Williams AV IR T2 soundplus medium-area infrared transmitter

General Description

The Williams AV IR T2 is a compact infrared transmitter to cover medium size rooms. The transmitter has an integrated modulator enabling audio sources to be connected direct. The audio is then transmitted via infrared light. 

The IR T2 features two balanced line level inputs via Euroblock connectors and a 3.5mm jack socket for the connection for a microphone, which can be adjusted using the dedicated mic gain knob. A channel selection button is used to choose transmission on 2.3 and 2.8MHz or 3.3 and 3.8MHz.

Its sleek, compact footprint is ideal for assistive listening and language interpretation in commercial spaces such as conference rooms, assisted living facilities, small cinema/theatres, classrooms and courtrooms.
