Adjustable Subsonic Filter: The variable subsonic fi lter will provide a cut-off point for lower frequencies
(10–80Hz) that could potentially damage your speakers from over-excursion, along with wasting your
amplifi er's power. The setting for this control should be set relative to your speaker's low-frequency
capability. The setting for this control should be set relative to your speaker's low-frequency capability, and
is recommended for ported enclosures.
KickEQ Bass Boost Control: The variable bass boost control on the side of the amplifi er is designed
to give you increased output, 0–6dB, at the selected frequency. 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.
Remote Bass-KMBLC: With the KMBLC remote bass level control, you have the ability to control the
output level of the amplifi er remotely. To surface-mount the KMBLC remote bass level control, simply
screw the remote to the chosen location, then run the cable from the controller to the "Remote Bass" jack
on the amplifi er panel. Do NOT connect/disconnect while the amplifi er is on. See page 8 for installation.
GAIN MATCHING
In any audio system, the goal is to reach maximum input and output levels without distortion or clipping.
The engineers at KICKER have taken the guesswork, and hassle, out of matching the output voltage of
your source unit to the amplifi er with the Gain Matching feature. To begin, you'll need to download the
KICKER test tones from www.kicker.com/test-tones. The following fi les are available in MP3 and WAV
formats:
1kHz @ 0dBFS, 50Hz @ 0dBFS, 1kHz @ -10dBFS, 50Hz @ -10dBFS, 1kHz @ -5dBFS, 50Hz @ -5dBFS
These test tones are sine waves meant to provide a consistent signal for the KXMA amplifi er to reference.
The different recording levels are designed to give you the perfect gain match for your application.
0dBFS: Designed for audiophile applications to give you distortion free audio output with the most
dynamic range.
-5dBFS: Designed for normal/daily applications, there will be less dynamic range but higher potential
audio output levels. With this set up you can get some occasional clipping from the amplifi er.
-10dBFS: Designed only for Subwoofer applications, there will be less dynamic range but higher potential
audio output levels. With this set up you can get some clipping from the amplifi er.
Afterwards, use the following procedure to accurately Gain Match your amplifi er(s):
1. Disconnect the speakers from the KXMA amplifi er.
2. Set all EQ and crossover settings to fl at on your source unit.
3. Play the downloadable fi le from KICKER.com
4. Turn the source unit up to 3/4 volume.
5. Increase the gain of the amplifi er until the Gain LED turns on.
6. Decrease the gain of the amplifi er until the Gain LED turns off.
