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 Line-Level 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.
