SoundPlus® Medium-area Infrared (IR T2) System IR SY6

Williams Sound

Portable Infrared ADA Compliance Kit for Courts

Building on years of infrared audio delivery expertise, Williams Sound is pleased to introduce the new SoundPlus® IR T2 commercial-grade, medium-area infrared transmitter. Its 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 75P PRO.

Please call for the availability of this system.
