Automatic Turn-On Selection: The KX 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 KX 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. Either input method will provide a low-level output signal at the RCA output,
which effectively passes the audio signal to another amplifi er or component. Refer to the wiring section of this
manual for additional instructions.
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.
Crossover Switches with Frequency Multiplier: Use the XOVER switches on the end panel of the amplifi er
to set the internal crossovers of AMPS 1 & 2 to OFF, HI-PASS, LO-PASS, or BAND-PASS (AMP 2 only). When
the switch is set to OFF, a full bandwidth signal will be amplifi ed. Set the switch to HP if you want the amplifi er's
internal crossover to serve as a high-pass fi lter. Set the switch to LP if you want the amplifi er's internal crossover
to serve as a low-pass fi lter. Set the switch to BP when a specifi c frequency range is required. Never change the
crossover switches with the audio system on!
Set the 1X/10X frequency multiplier switch to the setting that is appropriate for your application. A setting of
10X will set the range of the AMP 1 crossover to 100–5,000Hz, and the LO-PASS crossover of AMP 2 to
400–5,000Hz.
KICK EQ Bass Boost Control: The variable bass boost control on the side of the KXM400.4 amplifi er is
designed to give you increased output, 0–18dB, 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.
