Running More Than One Of The Same Amplifier (Master/Copy) - Orion HCCA HCCA25001 Owner's Manual

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.
