W-IR T2 medium-area IR transmitter

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.

Includes mounting hardware W-BKT 024

This device has replaced the WIR TX75.

Code: W-IR T2
