KX Amplifiers
Operation
Navigation
On your Kicker amplifier there are three rotary controls on top
and one switch on the end panel. These controls ensure the
reliability and performance of the amplifier, so they need to be
set correctly.
SUBSONIC FILTER SWITCH
NEVER CHANGE THE SUBSONIC
FILTER SWITCH SETTING
WITH THE SYSTEM ON!
The switch located on the end panel next to the RCA jacks is
for the subsonic filter. It is 12db/octave set at 25 Hz. All KX.1
amplifiers come with a full-time variable low pass crossover
selectable from 50 Hz - 200 Hz.
BEFORE TURNING ON THE SYSTEM FOR THE FIRST TIME,
MAKE SURE THAT THE THREE ROTARY CONTROLS ON
TOP OF THE AMPLIFIER ARE TURNED FULLY COUNTER-
CLOCKWISE!
GAIN CONTROL
Remember, the gain control is not a volume control, it matches
the output of the head unit to the input level of the amplifier and
must be adjusted properly for best performance. All the way up
or down is not necessarily the best.Turn the head unit up to
about 3/4 volume. (eg. If the head unit goes to 30, turn it to 25.)
Next, turn (clockwise) the gain on the amplifier up slowly until
you can hear audible distortion, then turn it down just a little.
CROSSOVER CONTROL
Where you set the crossover is very subjective and can be fine
tuned to match your listening preference or speaker
requirements.
BASS BOOST
The BASS BOOST control is designed to give you increased
output at 40 Hz. The setting for this control is subjective,
however, if you turn it up, you must go back and adjust the gain
control to avoid clipping the amplifier.
