Orion Car Audio HCCA50001, HCCA25001 Running more than one of the same amplifier Master/Copy

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.
