OPERATION
Automatic Turn-On Selection:
The KX 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 6V 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.
Input Level:
The RCA inputs on KICKER KX 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.
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:
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.
KICK EQ Bass Boost Control:
The variable bass boost control on the side of the amplifi er 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
readjust the input gain control to avoid clipping the amplifi er.
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.
