Listen Technologies ListenIR 1-Channel Transmitter (Dante) - LT-82-01-D

Description

ListenIR 1-Channel Transmitter (Dante)

The heart of the Listen Technologies ListenIR system is the LT-82 single-channel transmitter, Dante compatible through the use of the LA-465 Dante adapter. 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.

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.
