Williams Sound IR T1 Overview

The Williams Sound IR T1 is a dual-channel, infrared base transmitter designed for assistive listening in small areas. It is compatible with the WIR RX22-4 and WIR RX18 receivers and is well-suited for private TV listening in conference rooms, hospital rooms, assisted-living facilities, medical treatment centers, jury deliberation rooms, and more.

Easy to set up, the IR T1 features an 1/8" input jack that accepts any line level stereo audio. The operating frequencies (2.3/2.8 MHz) minimize high-efficiency lighting interference for a clear sound and provide a coverage area up to 1000 ft².

Three LEDs display power status and audio input strength. If a minimum acceptable audio level is not present on a channel, after twelve minutes that channel will automatically go into sleep/power-save mode to decrease power consumption by 80%.

The IR T1 can be mounted on any camera tripod stand with a 1/4"-20 threaded connector. It ships with a power supply and USB power cable, an 1/8" stereo audio cable, and an adapter cable for use with a TV equipped with an RCA audio output.
