Setting 4 inverts the output of both the left and right channels. Both left and right gain
controls are active. This configuration is useful for inverting one set of speakers like rear
speakers in front/rear system to improve staging in a vehicle (page 25).

Setting 5 inverts the output of the left channel. The left channel is 180® out of phase
from the right channel. Only the right gain control is active. This is the "MONO
BRIDGED" output configuration (page 29). This setting is to be used when using a single
RCA as a mono Input. Right Phase control determines the phase of the output. When
the Right Phase control is in the 0" position, the bridged output is in phase with the rest
of the system.
Setting 6 inverts the output of the bridged output. The mono bridged input is 180® out
of phase from the rest of the system. Only the right gain control is active. This is the
"MONO BRIDGED" output configuration (page 29). Right Phase control determines the
phase of the output. When the Right Phase control is in the 180® position, the bridged
output is out of phase with the rest of the system.

HCCA amplifiers have separate left and right level adjustments. The input sensitivity of
these adjustments range from 200mV up to 5Vrms to easily integrate with any source
unit both after market and OEM (Original Equipment Manufacturer) Refer to the "Test¬
ing the System" (page 38) and the "Adjusting the Sound of the System" (page 39) for
detailed instructions on setting the gain.

AUXIUARY OUTPUT CON FIG U RATION
The auxiliary outputs on ORION amplifiers offer easy, unlimited system expansion.
Routing signal from a source unit, pre-amplifier or equalizer is a matter of routing
RCAs to the RCA Inputs and out the AUX outputs to the next XTREME or HCCA
amplifier in the signal chain. When the switch is in the "COPY" position, the AUX
RCAs output is an identical copy of the input signal. The signal passes through a
buffer stage so that an infinite number of HCCA amplifiers can be daisy chained
without signal loss or overloading of the source unit. This maximizes the signal
output and minimizes the potential for system noise.
When the switch is in the "GAIN" position, the AUX RCA outputs are buffered
through the gain stage of the amplifier. When the first amplifier in the signal chain
is set this way, a remote gain controller can be installed in the amplifier and act as
a "PRE-AMP" controlling the overall level of the system. Following amplifiers can
be configured in either the "COPY" configuration with their gains set to zero as
the "GAIN" amp is now controlling the gain level for all subsequent amps. This
eliminates the need to "gain match" multiple amplifiers.
When the switch is in the "MASTER" position, the AUX RCA outputs are buffered
through the gain stage of the amplifier and filtered through the crossover sec¬
tions of the amplifier. When set this way, the amplifier's gain and crossover set¬
tings are sent to other amplifiers down the signal chain. This can be useful for
configuring multiple subwoofer amplifiers easily in a large SPL system. All subse¬
quent amplifiers after the master amp will be in the "COPY" position and have
their gains set to zero and all crossovers turned off. The master amplifier will con¬
trol all the functions of the slave amps via the "MASTER" AUX OUT signal. In ad¬
dition, one RGC-1 gain module can be used to control the level of an entire sub
system by plugging it into the "MASTER" amp
