System Overview

Multiple Channel System

A multiple channel system consists of two to four LT-82 transmitters and one or more radiators. The diagram

EHORZVKRZVVXFKDV\VWHPZLWKWZRUDGLDWRUV7KHUDGLDWRUVDUHSRZHUHGIURPWKHSRZHUVXSSO\IURPWKHÀUVW 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 issupplied 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.

	Up to 100 LA-140 radiators can be daisy chained
	together (using RG-58 cable) to provide sufficient
	Up to four LT-82 transmitters can	IR power for most applications
	be daisy chained together (using
	RG-58 cable) to create a	LA-140 IR Radiator
