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.
