Listen Technologies LT-800-216-01 Stationary RF Transmitter

Thanks to its outstanding audio quality, the Listen Technologies LT-800-216-01 Stationary RF Transmitter can be used in a variety of applications. The LT-800 is connected to your main audio system, broadcasting a high quality audio signal to belt pack receivers, stationary receivers, or wireless speaker / receivers. The end result, your audience can hear and understand the presentation better because of improved speaker placement or because they have their own belt pack and headset. The signature Look & Listen LCD shows channel, lock, programming and RF power.
