t

mately 10 minutes when no signal is detected from your system.The

Adjust Gain
Turn your Subwoofer-Level Control
¡
up to the halfway position.If no
sound emanates from the subwoofer,check the AC-line cord and input
cables.Are the connectors on the cables making proper contact? Is the
AC plug connected to a “live”receptacle? Has the Power Switch
§
been pressed to the “On”position? Once you have confirmed that the
subwoofer is active,proceed by playing a CD,record or cassette.
Use a selection that has ample bass information.
Set the overall volume control of the preamplifier or stereo to a comfort-
able level.Adjust the Subwoofer-Level Control
¡
until you obtain a
pleasing blend of bass.Bass response should not overpower the room
but r
ather be adjusted so there is a harmonious blend across the entire
musical 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,
e
xtending the r
esponse of the entire system so the bass can be f
elt as
well as hear
d.
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 is
nev
er obtrusi
ve.
Phase Contr
ol
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.
Crossover Adjustment
The Crossover Adjustment Control ¢ determines the highest frequency at
which the subwoofer reproduces sounds.If your main speakers can comfort-
ably 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 Adjustment
control to a higher setting, between 120Hz and 150Hz.
NOTE: This control will have no effect if the LFE/Normal Selector ™ is set
to LFE.If you have a Dolby Digital or DTS processor/receiver,the Low-Pass
Frequency is set by the processor/receiver.Consult your owner’s manual
to learn how to view or change this setting.
