Listen Technologies LT-803-072-P1 Stationary 3-Channel RF Transmitter Package 1

Built around Listen's LT803-072 RF transmitter, the LT-803-072-P1 start-up transmitter package will allow you to offer assistive listening to your guests right away.

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.

You'll also get the LA-106 extended range telescoping antenna that mounts directly to your transmitter making sure the signal goes out loud and clear. Plus, a notification signage kit is included to provide awareness and ensure compliance.

This package operates in the 72 MHz frequency range only and does not include receivers or hearing devices, they must be purchased separately.
