Product Overview:
Listen’s LR-100 Stationary RF Receiver/Power Amplifier is a stationary auditory assistance receiver with a built-in power
amplifier. When used with a Listen transmitter, the LR-100 can deliver high quality audio for use in a variety of locations and
applications — most commonly with a wireless audio distributed system. This unit has Listen’s signature Look&ListenTM LCD
Display showing channel, lock, and battery level. A security cover protects auxiliary and receiver volume, adjustable squelch
and trim controls. It has an balanced or unbalanced speaker wire output options. Multiple input options give this unit great
flexibility. It’s powered by a 15 VAC/1000mA power input or 12 VDC battery. An antenna is needed for reception.
Highlights:
Superior audio quality – 80 dB signal-to-noise ratio (SNR), setting the industry’s sound quality standard
57 channels
100 % Digital – Listen receivers are digitally-tuned so the transmission won’t drift
Programmability – Unneeded channels can be locked so this receiver will access only one or more channels of your
choice
Look & Listen™ LCD shows channel, battery status, signal strength and programming information
Uses standard alkaline or nickel-metal hydride (NiMH) batteries
Built in SmartCharge™ won’t allow batteries to overcharge. Charging circuitry is conveniently built into Listen’s
receivers
Drop in charging contacts for any of Listen’s many charging cases or a charging plug on the side of the unit
Adjustable squelch control
Selectable audio output
Multiple input options
Remote control capabilities
Optional 12 VDC input
Many accessory options make Listen products ideal for a wide range of applications
