OPERATION
audio inputs
Automatic Turn-On Selection: The CX series offers two different automatic turn-on modes; +12V and DC Offset.
•Remote Turn-On: Run 18 gauge wire from the Remote Turn-On Lead on your source unit to the terminal labeled REM between the amplifi er’s positive and negative power terminals. This is the preferred automatic turn-on method.
•DC Offset Turn-On: The DC Offset mode detects a 6V DC offset from the HI-Level speaker outputs when the source unit has been turned on.
Input Level: The RCA inputs on KICKER CX amplifi ers are capable of receiving either Hi or Low-level signals from your source unit. If the only output available from your source unit is a Hi-Level signal, simply press in the Input Level switch on the amplifi er. Refer to the wiring section of this manual for additional instructions.
Fader Switch: Depress the fader switch if you are running two sets of inputs (front and rear for example) to the amplifi er. Leave the fader switch OFF if you want to drive all channels from a single stereo input.
Sub Input: If there is no dedicated output on your source unit for a subwoofer, use the SUB INPUT switch to set your subwoofer input to either SUB INPUT or AMP INPUT 2.
Input Gain Control: The input gain control is not a volume control. It matches the output of the source unit to the input level of the amplifi er. Turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to 25). Next, slowly turn (clockwise) the gain on the amplifi er up until you can hear audible distortion, then turn it down a little.
Bass Boost Control: The variable bass boost control on the top of the amplifi er is designed to give you increased output, 0–12dB, at 40 Hz. The setting for this control is subjective. If you turn it up, you must readjust the input gain control to avoid clipping the amplifi er.
Crossover Control: The variable crossovers on the side panel of the amplifi er allow you to adjust the crossover frequency from 10–200Hz (AMPS 1 & 2) and 50–200Hz (SUB). The setting for this control is subjective; 80Hz is a good place to start.
Remote Bass-CXRC (not included): With the CXRC remote bass level control, you have the ability to control the output level of the amplifi er remotely. To surface-mount the CXRC remote bass level control, simply screw the remote to the chosen location, then run the cable from the controller to the “Remote Bass” jack on the amplifi er panel. Do NOT connect/disconnect while the amplifi er is on. Connecting the 3.5mm cable without the remote will cause the amplifi er to output at full gain, possibly damaging your speakers. See page 5.
