Highlights
Listen Stationary IR System
There are three main components involved in the Listen Stationary IR system:
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.
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 ll 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
con gurations, comes standard with each radiator, and
the radiator is available in two colors; grey or white.
Receiver(s)
The IR light from the radiators is detected by
the receivers and turned into sound. Listen
o ers 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.

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.
