Details
The Listen Tech LT-82 Stationary IR Transmitter is the heart of a stationary IR listening system. It takes the desired audio signal and transmits the signal via coaxial cable to one or more IR radiator-emitters (LA-140). The LT-82 can be operated in mono or stereo on one of four different carriers; up to four LT-82 units may be connected to provide up to four mono or stereo carriers to the radiator(s). The LT-82 generates DC power to power up to two LA-140 radiator-emitters. Two LT-82 units can be rack mounted in a single rack space using the LA-326 rack mounting kit. The LT-82 is used for government compliance (such as ADA), assistive listening, language interpretation, live theatre, houses of worship, courtrooms, secure rooms and for auditory description.

Features
- Secure wireless communication - ideal for applications where isolation of the signal is important
- Up to four channels mono, or four channels stereo - no need to sacrifice multiple channels to achieve stereo transmissions (one LT-82 is required for each channel)
- Transmitter can power two radiator/emitters (LA-140) using CAT-5 cabling
- Easy to specify, install and use
- Outstanding performance - ensures crystal clear sound for listeners
- Limited Lifetime Warranty
- True stereo audio (left and right) is transmitted on a single carrier frequency
