Small Area Infrared Transmitter


The IR T1 is a two-channel small area infrared transmitter combining infrared modulator and emitter technology into a single mountable enclosure—which reduces operating costs, eliminates the need for rack space and eases set-up.

The IR T1 is ideal for high quality audio programs such as music, television audio, and audio description. The IR T1 will accept any line level stereo audio input. Infrared receivers detect the transmission and convert the light signals back into audio signals. The IR T1 operating frequencies (2.3/2.8 MHz) minimize high efficiency lighting interference.

No FCC license or radio approval is required with this equipment. It can be used anywhere in the world.
