SUB WOOFER REAR-PANEL CONTROLS AND CONNECTION
-
Power 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 and will return to the Standby mode when no audio signal is detected after approximately 10 minutes. Setting this switch to ‘On’ keeps the subwoofer powered until Power Switch is turned ‘Off.’ -
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 blue, the subwoofer is turned On.
- When the LED glows red, the subwoofer is in the Standby mode.
-
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. -
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. -
Volume:
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. -
Subwoofer (LFE Input):
Connect the subwoofer to the dedicated subwoofer / LFE output of a receiver/processor. -
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. -
Power Input:
After you have made and verified the subwoofer’s input connection, 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
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 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 sub woofer
would be placed), and listen until you find the location where the bass
performance is best. Place the sub woofer in that location.

OPERATING THE SUBWOOFER
TURNING THE SUBWOOFER ON AND OFF
Set the subwoofer’s Power Switch to the ‘On’ position. Now set the subwoofer’s
Power Mode to the ‘Auto’ 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 blue 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
The Crossover control adjusts the subwoofer’s built-in low-pass filter
crossover between 50Hz and 150Hz. 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.
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 volume control to set the subwoofer’s volume. Turn the knob clockwise
to increase the subwoofer’s volume; turn the knob counterclock-wise 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 volume
control setting.
Notes on Setting Subwoofer Volume:
- Sometimes the ideal subwoofer volume setting for music is too loudfor 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 speakers. If the subwoofer were to play out
of phase with the speakers, the sound waves from the speakers 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 and the listener(s) 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 speakers, the sound will be clearer and have maximum impact, and percussive sounds like drums, piano and plucked strings will sound more life-like. 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.
USING THE SUPPLIED CARPET SPIKES
Four metal spikes are supplied for use when you place the subwoofer on a
carpeted surface. Do not use these spikes when placing subwoofer on non-
carpeted surfaces.
To insert the spikes:
- Gently lay the subwoofer on its side (not its front or back) on a soft, nonabrasive surface.
- Screw each spike into the threaded insert in each foot. Make sure all four spikes are screwed in completely for stability.
Note: NEVER drag the sub woofer to move it. Always carefully lift the sub woofer and carry it to its new location.
