When your receiver or amplifier
is off, or is not sending program
material to the subwoofer, the
subwoofer will be in standby
mode. When the subwoofer
senses an audio signal, it will
automatically turn 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

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.
