AMPLIFIER SETTINGS
Stereo / Mono Input Configuration
The STEREO / MONO switch allows the WCC-1600.2 amplifier to use a single RCA or high-
level input to feed signal to both the right and left channels of the amplifier. When the
switch is to the right (MONO position), signal from the left input is routed to the right chan-
nel. When the switch is to the left (STEREO position), right and left inputs are independent.
This allows a source unit with an internal balance to change the stereo imaging.
Input Gain
The WCC-1600.2 amplifier has separate front and rear level gain adjustments. The input
sensitivity of these adjustments range from 200mV up to 5V. This allows easy integration
from any source unit. Refer to the Testing the System and the Adjusting the Sound of the
System sections for detailed instructions on setting up the level controls.
Remote Gain Operation
The remote gain port provides easy remote access to the internal gain structure of the rear
channels of the WCC amplifier. The RGC-1* plugs into the amplifier via the 1/8" mini jack
plug. It can be installed in the front of the vehicle to control the amplifier gain level, and
can be used as a bass level control when used on an amplifier dedicated to subwoofers.
In addition, one RGC-1 can be used on multiple amplifiers. Plug the RGC-1 into the first amp.
The first amp must have its RCA output selection switch in the MASTER or GAIN position.
The RGC-1 information will now be sent to subsequent amps via the MASTER signal.
Auxiliary Output Configurations
The auxiliary outputs on this WCC amplifier offers easy, unlimited system expansion.
Routing signal from a source unit, pre-amplifier, or equalizer is a matter of connecting
RCA's to the RCA Inputs and the RCA outputs to the next WCC amplifier in the signal chain.
When the switch is in the COPY position, the RCA output is an identical copy of the input
signal. The signal passes through a buffer stage so that several amplifiers can be daisy
chained without signal loss or overloading of the source unit. This maximizes the signal out-
put and minimizes the potential for system noise.
When the switch is in the GAIN position, the 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 (RGC-1) can be connected to the amplifier and act as a PRE-AMP controlling
the overall level of the system. Following amplifiers are configured in the COPY mode 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 RCA outputs are buffered through the gain
stage of the amplifier and filtered through the crossover sections of the amplifier. When set
this way, the amplifier's gain and crossover settings are sent to other amplifiers down the sig-
nal chain. This can be useful for configuring multiple subwoofer amplifiers easily in a large
SPL system. All subsequent 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 control
all the functions of the slave amps via the MASTER RCA output signal.
* The RGC-1 is not supplied with the amplifier (order Orion part number 58000).
