ListenIR System Overview

Transmitters

The infrared transmitter transmits your audio signal to and provides the power for one or more radiators/emitters.

Radiators

Radiators provide reliable infrared signals and can be combined and powered by a single transmitter.

Receivers

Infrared receivers receive the signal and deliver sound directly to the listener's ear while filtering ambient noise for superior intelligibility and sound.

Accessories

From signage to headphones, to cable management, accessories enhance the functionality of your infrared assistive listening system.

Transmitter/Radiator

The ListenIR transmitter/radiator combo transmits a clear, reliable signal across large areas. The signal range ensures that users in any sized space, from the boardroom to the courtroom and beyond, enjoy an uninterrupted audio performance.

Transmitters can be added to an audio rack or mounted on a wall with included mounting hardware.

Multiple frequency options offer additional flexibility and simplicity during installation and setup. 

ListenIR is the first infrared assistive listening system to feature expansion radiators, which provide delay compensation to ensure that there are no signal cancellation dropouts. When combining a transmitter with extension transmitters, signal timing features eliminate delayed audio signals. Everyone hears the same message at the same time. 

ListenIR transmitters have a small profile and are unobtrusive in any environment.

As innovators in assistive listening technology, our patent sets our infrared technology apart as unique. Your guests deserve the best and that's exactly what you get with ListenIR.  The ListenIR LT-84 (ListenIR 2-Channel Transmitter/Radiator Combo) and LA-141 (ListenIR Expansion Radiator) are covered by US Patent 9,712,246.

Radiators

ListenIR radiators deliver twice the IR power and up to six times the coverage area of similar products. This provides extensive, reliable coverage for a better experience.

Several patented design elements provide twice the infrared power and up to six times the coverage area of similar products. With this patented technology, ListenIR outperforms any other infrared technology in the market.

Expansion radiators can be added to the system to provide additional coverage up to 12,192 2,787 square meters (40,000 square feet). The only product of its kind that provides complete, gapless coverage.

ListenIR radiators deliver twice the infrared power for a superior coverage area. Most infrared systems on the market today suffer from audio dead zones where the audio cannot be detected. ListenIR offers the best coverage in the industry.

Receivers

ListenIR receivers are small and lightweight and can be used with ear speakers, earbuds, or neck loops.

Two Listen Technologies Infrared Receivers in two different modes: Lecture and Courtroom.

ListenIR receivers are constructed with low loss, impact resistant, infrared transparent material which allows the receiver to pick up infrared light from all directions for the best reception.

ListenIR receivers have a micro-USB port for charging and programming the receivers with free software from Listen Technologies.

Extended speaking sessions, classes, and hearings can be challenging for other devices, but ListenIR receivers incorporate advanced rechargeable batteries that offer long life and reliable power.

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.

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

Accessories

Accessories complement every application by adding functionality and features to customize your system based on the needs of your environment.

Full Case Study
We brought in key potential users of the system to hear how it sounded, and test how easy it was to use. All were very impressed with the quality of the ListenIR system.
Danny Conn Hult Center for the Performing Arts, Head Audio Engineer
We use the ListenIR systems for both assistive listening and language interpretation. The system works really well for us, because we have lots of diverse groups including senior citizens who need assistive listening, as well as groups who need an interpretation system. We can have an interpreter anywhere, providing language interpretation services for a meeting and the interpretation can be heard in multiple rooms. Assistive listening can be provided for single or multiple rooms and everything can be combined. It’s really versatile and very useful.
Jay Clark Davis Conference Center, AV Manager
The digital transmitter offers excellent coverage, and the intelligibility and clarity of the speech is exceptional. Also, the audio fidelity is phenomenal both for speech and for prerecorded material such as music. When the client heard it, they were blown away. We knew they would be.
