Operating at 72 MHz, the Stationary RF Transmitter Package from Listen Technologies can be used in a variety of assisted-listening applications, broadcasting signal from your particular audio system to a belt-pack or stationary receiver. This model comes pre-packaged with an LA-106 Telescoping Top-Mounted Antenna and an LA-304 Assistive Listening Notification Signage Kit to facilitate communication between you and your audience, whoever they happen to be. With its 80 dB signal-to-noise ratio, it provides intelligible audio across 57 selectable channels, all digitally tuned so that your transmissions won't drift. Up to eight channels can be used simultaneously on the 72 MHz frequency with multiple transmitters.

The transmitter's Look & Listen LCD displays channel, lock, programming, and RF power, while balanced and unbalanced inputs allow you to connect with a variety of audio sources. The transmitter is rack-mountable and features auto-processing to make the audio clearer for audible transmission. To make the unit easier to set up and install, a VU level meter and test tone generator are included.
