Listen Technologies LT-803-072-01 Stationary 3-Channel RF Transmitter, 72MHz

Communication is all about being clear, the LT803 is a great communicator.

Able to transmit on 57 channels to beltpacks, stationary receivers or wireless speaker receivers, the LT803 was designed for applications where one to three channels of audio is required.

Universal inputs give you the flexibility to use mixers, microphones, handheld devices, and more as your audio source while an internal auto processor optimizes the signal for transmission to ensure superior audio quality.

Channel status, selection, and programming can be monitored at a glance via the front panel LCD display. There's even a VU level meter with a test tone so you can dial in the correct levels to avoid noise and distortion.

Make sure they hear everything, make sure it comes from the LT803.

The LT803-072 transmits only in the 72 MHz frequency range.

Features:

• Three channels - makes it simple to instal, manage and use
