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 KXMA 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 KXM 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. Delay, reversing positive/negative polarity, or 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.
