LT-800 57-Channel Stationary Transmitter

The Listen LT-800 Stationary Transmitter can be used in a variety of applications.
Language interpretation (including multiple simultaneous interpretations) can utilize a sound booth (a separate area or room where the interpreter can speak and not disturb the rest of the audience), and broadcast the interpretation to individual receivers up to 3,000 feet away.

We have the  LT-800 Stationary Transmitter available for rent in the 216MHz frequency range, with 57 channels.  This means you are sure to find a clear signal, or can use up to three Listen LT-800 Stationary Transmitters in the same area (up to three languages for simultaneous interpretation).

The LT-800 can also be connected to your main audio system, then broadcast that high quality audio signal to belt pack receivers, stationary receivers, or wireless speaker/receivers. Remote amplification can be achieved using the LT-800 and Listen's LR-100 Stationary Receiver/Power Amplifier or LR-600 Wireless Speaker Receiver.

The LT-800 also supplies two mixing audio inputs. Installation of the stationary transmitter can also be aided by a "test tone" transmitting from the unit.

The LT -800 can be rack mounted with other audio equipment, or set on a shelf. A complete line of antennas is also available from Listen.
