Troubleshooting - Kicker KXA400.1 Benutzerhandbuch

Press the KXARC knob to cycle through GAIN, SHOC, PHASE, and CLIP settings, then rotate the knob
to adjust the corresponding values. The KXARC supports up to 4 KICKER KXA amplifi ers featuring a
subwoofer channel.
Gain: The KXARC gain control is a gain attenuator from -26dB to 0dB. This will allow you to conveniently
adjust the gain of the subwoofer channel on the fl y, with the maximum being the gain setting you've
selected on the KXA amplifi er side panel.
SHOCwave: The SHOCwave (Sub Harmonic Octave Creation) will restore low frequencies that are
weaker in older recordings or lost in data compression. The SUBWOOFER channel must be operating
with a full-range signal for this effect to work properly. Press the knob until SHOC is illuminated, then
adjust the knob to a level that is satisfactory.
Phase: The PHASE setting allows you to select the phasing of the subwoofer frequency; 0°, or 180°. If
you are experiencing an absence of bass in the audio, the bass frequency may be out of phase with the
rest of the system. Changing subwoofer location may also resolve these types of issues. The top LEDs
will indicate 0°, while the bottom will indicate 180°.
Clip: The CLIP indicator will illuminate the LED corresponding to an amplifi er with a clipped output signal
when CLIP is selected. Simply press the KXARC knob until CLIP is selected, then watch the bottom 4
LEDs to see which amplifi er is clipping and at what time. If CLIP is not selected, the CLIP LED will act as a
global clip indicator. If you change your Gain or SHOCwave setting, you may notice the CLIP LED become
active. This means your new DSP settings have caused an output to clip and you should reduce the gain
or compensate in some other way.

TROUBLESHOOTING

If your amplifi er does not appear to be working, check the obvious things fi rst such as blown fuses, poor
or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There is a
Protection (PRT) LED on the side panel of your Kicker KX series amplifi er. Depending on the state of the
amplifi er and the vehicle's charging system, the LED will either glow red or be off.
Red (PRT) LED fl ickering with loud music? The red (PRT) LED indicates low battery voltage. Check
all the connections in your vehicle's charging system. It may be necessary to replace or charge your
vehicle's battery or replace your vehicle's alternator.
Red (PRT) LED on, no output?

recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow
