iii. Bass Boost Control
This control allows you to increase bass response between 50 and 100Hz for certain types of audio that lacks in
bass, such as old recordings etc.
vi. Polarity Control
This control allows you to match the arrival times of the sound waves of the Sub8 Rox and the main speakers to
your listening area. While the system is playing, flip the switch to the 180º and back to 0º until the bass sounds
louder or less boomy. Depending on placement and room acoustics, this control may or may not have any affect.
v. Volume Limit Control
Use this control to adjust the maximum volume setting for your Sub8 Rox subwoofer. With the Volume Limit
control and front mounted volume control turned all the way down (counterclockwise), turn on the subwoofer
and start playing audio through your system. Turn the system up to the highest comfortable level – WITHOUT
DISTORTION. Now turn up the sub woofer volume on the front panel of the BBXW10 subwoofer amplifier all
the way. No bass should play. Next SLOWLY turn up the volume limit control until the subwoofer is playing at its
loudest level WITHOUT DISTORTION. Return levels to normal. Now anyone can safely turn up the subwoofer all
the way without damaging the system.
TROUBLESHOOTING
The Sub8 Rox Powered Subwoofer Rock System is designed to function trouble-free. Most problems occur because of operating
errors. If you have a problem, please check the troubleshooting list first. If the problem persists, contact Tech Support at 1-800-
448-0976 or e-mail us at [email protected].
A hum or buzzing sound is heard.
The sound may be caused by a ground loop in the system.
Try to eliminate this by reversing the AC plugs of other compo-
nents in the system.
Try plugging the amplifier into another outlet.
Other causes may include faulty cables.
The amplifier will not turn on.
The amplifier must be plugged into a live outlet. The power
switch on the rear panel must be on. A signal must be playing
into the input jacks, or speaker inputs.
The Protection Circuit cuts in momentarily and then
turns off.
The circuitry in the amplifier has detected that the amplifier or
subwoofer is in danger of overheating. Normally, this would
happen infrequently and momentarily. If it persists, the amplifier
may not be ventilated appropriately.
Move the amplifier to a better ventilated and/or cooler loca-
tion.
NOTE:
The amplifier may feel cool at the top, but still be
overheating. Do not use the temperature at the top of the
cabinet as a gauge for amplifier temperature.
The Protection Circuit cuts in and does not turn off.
There may be a fault in the wiring, the speaker, or the ampli-
fier. Turn the power switch off and then on again. If the ampli-
fier immediately returns to the Protection mode, turn it off and
check all of the wiring, including all connections at the amplifier,
at the subwoofer, and any connections made to the wall.
No sound is heard.
Audio cable to the amplifier is not connected properly or the
cable is bad. Use another cable that you know is good.
Check all speaker wire connections and plugs.
