Running more than one of the same amplifier

(Master/Copy)

NOTE: When expanding your system by adding additional Orion

amplifiers in the signal chain use only the same model(s) as the first

amplifier in the chain. Refer to Adjusting the Sound of the System

(Advanced) under Setup and Troubleshooting section of the manual,

this will insure that all amplifiers on the chain are working at the same

potential.

The line outputs on Orion amplifiers offer easy, unlimited system

expansion. Routing signal from a source unit, pre-amplifier, or equal-

izer is a matter of connecting RCAs to the RCA inputs of the first Orion

amplifier and then the RCA line outputs to the next Orion amplifier’s

RCA line inputs in the signal chain. Then the LINE OUT switch on each

of the amplifiers is set as follows: The first amplifier in the signal chain

will have its LINE OUT switch set to the MASTER position. In effect

this first amplifier will set the Crossover, Intelli-Q and have remote

gain control for the remainder of the amplifiers in the signal chain.

The Crossover on all the Copy amplifiers should be set at the highest

frequency at 300Hz, and the Intelli-Q should be set at the lowest fre-

quency at 20Hz this will allow the Master to control the crossover and

Intelli-Q setting for all of the copy amplifiers. The remaining amplifiers

following in the signal chain will have their LINE OUT switch set to the

COPY position. This allows the signal to be input directly, bypassing

the subsequent amplifiers gain control. Refer to item #7 under Top

Panel Layout of End panel Layout section of this guide for LINE OUT

settings explanation.

The following is an example of how to wire multiple amplifiers using

one input from the source unit. This can be done with as many ampli-

fiers in the chain as necessary.
