cables.Are the connectors on the cables making proper contact? Is the
AC plug connected to a "live" receptacle? Has the Power Switch

ing blend of bass. Bass response should not overpower the room but
rather be adjusted so there is a harmonious blend across the entire musi-
cal range. Many users have a tendency to set the subwoofer volume too
loud, adhering to the belief that a subwoofer is there to produce lots of
bass.This is not entirely true. A subwoofer is there to enhance bass,
extending the response of the entire system so the bass can be felt as
well as heard. However, overall balance must be maintained or the music
will not sound natural. An experienced listener will set the volume of
the subwoofer so its impact on bass response is always there but never
obtrusive.
Phase Control
£
The Phase Switch determines whether the subwoofer speaker's piston-
like action moves in and out with the main speakers, 0˚, or opposite the
main speakers, 180˚. Proper phase adjustment depends on several
variables such as room size, subwoofer placement and listener position.
Adjust the phase switch to maximize bass output at the listening position.

comfortably reproduce some low-frequency sounds, set this control to a
lower frequency setting, between 50Hz and 100Hz.This will concentrate
the subwoofer's efforts on the ultradeep bass sounds required by today's
films and music. If you are using smaller bookshelf speakers that do
not extend to the lower bass frequencies, set the Crossover Frequency
Adjustment to a higher setting, between 120Hz and 150Hz.
NOTE: This control will have no effect if the LFE/Normal Switch

Frequency is set by the processor/receiver. Consult your owner's manual
to learn how to view or change this setting.
