Operation Manual
DC Control (12v Trigger)
The DC Control input lets you power on/o the subwoofer
and other home theater equipment (ex. amplifier or receiver)
at the same time, while also providing a faster way to power on
the subwoofer than normal signal detection. To get the most
from the DC Control’s functionality, connect the DC input (12V)
on your subwoofer to the DC output (12V) on your receiver
or amplifier using a 1/8” TS cable. Be sure to switch your
subwoofer to DC Control/12V Trigger mode. When the
subwoofer receives the 12V input it will immediately turn on,
and stay on, until it stops receiving a 12V signal. If you want to
use the signal detect function, simply restart the subwoofer by
switching the power switch to “O,” wait 10 seconds, and then
flip it back to “Auto On.”
Troubleshooting
When connecting your cables, always make sure the
subwoofer is turned o to prevent any/all damage.
No sound is coming from subwoofer or the subwoofer
doesn’t sound right
If connection is set from your receiver’s ‘sub out’ to the
subwoofer LFE, check the receiver is configured to enable the
subwoofer (see receiver owner’s manual for more information).
Subwoofer has no power
Check outlet; check fuse after unplugging the subwoofer.
Powering Your Subwoofer
Your system includes a detachable power cord that’s
packaged separately from the cabinet. Insert female end
into the receptacle on the amplifier plate and insert the
polarized AC plug into a wall outlet (or power strip).
We do not recommend connecting the subwoofer’s
AC power cord to your receiver’s switched outlet.
Adjusting Your System
Subwoofer Adjustments
Your powered subwoofer oers a range of setting options.
We recommend the following settings as starting points,
but the settings that are best for you depend on your
speaker placement, electronics and personal taste. After
you’ve become familiar with what the settings do, experiment
with alternate options to find the method that works best
for your system setup.
AC Power Connection and Auto On/O
Your subwoofer features circuitry which automatically
turns your subwoofer on when it senses an audio signal.
When no signal is present, the subwoofer goes into standby
after 20 minutes.
Fine Tuning your Subwoofer
• Volume—When you set up your subwoofer for the first
time, you may have to make adjustments several times
before you hear what you personally like. Start with the
volume at 50%. Adjust by ear using a wide variety of
CDs and video sources. Adjust for deep, powerful bass
without “boominess.”
• Low Pass—NOTE: This control does not work when
the subwoofer is connected with the LFE Input.
This control adjusts the frequency range over which the
subwoofer operates. When using smaller main speakers,
the upper range of the control will probably yield the best
results. With larger speakers, the lower end of the control
range will probably sound best, but always let your ear be
the final judge. If male vocals sound “thin,” turn this control
up until the voice sounds rich but not “boomy.” If male
vocals sound too “thick” or “chesty,” turn this control
down until the voice sounds natural.
• Phase Switch—Sit in your favorite listening position.
Play music (not a movie) with a walking bass line. We
recommend playing jazz or country music. Now listen
carefully for the point at which the subwoofer transitions
to your main speakers. This is the crossover point, and this
point should be below the frequency of a male human
voice. Whichever phase setting sounds louder or fuller at
the subwoofer’s crossover (transition) point is the optimum
setting. Sometimes no dierence will be heard.
