Product Overview

The Listen LT-82 is the heart of a stationary IR listening system.
It takes the desired audio signal and transmits the signal via coaxial cable to one (1) or more IR radiator-emitters (LA-140).

Includes:

  • LT-82 Stationary IR Transmitter
  • LA-205 30 VDC Extension/Replacement Power Supply
    for LA-140/LT-82
  • LA-89 Interconnection Coaxial Cable
  • Quick Reference Card

Applications

The LT-82 can be operated in mono or stereo on one (1)
of four (4) different carriers; up to four (4) LT-82 units may be connected to provide up to four (4) mono or stereo carriers
to the radiators and generates DC power to power up to two (2) LA-140 radiator-emitters.

Two (2) 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
