w/ 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 which is included in w/ Dante variant only. The LT-82, which may function in mono or stereo modes, transfers your audio signal to one or more LA-140 infrared radiator/emitter devices and supplies DC power for them using a typical CAT-5 connection. 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.
