ListenRF System Overview


Transmitters are connected to the audio source or sources and send the radio frequency signal to the antenna.


The ListenRF antenna transmits the signal over radio frequency to individual receivers.


Receivers are tuned to the radio frequency channel to receive and deliver the audio directly to the listener's ear while filtering ambient noise.


Listen offers a variety of headsets and an integrated neck loop that offer crisp, clear sound and intelligibility.


ListenRF transmitters offer outstanding audio clarity, digital signal strength meter, and shows status information for channel selection and programming. Connected to your main audio system, transmitters broadcast the audio over 72 MHz or 216 MHz.

Balanced and unbalanced audio inputs allow use with any audio source.

Built-In Audio Processor

The built-in audio processor optimizes audio (voice or music) prior to transmission.

SQ Mode for Exceptional Sound

The SQ (super quiet) mode on ListenRF transmitters removes audio hiss for exceptional sound. 


Antennas are a vital part of a radio frequency system. Listen offers a complete line of transmitter antennas based on space, coverage area required, and indoor or outdoor use.

Small Spaces
Small spaces require minimal coverage that is typically handled by an entry-level antenna. The transmitter is locally installed within or adjacent to the room and running a coaxial cable to the antenna is not necessary. The transmitter may also be setup as a portable system that is moved from room-to-room when needed.
Medium to Large Spaces
Medium to larger spaces have a larger coverage area and the transmitter is generally located in a rack room away from the space that requires coverage. It is necessary to run a coaxial cable from the transmitter to the antenna so it can be mounted within the space and/or higher to provide adequate coverage; this is referred to as a “remote mounted” antenna.
Outdoor Spaces

Outdoor spaces are commonly large venues that can hold a large number of people. The transmitter is not designed for outdoor use, so it will be installed indoors, such as in a rack room. The weather grade remote antenna is then mounted outdoors within the coverage area.


ListenRF receivers use intelligent Digital Signal Processing (iDSP) making them the best in the industry. All receivers offer outstanding audio clarity with the best ranges and reception.

Listen RF Receiver with Stadium written on it
iDSP for Superior Audio

Intelligent Digital Signal Processing (iDSP) means the receiver provides digital quality audio for superior sound quality vs. lower quality analog audio. Plus, you can set up and manage receivers using the free iDSP software.

Small and Discreet

Listen offers the smallest devices in the market which makes them lightweight and easy to wear. The small size also makes their use more discreet for users that are conscientious about using assistive listening devices.

Micro-USB Connection

Each receiver is equipped with a micro-USB connection which can be used with free iDSP software for charging, set up, programming, inventory management, and firmware updates.

Long Battery Life

Extended use can be challenging for other devices, but Listen receivers incorporate advanced Lithium-ion rechargeable batteries that offer long life and reliable power. Receivers can be charged with the micro-USB connector or in the docking station. 

Integrated Neck Loop

The neck loop is a reliable and effective way for listeners with telecoil-equipped hearing aids and cochlear implants to utilize your assistive listening system.

See the Integrated Neck Loop

Intelligent Ear Phone/Neck Loop Lanyard

Each neck loop slips comfortably over the wearer’s neck and transmits the audio signal wirelessly to their t-coil device or cochlear implant, leaving the user’s hands free for added convenience.

Advanced DSP Loop Driver

Incorporating an advanced digital signal processing (DSP) loop driver for an outstanding listening experience, the integrated neck loop provides industry-leading assistive listening.

It is great to see products successfully installed in one of the biggest and best AV installations in the world.
Frank Frombach SurgeX, Regional Sales Manager
After the High Holy Days, we checked in with Judi to see how the Listen systems had worked – she said that there were several congregants for whom it made a huge difference, and she even got a letter from one who had been part of the congregation for decades, and said that this is the first time she’s been able to really hear the service. And it was an easy installation – we basically got the system configured and handed it over to them. Plug and play!
