IR T2 SoundPlus® Medium-area Infrared Transmitter


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 device has replaced the now discontinued WIR TX75.
