Share

Thanks to its outstanding audio quality, the Listen Technologies LT-800 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 beltpack receivers, stationary receivers, or wireless speakers / receivers. The end result—your audience can hear and understand the presentation better because of improved speaker placement or because they have their own beltpack and headset. The signature Look & Listen™ LCD shows channel, lock, programming and RF power. Available in 72 or 216 MHz options. Please select preferred frequency when ordering.
