Operation
1.
Automatic
Turn-On Selection The LX 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 amplifiers.
ORemote
Turn-On Set the switch to
+12Vto
use the remote turn-on lead from your source unit. Run
18 Ga wire from the Remote Turn-On Lead on your source unit
to
the terminal labeled
REM
between the
amplifier's positive and negative power terminals. This is the preferred automatic turn-on method.
ODC
Offset
Turn-On
If
Remote Turn-On
is
not an option, the next best setting
is
DC Offset. The DC
Offset mode detects a 6 volt surge from the
HI
Level speaker outputs when the source unit has been
turned on.
OSignal
Sense Turn-On The
Audio
setting
is
the final 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.
2.
Input
Level The RCA inputs on Kicker LX amplifiers 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 amplifier. Refer
to
the wiring section of this manual for additional
instructions.

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 amplifier. 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 amplifier up until you can hear
audible distortion, then turn it down a little.
4.
Bass
Boost
Control
The variable bass boost control on the
top
of the amplifier
is
designed
to
give
you increased output 0 - 18dB at 40
Hz.
The setting for this control is subjective.
If
you turn it up, you
must
go
back and adjust the input gain control
to
avoid clipping the amplifier.
5.
Crossover
Control
The variable crossover on the
top
of the amplifier allows you to adjust the
crossover frequency from 50-200Hz. The setting for this control
is
subjective; 80Hz
is
a
good
place
to
start.
6.
RemoteBass(Level Control) With the
remote bass level control, you have the ability
to
control the output level
of
the amplifier
remotely.
To
mount the remote bass level
control, simply screw the metal bracket
to
the chosen location. Then slide the housing
onto the bracket until it snaps into place.
Run
the cable from the controller
to
the "Remote
Bass" jack on the amplifier chassis.
TroubleShooting
4 Conductor
Phone Cable
If
your amplifier does not appear
to
be working, check the obvious things first such as blown fuses,
poor or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There
is
an
illuminated red badge on
top
of
the amplifier denoting the
power
state of the amp
in
addition
to
the Protection
LED
on the end panel
of
your Kicker
LX
series amplifier. When the red badge
is
lit this
indicates the amplifier is turned on and the amplifier
is
functioning properly.

With a Volt Ohm Meter
(VOM)
check the following:
1)
+12 volt
power terminal (should read
+12V
to
+16V)
2)
Remote turn-on terminal (should read +12V
to
+16V)
3)
Check for reversed power and ground connections.
4)
Ground terminal, for proper conductivity.
5)
Check for blown fuses.
