Volume
This knob adjusts the subwoofer’s volume. Turn it clockwise for full volume. Note that the subwoofer level control in an AV
receiver will also affect how loud the subwoofer plays. With most AV receivers, setting this knob at about halfway up (the 12
o’clock position) will provide a volume level that allows the subwoofer’s level to be matched with that of the main speakers.
Phase
Use this knob to adjust the phase of the subwoofer relative to the main speakers. This will help achieve a smoother blend
of the sound of the subwoofer and the main speakers. To adjust it, sit in the chair or couch where you usually listen, and
play some bass-heavy music with the phase knob set to 0. Now play the same music with the knob set to 180. If you hear a
difference, experiment with different settings until the bass sounds smoothest from your chair.
Crossover
Use this knob to set the highest bass frequency the subwoofer will play, from 50 to 150 Hz. If you’re using an AV receiver or
surround-sound processor, set this knob at 150 and use the crossover built into the receiver or processor. If the subwoofer
is installed in a stereo system, set this knob as close as possible to the lowest rated bass extension of the main left and right
speakers.

Controls and Connections
Status Light
This light glows when the subwoofer’s power is on.
Off/Auto/On Switch
This switch functions only when the power switch
(see pg. 8 “Power Switch”) is set to “on.” When
this switch and the power switch are both set to
“on,” the subwoofer’s power will always be on.
When this switch is set to “auto,” the subwoofer’s
power will come on automatically when it senses
an incoming audio signal. If there is no signal for
15-18 minutes, the subwoofer will automatically
shut off.
8
Inputs
These jacks accept a signal from an AV receiver, a surround-sound processor, a stereo receiver or a stereo preamp. In
a surround-sound system, use an RCA audio interconnect cable (not included) to connect the receiver or processor’s
subwoofer output to the input jack labeled LFE. In a stereo system, connect two RCA cables (not included) from the
preamp or the receiver’s preamp output to the jacks labeled R and L.
USB 5VDC output
This jack outputs 5-volt DC power, which can be used to power accessories such as a wireless subwoofer receiver/
transmitter system.
Power switch
This is the master power switch that turns on the AC power. It must be in the “on” position for the subwoofer to
function. If the power switch is on, the on/auto/off switch (see pg. 7 “off/Auto/On Switch”) controls the subwoofer’s
power.
AC cord input
This connector accepts a standard two-conductor AC power cord (included). Note that the jack is not polarized, which
means the connector can be reversed. Reversing the AC cord in this jack can sometimes x hum (grounding) problems in
the audio system.
Subwoofer Placement
The more walls the subwoofer is near, the louder (and sometimes boomier) the bass will sound. If you want maximum
bass output, put the subwoofer in a corner. If this makes the bass too loud or boomy, move the subwoofer out of the
corner and closer to the center of the wall. Often, placing the subwoofer near or between the main speakers helps the
subwoofer blend better with the speakers, and gives the best compromise between maximum output and smoothest
sound. When you listen to evaluate different subwoofer positions, always do it from the chair or couch where most of the
listening will take place.
A simple trick used by many home theater enthusiasts is to place the subwoofer in the primary listening chair, play some
music with a melodic bass line (most pop and jazz recordings will work), and crawl around with your head about a foot or
two off the ground. Find the spot along the wall where the bass sounds the smoothest and most even from note to note,
and put the subwoofer there.

Subwoofer Adjustment
If the subwoofer is installed in a surround-sound system: Use the crossover frequency and level controls in the receiver or
surround processor, following the manufacturer’s instructions.
If the subwoofer is installed in a stereo system without a built-in subwoofer crossover: Set the subwoofer’s crossover
control to match the rated bass extension of the speakers as closely as possible—e.g., if you’re using tower speakers
with 40 Hz rated deep bass response, set the crossover control to 50 Hz.
If you’re not sure what the speakers’ bass rating is, start with this control set in the middle (about 100 Hz), with the
volume control set in the middle. Adjust the volume control until the bass level roughly matches the level of the main
speakers. If some bass notes seem to be too quiet, set the crossover control to a higher frequency. If some bass notes
seem too loud, set the crossover control to a lower frequency. Do all of your listening tests from the chair or couch where
most of the listening will take place.

Troubleshooting
Main speakers work but no sound from the subwoofer: If the status LED is not lit, make sure the subwoofer’s master
power switch and off/auto/on switches are set to “on.” If the status LED still does not come on, check to make sure
the AC cord is plugged into the subwoofer and the AC outlet. If the subwoofer is plugged into a power strip or power
conditioner, make sure that device is turned on and plugged into the AC outlet. If the status LED is lit but there’s still
no output from the subwoofer, check to make sure the RCA cables are connected from the receiver, surround processor
or preamp to the subwoofer, and that the cables are in good condition. If the cable connection is good, make sure the
subwoofer’s volume control is turned up. If there’s still no output, and you’re using a receiver or surround processor, make
sure the subwoofer level in the receiver or processor is turned up, and make sure the receiver or processor is congured
for a subwoofer (typically this will be a 5.1, 7.1, 5.1.2 or 7.1.2 conguration in the receiver or processor’s onscreen setup
menu).
Bass has too much boom: Turn the volume control on the subwoofer down slightly, move the subwoofer further from
the corner and closer to the middle of the wall, or if you have a stereo system, set the subwoofer’s crossover control to a
lower frequency.
Bass is too quiet or some bass notes are missing: Turn the volume control on the subwoofer up slightly, move the
subwoofer closer to one of the corners of the room, or if you have a stereo system, set the subwoofer’s crossover control
to a higher frequency.
Subwoofer makes humming sound all the time: Try unplugging the AC cord from the subwoofer, ipping it over, and
plugging it back in. If this doesn’t work, try connecting the subwoofer to the same AC outlet or power strip as the rest of
the audio system. Using a wireless transmitter/receiver can sometimes eliminate persistent hum problems.
