INTRODUCTION
The RGC-1 remote gain control is specifically designed for use with ORION amplifiers. The
RGC-1 allows dashboard control to your current Orion amplifier or earlier XTR, XTR Pro or
HCCA amplifier. Used on subwoofer amplifiers, it provides subwoofer level control. Used on
the first amplifier in a daisy-chain, it works as a remote pre-amp volume control.
Warning: The RGC-1 can be used only on ORION amplifiers that have a
1/8-inch mini-jack remote gain port on the connection panel. Using the
RGC-1 with other ORION products will damage the system.
OPERATION
The RCG-1 is shipped in its retracted position. To adjust the control, press and release the
knob. The knob will extend for adjustment.
Clockwise rotation of the control knob increases the gain of the amplifier. Counterclockwise
rotation reduces the gain. See the “Adjustment” section for information on how to set the
various level controls in the system to get the proper range of operation for the RGC-1. The
control knob can be pushed in to its retracted position after adjustment.
WIRING
Connect the RGC-1 to the ORION amplifier connector with the attached 1/8-inch mini-plug cable.
If your system requires a longer cable, a standard head phone extension cable can be used.
The RGC-1 has optional night-time illumination provided by the GREEN and RED wires. For
Red color illumination, connect the RED wire to a +12 Vdc source and the GREEN wire to
chassis ground. For Green color illumination, connect the GREEN wire to a +12 Vdc source
and the RED wire to chassis ground.
INSTALLATION
Under Dash Mounting
To mount the RGC-1 under the dash or in an area that cannot be drilled through to accommodate the control, use the supplied under dash mounting bracket. Find a suitable location
which will not interfere with driving that is easy to reach. Mount the bracket in place using
the 2 screws and secure the RGC-1 to the bracket as shown below.
