The heart of the Listen Technologies ListenIR system is the LT-82 single-channel transmitter. Capable of operating in either mono or stereo modes, the LT-82 transmits your audio signal to and provides DC power for one or more LA-140 infrared radiator/emitter units through a standard CAT-5 cable. Plus, units can be combined to offer up to four (4) channels of mono or stereo audio for expanded applications.
Easy to install and backed by a limited lifetime warranty, the LT-82 transmitter is an ideal infrared transmitter for a wide range of assistive listening needs, including theaters, houses of worship, language interpretation, and more.
