Automatic Turn-On Selection: The KXM 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 3V 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.
Radio Detect: The RCA inputs on KICKER KXM amplifi ers are capable of receiving either Hi or Low-level
signals from your source unit. If you are using Hi-Level inputs, but your source unit cannot detect an audio
system present or refuses to play audio out of one or more speakers, you may need to set Radio Detect
to ON. This will activate a load resistor at the amplifi er's inputs and tell the source unit there are speakers
present. Do NOT use Radio Detect if you are using a Low-Level input signal; doing so will greatly reduce the
input signal.
Input Gain Control with Gain Matching: 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 and features Gain Matching to prevent clipping the
input. For a quick setup, turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to
25). KICKER recommends using the test tones at www.kicker.com/support/ to reach the most accurate and
best performing settings. Next, slowly turn (clockwise) the gain on the amplifi er up until you see the Gain LED
light up or hear audible distortion, then turn it down a little. If the GAIN knob's backlight comes on, the input
is still clipping. For full instructions on Gain Matching, please see the next page.
Adjustable Subsonic Filter: The variable subsonic fi lter will provide a cut-off point for lower frequencies
(10–80Hz) that could potentially damage your speakers from over-excursion, along with wasting your
amplifi er's power. The setting for this control should be set relative to your speaker's low-frequency
capability. The setting for this control should be set relative to your speaker's low-frequency capability, and is
recommended for ported enclosures.
Crossover Control: The variable crossover on the amplifi er is always active, and allows you to adjust the
LO-PASS crossover frequency from 40–160Hz. The setting for this control is subjective; 80Hz is a good
place to start.
