Williams AV IR SY4 IR RX20 Infrared Transmitter System

The Williams AV IR SY4 IR RX20 Infrared Transmitter System features Stethoset receivers. It is an update on WIR SYS 7518 PRO.

The IR T2 transmitter is a commercial-grade, medium-area infrared transmitter for accessible audio. The IR T2’s sleek, compact footprint is ideal for assistive listening and language interpretation in commercial spaces such as conference rooms, assisted living facilities, small cinema/theaters, classrooms and courtrooms. The new IR T2 infrared transmitter offers 50 percent greater coverage than the previous IR device (WIR TX75) and new control system readiness — all at a more affordable price. With a significantly wider coverage pattern and more power, there is no need for the additional expense of secondary units.
