the ON position to use the
subwoofer. When your receiver
or amplifier is off, or is not

will be in standby mode. When
the subwoofer senses an audio

itself on. If the subwoofer does
not sense a signal after
approximately twenty minutes,
it will automatically go into
standby mode. If you will be
away from home for an
extended period of time, or if
the subwoofer will not be used,
switch the Master Power

The Phase Control
™
determines
whether the subwoofer’s piston-
like action moves in and out in
phase with the main speakers or
opposite the main speakers. This
is adjusted by pressing the button
to the 0°, or 180° position. The 0°
position of the phase button plays
the bass signal in phase with the
main speakers. The 180° position
plays the bass signal 180º, or out
of phase with the main speakers.
Proper phase adjustment depends
on several variables such as
subwoofer placement and listener
position. Adjust the phase switch
to optimize bass output at the
listening position.
Every system, room and listener is
different. There are no right or
wrong settings. This switch offers
the added flexibility to adjust your
subwoofer for optimum
performance for your specific
listening conditions without
having to move your speakers. If
at some time in the future you
happen to rearrange your listening
room, and move your speakers,
you should experiment with the
phase switch in both positions,
and leave it in the position that
optimizes bass performance for
your taste.
