SUBWOOFER OPERATION
Press the Master Power
switch (marked “Power” å)
to the On position to use the
subwoofer. The CSS10 sub-
woofer will automatically
turn on or go into standby
(sleep) mode as described
below. When your receiver
or amplifier is off, or is not
sending program material
to the subwoofer, the sub-
woofer will be in standby
mode (the LED on the front
of the CSS10 will be red).
When the sub
woofer senses
an audio signal,
it will auto-
matically turn on (the LED
will be green). If the sub-
woofer does not sense a
signal after
approximately 20
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 switch å to
the Off position by pressing
it until it pops out.
VOLUME
Volume may be adjusted
using the Subwoofer Level
control
, as shown.
The Phase control deter-
mines whether the sub-
woofer’s pistonlike action
moves in and out in phase
with the main speakers or
opposite the main speakers.
There is no correct or incor-
rect setting. Proper phase
adjustment depends on sev-
eral variables, such as sub-
woofer placement and lis-
tener position. Adjust the
Phase switch ç to maxi-
mize bass output at the
listening position.
Remember, every system,
room and listener is differ-
ent. There are no right or
wrong settings; this switch
offers the added flexibility to
adjust your subwoofer for
optimum performance for
your specific listening condi-
tions without having to move
your speakers. If at some
time in the future you hap-
pen to rearrange your listen-
ing room and move your
speakers, you should experi-
ment with the phase switch
in both positions, and leave
it in the position that maxi-
mizes bass performance.
