This medium-area infrared listening system is designed for venues that need secure, room-contained audio with professional AV integration, without the scale or complexity of a full large-area deployment.
It delivers consistent infrared coverage using a Dante-enabled modulator and an emitter array optimized for mid-to-large rooms. The system is ideal for courtrooms, council chambers, lecture halls, and conference rooms where privacy, reliability, and clean audio routing are essential.

The Williams AV Medium-Area Infrared Listening System uses infrared light to transmit audio that stays confined to the room.
Unlike FM or Wi-Fi systems, infrared signals do not pass through walls, making this solution well-suited for environments with sensitive audio or adjacent spaces using other listening systems.
At the center of the system is the IR M1 D infrared modulator with Dante input. This allows audio to be delivered directly from a Dante-enabled AV network without additional converters or signal processing hardware. The modulator feeds an emitter array that distributes infrared audio evenly across the listening area.
Listeners use WIR RX22-4N bodypack receivers paired with earphones. Receivers require no pairing or tuning, making them easy to distribute and manage in public or shared environments.

The IR SY21 D is designed for medium to moderately large rooms and uses fewer emitters. It provides the same infrared security and Dante integration, but with a smaller coverage footprint.
Infrared listening systems like the IR SYS21 D keep audio inside the room. This prevents signal leakage, reduces interference, and supports confidential discussions in shared or multi-room facilities.
Yes. Infrared systems rely on proper emitter placement. The included array helps ensure consistent coverage when installed correctly.
No. Users simply turn on the receiver and adjust the volume. There is no pairing, channel selection, or network connection required.
Yes. Additional WIR RX22-4N receivers can be added at any time to support more listeners without changing the core system.
Dante allows audio to be delivered digitally over Ethernet from existing AV systems, reducing cabling complexity and eliminating analog signal conversion.
Yes. When installed correctly, this infrared listening system meets 2010 ADA assistive listening requirements and includes required signage.
