Automatic Turn-On Selection: The KXMA 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.
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 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.
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.
