  • ListenIR LT-82 1-Channel Transmitter

    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

There are included mounting brackets for mounting the radiator to the wall or ceiling, or to a desk, mic stand, or tripod. Power can be supplied through the transmitter or through a separate power supply. Built-in delay compensation prevents signal cancellation and eliminates the need for additional cabling. The Stationary IR Radiator covers up to 10,000 ft², and features delay compensation, ensuring no drop out in the IR signal.

    Covers up to 10,000 ft² / 929 m²
    Two radiators can be powered from a single transmitter or optional power supply, eliminating the need for multiple cables
    Mounting brackets included for multiple mounting options, including wall, ceiling, mic stand and tripod mounting hardware
    Units can be horizontally or vertically mounted together, doubling the power in a small footprint
    Radiator diodes are automatically turned off if no audio signal is present at the transmitter after 30 minutes, saving radiator diode life
    Delay compensation ensures there is no drop out in the IR signal
