Phase switch: This switch determines whether the subwoofer transducer’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
cancel out some of the subwoofer’s sound waves, reducing bass performance and sonic
impact. This phenomenon depends in part on the placement of all the speakers in the
room. In most cases, the Phase switch should be left in the “Normal” position. However,
it does no harm to experiment, and you can leave the Phase switch in the position that
maximizes bass response and impact.
Bass Boost switch: Set this switch to “On” to enhance the subwoofer’s low-frequency
performance. Set this switch to “Off” for normal low-frequency performance.
Power On Mode switch: When this switch is set in the “Auto” position and when 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 after it has received no audio
signal for about 15 minutes. When this switch is set in the “On” position, the subwoofer
will remain on whether or not it is receiving an audio signal. An LED on the subwoofer’s
top panel indicates whether the subwoofer is in the on or standby state:
• When the LED glows white, the subwoofer is turned on.
• When the LED is not illuminated, the subwoofer is in the standby mode. When the
Power switch is set to “Off,” the LED will not be illuminated, no matter what setting
the Power On Mode switch is in.
Subwoofer Level control: Use this control to adjust the subwoofer’s volume. Turn
clockwise to increase the volume; turn counterclockwise to decrease the volume.
Input Mode switch: When this switch is in the “Normal” setting, the input signal from
the Line-Level L/R In connectors is active. When this switch is in the “LFE” setting, the
input signal from the Line-Level LFE In connector is active.
External Trigger Input connector: Use the supplied trigger cable to connect the External
Trigger Input connector to the trigger output of another compatible component. Whenever
the subwoofer detects a trigger signal between 3V and 30V (AC or DC), its amplier will
turn on. The amplier will turn off after the trigger signal ceases, even when the Power
On Mode switch is in the “Auto” position.
Line-Level LFE In connector: The signal from this connector bypasses the subwoofer’s
internal low-pass crossover. 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 Line-Level LFE In connector. You must also set the subwoofer’s Input Mode
switch in the “LFE” position.
Line-Level L/R In connectors: The signals from these connectors pass through the
subwoofer’s internal low-pass crossover. 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-Level L/R In connectors. You must also set
the Input Mode switch in the “Normal” position. If your receiver/processor has only one
subwoofer output, you can use either the L or R connector.
Wireless Code switch: This switch selects between four different channels for the
wireless subwoofer signal.
IMPORTANT: Be sure to set the subwoofer’s Wireless Code switch to the same channel
that you set the transmitter module’s Wireless Code switch. See Wireless Code Settings,
on page 10, for more information.
Power switch: Set this switch in the “On” position to turn the subwoofer on. The
subwoofer will then be either on or in the standby mode, depending on the setting of the
Power On Mode switch.
Power Cord (non-detachable): After you have made and veried all the connections
described in this manual, plug this cord into an active, unswitched electrical outlet for
proper operation of the subwoofer. DO NOT plug this cord into the accessory outlets
found in some audio components.
