OPERATION
Automatic Turn-On Selection: The DXA series offers two 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.
• 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 DXA 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.
Crossover Control: The variable crossover on the side of the amplifi er allows you to adjust the lo-pass
crossover frequency from 50–200Hz. The setting for this control is subjective; 80Hz is a good place to start.
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 side of the amplifi er is designed to give you
increased output, 0–12dB, at 40Hz. 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.
Remote Bass-CXRC (sold separately): With the optional 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 6
for installation.
