System Overview
A multiple channel system consists of two to four LT-82 transmitters and one or more radiators. The diagram
below shows such a system with two radiators. The radiators are powered from the power supply from the
rst transmitter. This power supply can supply enough power for the LT-82 and two LA-140 radiators. If you
need more than two radiators, you can use the power from the other transmitters. In this example, the four
transmitter power supplies can supply enough power for up to eight LA-140 radiators. This is discussed later
in this document. Power is supplied from standard CAT-5 cable while RF from the transmitter is delivered
using 50-ohm RG-58 coaxial cable. Each radiator is supplied with 25 feet (7.6 meters) of CAT-5 and RG-58
coaxial cable.
Multiple Channel System
Up to four LT-82 transmitters can
be daisy chained together
(using RG-58 cable) to create
a multi-channel system

Up to 100 LA-140 radiators can be daisy chained
together (using RG-58 cable) to provide
sufficient IR power for most applications

Radiator Power: Radiators can be
powered from the LT-82 (up to two
radiators) or an additional power supply
(LA-205) can power up to two radiators
Radiator RF: RF from the last LT-82 must be
daisy chained from radiator to radiator
