Description
This LT-82 1-Channel Transmitter from Listen Technologies takes the desired audio signal and transmits the signal via coaxial cable to one or more LA-140 IR radiator-emitters. The LT-82 can be operated in mono or stereo on one of four different carriers, and 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 may be used for government compliance (such as ADA), assistive listening, language interpretation, live theater, houses of worship, courtrooms, secure rooms, and for auditory description.
- Secure wireless communication, suitable for applications where isolation of the signal is important
- Up to four mono or stereo channels; no need to sacrifice multiple channels to achieve stereo transmissions (one LT-82 is required for each channel)
- Transmitter can power two radiators/emitters (LA-140), using Cat5 cabling
- Easy to specify, install, and use
- Performance ensures clear sound for listeners
- True stereo audio (left and right) is transmitted on a single carrier frequency
