SUBWOOFER REAR-PANEL CONTROLS AND CONNECTIONS
1) 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 speakers. This adjustment helps achieve a
smooth transition of bass frequencies between the subwoofer and the
speakers for a variety of different rooms and subwoofer locations.
2) 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.
3) Bass Boost: When switched to 'On,' this boosts bass level for added
low-end power.
4) Power On Mode: When switched to 'Auto' position, the subwoofer will
then be in 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 by its inputs after approximately 10 minutes. Otherwise,
subwoofer will always remain powered until Power Switch is turned 'Off.'
5) Subwoofer Level: Use this control to adjust the subwoofer’s volume. Turn
the knob clockwise to increase the volume; turn the knob counterclock-wise
to decrease the volume.
6) 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 the subwoofer is in the Standby mode.red,
7) 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.
• 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.
8) Power Switch: Set this switch in the ‘On’ position to turn the
subwoofer on.
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.
9) Power Cord: After you have made and verified the subwoofer’s input
connections, plug 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.

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 ( ) generally will maximize amount of bass in the 1
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.
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 sub-
woofer 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.

In many rooms, placing the subwoofer along the same plane as the left and right
speakers ( ) can produce the best integration between the sound of the subwoofer 2
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
