Phase Switch: This switch determines whether the subwoofer
transducer's piston-like action moves in and out in phase with the main
speakers. If the subwoofer were to play out of phase with the main
speakers, the sound waves from the main speakers 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 the listening position and to each other in the
room.
Input Mode Switch: When this switch is in the “Normal” setting,
the input signal from both Line In connectors is routed through the
subwoofer's built-in low-pass crossover network. When the switch is in the
“LFE” setting, the input signal from the LFE Input connector bypasses the
subwoofer's built-in crossover network.
Volume 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.
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 the Input Mode switch
is in the “Normal” setting.
On/Standby LED: When the Power switch is in the “On” 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.
Line In/LFE Input Connectors:
• When you’re connecting the subwoofer to the dedicated subwoofer
output of a receiver/processor that has its own low-pass crossover
network, use the LFE Input connector and set the Input Mode switch in
the “LFE” position.
• When you're connecting the subwoofer to the preamp or subwoofer
outputs of a receiver/processor that does not have its own low-pass
crossover network, use both Line In connectors and set the Input Mode
switch in the “Normal” position. If your receiver/processor only has one
subwoofer output you can use either Line In connector.
Power Switch: Set this switch in the “On” position to turn the subwoofer
on. The subwoofer will then be in the Standby mode. It will automatically
turn On when an audio signal is detected at its inputs, and will return
to the Standby mode when no audio signal is detected its inputs after
approximately 10 minutes.
If you will be away from home, or will not be using the subwoofer for an
extended period, set this switch in the “Off” position to conserve energy.
Power Cord Connector: After you have made and verified the
subwoofer’s input connections, plug the female end of the supplied IEC
power cord into the subwoofer’s Power Cord connector, and plug the
other end of the power cord into an active, unswitched electrical outlet for
proper operation of the subwoofer. DO NOT plug the power cord into the
accessory outlets found on some audio components.

ENGLISH
PLACING THE SUBWOOFER
CONNECTING 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. 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 approximately
10 minutes. The subwoofer’s LED will glow green when the subwoofer is
on and will glow red when the subwoofer is in Standby.
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 the Input Mode switch is in the “Normal”
position.
The Crossover control adjusts the subwoofer’s
built-in low-pass filter 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 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 the Level control
setting.
Notes on Setting Subwoofer Volume:
• Sometimes the ideal subwoofer volume setting for music is too loud
for films, while the ideal setting for films is too quiet for music. When
setting the subwoofer volume, listen to both music and films with
strong bass content and find a “middle ground” volume level that
works for both.
• If your subwoofer always seems too loud or too quiet, you may want
to place it in a different location. Placing the subwoofer in a corner will
tend to increase its bass output, while placing it away from any walls
or corners will tend to lessen its bass output.
SUBWOOFER ADJUSTMENTS: PHASE
The Phase 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
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.
