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 amplifier 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, with gain knobs all the way down, slowly turn
(clockwise) the gain up until you see the LIMITER LED
light up or hear audible distortion, then turn it down
a little. If the LIMITER's LED comes on, the input is
still clipping. This step should be performed after
KEY Auto Setup and crossover settings have been
applied.
MIC INPUT: Connect the included microphone
to the 3.5mm (1/8") microphone input and use
in conjunction with the Auto Setup process to
automatically set Time Alignment, KICKER EQ, and
Output Level Matching. Install face up to headrest,
pointing as straight as possible to the roof.
TIME DELAY: Set to enable (EN) for all speaker's
output to reach the driver or microphone location at
the same time. Set to defeat (DF) to turn time delay
off.
KICKER EQ: Set to enable (EN) to turn KICKER EQ
on (recommended), set to defeat (DF) to turn KICKER
EQ off. When OFF, the frequency response curve will
be flat.
