On/Standby LED: When the Power-On Mode switch is in the “Auto”
position, this LED indicates whether the subwoofer is in the On or Standby
state:
• When the LED glows green, the subwoofer is turned on.
• When the LED glows red, the subwoofer is in the Standby mode.
When the Power switch is set to “Off,” the LED will not light up, no matter
what setting the Power-On Mode switch is in.
Crossover Control: This control determines the highest frequency at
which the subwoofer reproduces sounds. The higher you set the Crossover control, the higher in frequency the subwoofer will operate and the
more its bass will “overlap” that of the satellite speakers. This adjustment helps achieve a smooth transition of bass frequencies between the
subwoofer and the satellites for a variety of different rooms and subwoofer
locations.
NOTE: The Crossover control functions only when you are using the LineLevel In L/R connectors. The Line-Level In LFE connector bypasses the
subwoofer’s built-in crossover and Crossover control.
Phase Switch: This switch determines whether the subwoofer driver’s
piston-like action moves in and out in phase with the satellite speakers. If
the subwoofer were to play out of phase with the satellite speakers, the
sound waves from the satellites could partially cancel out the sound waves
from the subwoofer, reducing bass performance and sonic impact. This
phenomenon depends in part on the placement of all the speakers relative
to each other in the room.
Power-On Mode Switch: When this switch is set in the “Auto” position and the Power switch is set to “On,” the subwoofer will automatically
turn itself on when it receives an audio signal and will enter the Standby
mode when it has gone without receiving an audio signal for 20 minutes.
When this switch is set in the “On” position, the subwoofer will remain on
whether or not it is receiving an audio signal.
Subwoofer Level Control: Use this control to adjust the subwoofer’s
volume. Turn the knob clockwise to increase the volume; turn the knob
counterclockwise to decrease the volume.
Line-Level In LFE Connector: This input bypasses the subwoofer’s
internal crossover circuitry, so use it only with a receiver or processor subwoofer output that has been low-pass filtered. If your receiver or processor
does not have a dedicated subwoofer output that is low-pass filtered, use
the subwoofer’s Line-Level In L/R Connectors (see below) instead.
Use the supplied mono RCA cable (purple connectors) to connect the
Line-Level In LFE connector to the dedicated subwoofer output of a
receiver or preamp/processor.
Line-Level In L/R Connectors: These inputs pass through the subwoofer’s built-in crossover. Use them if your receiver or preamp/processor does
not have a dedicated subwoofer output that is low-pass filtered.
Power Switch: Set this switch in the “On” position to turn the subwoofer
on. The subwoofer will then be in On or Standby mode, depending on the
setting of the Power-On Mode switch.
Power Cord: After you have made and verified all subwoofer and speaker
connections described in this manual, plug the power cord into an active, unswitched electrical outlet for proper operation of the subwoofer.
DO NOT plug this cord into the accessory outlets found on some audio
components.

PlacIng the suBwooFer
The performance of a subwoofer is directly related to its placement in the listening room
and its physical position relative to the other speakers in the system.
While it is true that in general our ears do not hear directional sounds at the low
frequencies where subwoofers operate, when installing a subwoofer within the limited
confines of a room, the reflections, standing waves and absorptions generated within
the room will strongly influence the performance of any subwoofer system. As a result,
the specific location of the subwoofer in the room does become important to the
amount and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will increase the amount of
bass in the room; placing it in a corner (1) generally will maximize amount of bass in the
room. However, corner placement can also increase the destructive effect of standing
waves on bass performance. This effect can vary depending on the listening position
– some listening positions may yield very good results while others may have far too
much (or too little) bass at certain frequencies.

In many rooms, placing the subwoofer along the same plane as the left and right speakers (2) can produce the best integration between the sound of the subwoofer and that
of the left and right speakers. In some rooms, the best performance could even result
from placing the subwoofer behind the listening position (3).
We strongly recommend that you experiment with placement before choosing a final
location for your subwoofer. One way you can determine the best location for the subwoofer is by temporarily placing it in the listening position and playing music with strong
bass content. Move around to various locations in the room while the system is playing
(putting your ears where the subwoofer would be placed), and listen until you find the
location where the bass performance is best. Place the subwoofer in that location.

TURNING THE SUBWOOFER ON AND OFF
Set the subwoofer’s Power switch to the “On” position.
• If the subwoofer’s Power-On Mode switch is set to “Auto,” the
subwoofer will automatically turn itself on when it receives an audio
signal, and it will go into Standby mode after it has received no audio
signal for 20 minutes. The subwoofer’s LED will glow green when the
subwoofer is on and will glow red when the subwoofer is in Standby.
• If the Power-On Mode switch is set to “On,” the subwoofer will remain
on at all times. The subwoofer’s LED will glow green.
If you will not be using the subwoofer for an extended period – for
instance, if you’re going on vacation – set the Power switch to the “Off”
position.
SUBWOOFER ADJUSTMENTS: CROSSOVER
CONTROL
NOTE: The Crossover control functions only when
you are using the Line-Level In L/R connectors.
The Line-Level In LFE connector bypasses the
subwoofer’s built-in crossover and the Crossover
control.
The Crossover control adjusts the subwoofer’s
built-in crossover between 50Hz and 200Hz. The
higher you set the Crossover control, the higher in
frequency the subwoofer will operate and the more
its bass will “overlap” that of the satellite speakers.
This adjustment helps achieve a smooth transition of bass frequencies
between the subwoofer and the satellites for a variety of different rooms
and subwoofer locations.
To set the Crossover control, listen for the smoothness of the bass. If the
bass seems too strong at certain frequencies, try a lower Crossover control setting. If the bass seems too weak at certain
frequencies, try a higher Crossover control setting.
SUBWOOFER ADJUSTMENTS: VOLUME
Use the Subwoofer Level control to set the
subwoofer’s volume. Turn the knob clockwise to
increase the subwoofer’s volume; turn the knob
counterclockwise to decrease the volume. Once you
have balanced the subwoofer’s volume with that of
the other speakers in your system, you shouldn’t
have to change it.
SUBWOOFER ADJUSTMENTS: PHASE
The Phase switch determines whether the subwoofer driver’s pistonlike action moves in and out in phase with the satellite speakers. If the
subwoofer were to play out of phase with the satellite speakers, the sound
waves from the satellites could partially cancel out the waves from the subwoofer, reducing bass performance and
sonic impact. This phenomenon depends
in part on the placement of all the speakers relative to each other in the room.
Although in most cases you should leave
the Phase switch in the “Normal” position,
there is no absolutely correct setting for
the Phase switch. When the subwoofer
is properly in phase with the satellite speakers, the sound will be clearer
and have maximum impact, and percussive sounds like drums, piano and
plucked strings will sound more lifelike. The best way to set the Phase
switch is to listen to music that you know well and to set the switch in the
position that gives drums and other percussive sounds maximum impact.

tend to increase its bass output, while placing it away from any walls
