This Class B digital apparatus complies with Canadian ICES-003. Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.

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.
