Automatic Turn-On Selection: The DX series offers three different automatic turn-on modes that can be
selected on the end panel; +12V, DC Offset, and Audio. Using either the DC Offset or Audio mode causes the
REM terminal to have +12V out for turning on additional amplifi ers.
• Remote Turn-On: Set the switch to +12V to use the remote turn-on lead from your source unit. 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: If Remote Turn-On is not an option, the next best setting is DC Offset. The DC Offset
mode detects a 6V DC offset from the HI-Level speaker outputs when the source unit has been turned on.
• Signal Sense Turn-On: The Audio setting is the fi nal alternative for Automatic turn-on. This is a Signal Sense
turn-on method that detects the incoming audio signal from your source unit and automatically turns on the
amp. This turn-on method will not work properly if the input gain control is not set appropriately.
Input Level: The RCA inputs on KICKER DX 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, and the hi-pass crossover from 10-30Hz (DX250.1 is fi xed at 80Hz and
25Hz). The settings for these controls are subjective; 80Hz is a good place to start for the lo-pass crossover,
20Hz for the hi-pass.
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 (For the DX250.1, use the Bass Boost switch to toggle between 0 or +9dB).
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-ZXRC (Not included with the DX250.1): With the ZXRC remote bass level control, you have the
ability to control the output level of the amplifi er remotely. To mount the ZXRC remote bass level control, simply
screw the metal bracket to the chosen location, then slide the housing onto the bracket until it snaps into place.
Run the cable from the controller to the “Remote Bass” jack on the amplifi er chassis. See page 5.
