POWER SWITCH/AUTO/ON
The POWER ON switch near the bottom
of the panel supplies power to the sub
amplifier. When the AUTO/ON switch is
in the AUTO position, the subwoofer will
automatically turn on when it senses a signal.
The subwoofer will automatically go into

standby mode after 15 minutes with no signal.
When this switch is in the ON position, the
SUBWOOFER
subwoofer will remain on.
VOLUME CONTROL
This control affects the output of your
subwoofer, and should be set at lowest

This control affects the upper
100W/200W Dynamic Power
frequency limit of the subwoofer.
The control range is 40-180 Hz,
along with a disable (LFE) setting.
The slope of the low pass filter
is 12 dB/octave. For connection
to an A/V receiver, the low pass
should be set to LFE. For 2-channel applications, it should be adjusted to
blend with the bottom roll-off frequency of your loudspeakers.
PHASE CONTROL
This control delays the signal being processed through the amplifier. For
connection to an A/V receiver, it should be set to 0
degrees. For 2-channel systems, it should be adjusted
to obtain optimal transition between the loudspeakers
and the subwoofer, and best sound stage
ROOM POSITION
The placement of your subwoofer can add a significant difference to the
performance of your home theater system. Low frequencies are omni di-
POWER
rectional, but best performance results if you place the subwoofer in the
corner, as this will increase the level of bass output. You can experiment
with different configurations, or even add multiple subwoofers to your
110-120V~
system (see diagram).
