The 72 MHz Performance RF System from Listen Technologies is a complete assistive listening system that includes one Listen Technologies Stationary RF Transmitter, one Universal Antenna Kit, one Universal Rack Mounting Kit, four Portable Display RF Receivers, four Ear Speakers, eight high-capacity AA Alkaline batteries, and one Assistive Listening Notification Signage Kit.

  • Stationary RF Transmitter (72 MHz)

    Operating at 72 MHz, the Stationary RF Transmitter from Listen Technologies can be used in a variety of applications, broadcasting signal from your particular audio system to a belt-pack or stationary receiver. 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.
