This large-area infrared listening system is designed for environments where audio must remain private, stable, and fully contained within the room. By using infrared light instead of RF or Wi-Fi, it delivers secure audio distribution without spillover into adjacent spaces.
Built around a Dante-enabled infrared modulator and a multi-emitter array, this system is well-suited for courtrooms, government facilities, large conference rooms, and other professional environments that require predictable coverage and clean AV integration.

The Williams AV Large-Area Infrared Listening System uses infrared transmission to deliver clear audio that stays inside the space where it is intended.
Because infrared signals do not pass through walls, the system is ideal for facilities where confidentiality, interference control, or room separation is critical.
At the center of the system is the IR M1 D infrared modulator, which accepts Dante audio directly from a networked AV system. This allows seamless integration with modern digital audio infrastructures without additional converters or analog cabling. Audio is distributed through an emitter array designed to provide even coverage across large rooms.
Listeners use bodypack infrared receivers that require no pairing, tuning, or network access. Once powered on, receivers automatically pick up the infrared signal, making the system easy to manage even in high-turnover or public-facing environments.

Infrared listening systems keep audio contained within the room. For large spaces with sensitive discussions or nearby rooms using audio systems, infrared prevents signal overlap and unintended listening.
The emitter array allows infrared signals to be distributed evenly across wide spaces. This helps avoid dead zones and ensures listeners receive consistent audio throughout the room.
Dante allows audio to be sent directly from a digital AV network to the infrared modulator. This simplifies installation and reduces the need for analog adapters or additional signal processing.
Yes. Infrared systems require proper emitter placement to maintain coverage. When installed correctly, the array ensures a reliable signal throughout the listening area.
Yes. The system supports adding more bodypack receivers at any time without modifying the core infrastructure.
It can be used in interpretation setups when paired with appropriate audio sources, but it is most commonly deployed for secure, single-language assistive listening in large rooms.
Yes. When installed properly, the system meets 2010 ADA assistive listening requirements and includes compatible receivers, earphones, and required signage.
