Listen Stationary IR System

There are three main components involved in the Listen Stationary IR system:

Receiver(s)

The IR light from the radiators is detected by the receivers and turned into sound. Listen offers the LR-42 stethoscope and LR-44 lanyard style receivers. The stethoscope is an “all-in-one” unit, making it easy to keep track of checked out equipment. The lanyard receiver accepts any style of 3.5 mm earphone, giving users more choices.

Radiator(s)/Emitter(s)

The radiator transforms the RF audio signal from the LT-82 transmitters into an IR signal. This is essentially a “headlight” that illuminates the room with non-visible IR light. The size and shape of the room will determine how many radiators or “headlights” you’ll need to fill the room for adequate signal coverage. It’s powered by either the LT-82 transmitter or an LA-205 extension/replacement power supply. Hardware for most types of mounting configurations, comes standard with each radiator, and the radiator is available in two colors; grey or white.

Highlights

•Simple to specify, install, maintain, and use.

•Secure – the signal will not leave the room.

•Up to four simultaneous mono or stereo channels allows for expanded applications.

•Uses higher modulation (2.3 to 3.8MHz) frequencies thereby decreasing the risk of light interference from fluorescent lights and other sources.

•Installation is simple using CAT-5 cables for power distribution.

•The radiator mounting hardware is included with each radiator.

•Users will enjoy the simple but refined look and feel of both the stetho and

lanyard receivers.

•Advanced battery management ensures long battery life.

•Uses standard AAA alkaline batteries or an optional rechargeable pack (LA-364).

•Compatible with other manufacturers.

•Limited lifetime warranty (radiator – 3 years and accessories 90 days).

Transmitter(s)

The LT-82 Stationary IR Transmitter accepts audio from an audio mixing console or other sources. It then turns this audio signal into an RF signal and delivers it to an LA-140 radiator via coaxial cable. The LT-82 also provides DC power for up to two LA-140 radiators via standard CAT-5 cabling. For a single channel system (mono or stereo) use one LT-82. Add more channels (up to 4 total) by adding more LT-82 units.

Two cables connect the LT-82 Transmitter to the radiator(s). CAT-5 cable is used for power, and coaxial cable is used for the signal. When more than one radiator is needed, they can be daisy-chained using the same type of cable. One LT-82 can power up to two

radiators.2
