SUBWOOFER UNIT
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 and Transmitter Unit is
active with the internal low-pass crossover enabled. When this switch is in the “LFE” setting, the input signal from the Line-Level LFE In connector
and Transmitter Unit is active with the internal low-pass crossover bypassed.
External Trigger Input connector: Use the mini plug of the supplied combination LFE and 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 amplifier will turn on. The amplifier 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: 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
to bypass the subwoofer’s internal low-pass crossover.
