AMPLIFIER SETTINGS

Signal Input and Output Configurations

The input section of the amplifier consists of a phase switch that sets the output configura-

tion, gain controls, and RCA inputs. The input section makes it easy to adapt this amplifier

to most system configurations.

Input Gain

The Orion HCCA D600 amplifier has a level adjustment to allow for easy integration with

any source unit. The input sensitivity can be adjusted from 150mV to 5V. Refer to Testing

the System and Adjusting the Sound of the System sections of this guide for detailed

instructions on setting the gain.

Phase Switches

0° - leaves output unaffected. The output signal is in phase with the input signal.

●

180° - inverts the output. The channel is 180° output of phase. This configuration

●

is useful for inverting the phase of subwoofers to improve staging in a vehicle.

This is also used when bridging two amplifiers into one speaker.

Line Output Configurations (System Expansion)

NOTE:

When expanding your system by adding additional Orion amplifiers in the signal

chain use only the same model(s) as the first amplier in the chain.

The line outputs on Orion amplifiers offer easy, unlimited system expansion. Routing signal

from a source unit, pre-amplifier, or equalizer 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 amplifi-

er's RCA line inputs in the signal chain. Then the Master/Slave switch on each of the amplif-

ers is set as follows:

The first amplifier in the signal chain will have its Master/Slave switch set to the MASTER

position. In effect this first amplifier will set the gain for the remainder of the amplifiers in

the signal chain.

The remaining amplifiers following in the signal chain will have their Master/Slave switch

set to the SLAVE position. This allows the signal to be input directly, bypassing the subse-

quent amplifiers gain control. The audio level is set and supplied by the output of the mas-

ter amplifier at its gain setting.

Internal Crossover Configurations

The crossover section of the Orion HCCA D600 amplifier is continuously variable and

extremely flexible.

When using Orion loudspeakers, minor deviations from the recommended frequency

ranges can provide superior results depending on your speaker locations and your vehicle

acoustics. Setting crossover frequencies higher than recommended will not cause damage

and may provide superior sonic results depending on your system's performance goals.

Refer to your loudspeaker owner's manual for assistance in choosing the proper crossover

frequencies for your system.

WARNING!

DO NOT set crossover frequencies lower than the speakers recommended
