Williams AV IR SY6 Portable Infrared Courtroom System

A portable system specifically for courtrooms featuring the IR T2 infrared transmitter.

The IR T2 is a 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.
