OPERATION
Automatic Turn-On Selection:
The PXA series offers two automatic turn-on modes that can be selected on
the end panel; +12V or DC Offset. Using the DC Offset mode causes the REM terminal wire 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 the PXA harness. Run 18
gauge wire from the Remote Turn-On Lead on your source unit to the REM wire on the PXA harness. (Best
for Lo-Level input)
•
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. (Best for Hi-Level input)
Input Level:
The RCA inputs on KICKER PXA amplifi ers are capable of receiving either Hi or Low-level signals
from your source unit. When using a Hi-Level signal, simply set the Input Level switch on the amplifi er to HI.
Fader Switch:
Turn the fader switch ON 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.
HI-PASS Switches:
Use the HI-PASS switches behind the protective rubber covering of the amplifi er to set the
internal crossover. Choose a cutoff of 60Hz, 80Hz, 120Hz, or OFF depending on the confi guration of switches.
Never change the switches with the audio system on!
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.
