Williams AV IR SY4 Medium-Area Infrared System with Stethoset Receivers

The IR T2 is a commercial-grade, medium-area infrared transmitter for accessible audio. This system features Stethoset receivers.

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.

This system has replaced the now discontinued WIR SYS 7518 PRO.
