Kicker KMA.1 Série Manuel D'utilisation page 5

OPERATION
Automatic Turn-On Selection: The KMA series offers two different 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. This is the
preferred automatic turn-on method.
• 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 KMA 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, 0–6dB, 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-KMBLC: With the KMBLC remote bass level control, you have the ability to control the
output level of the amplifi er remotely. To surface-mount the KMBLC 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. See page 6 for installation.
