager software and click on the device to view the firmware update button which displays the current firmware version (see image below).  Simply click on the firmware version button to automatically check for available updates and follow the prompts to update. 

Updates should be applied at a convenient time when the ListenWIFI assistive listening system is not being actively used, as system components will not be operational during their updates process. 

Security

Security is of utmost importance for any device that resides on your network. A single vulnerable device can compromise the security of your entire network, leading to data breaches, malware infections, and other cybersecurity threats. The ListenWIFI products, including Wi-Fi audio servers, receivers, mobile apps, and management software have been hardened against security threats and vulnerabilities to ensure that the risk of unauthorized access is minimized, and your network remains protected. Maintaining network security is an ongoing process that requires regular monitoring, updates, and proactive measures to stay ahead of evolving threats.  We are continually monitoring and identifying potential threats and vulnerabilities, subsequently pushing out software updates and patches to address those that could impact ListenWIFI.  Therefore, we highly recommend keeping your software up to date on your ListenWIFI servers and products deployed on your network. 

System hardening is a continuous effort on ListenWIFI to reduce the attack surface of system components, providing significantly improved security, functionality, and product performance.  The following highlights some of the system hardening efforts that have been implemented on the ListenWIFI product platform to ensure our system remains both secure and reliable: 

  • Software and Operating systems are updated and patched when vulnerabilities are discovered.
  • Encryption of all data at all times, regardless of configuration.
  • Data transmission is contained to the Local Area Network (LAN), and never sent over the internet.
  • Only very low-sensitivity data is stored on the ListenWIFI servers and is encrypted.
  • HTTPS endpoint communications between servers and listening devices is limited to basic data transmittal to start/stop UDP audio streams and exchange basic visual assets.
  • Access Controls implemented allowing only authorized accounts access to management software and controls.
  • 3rd party security audits are completed to ensure threats are addressed.

 

The security of ListenWIFI will also be dependent on your network architecture and implementation.  For the best security and performance on your network, we do recommend that you place your Wi-Fi audio server on the same network that your listening devices will connect to, and simply whitelist communication to the server with client isolation implemented as applicable. This deployment will typically allow the required communication to occur between devices without having to modify your router or firewall rules and prohibits any unnecessary communications between client devices.  Alternatively, the server and listening devices can be placed on separate networks, however the proper ports must be opened and the ListenWIFI traffic must be routable which can increase network vulnerabilities.  Please reference our Network Configuration Guide for more details.

If you have questions or would like to review your deployment of ListenWIFI on your network, please reach out to one of our team members at Listen Technologies Corporation.
