SUBWOOFER
• Install the subwoofer wherever you like
because with the bass sound range
reproduced from the subwoofer (below
150Hz), human hearing cannot detect
the direction and position in which the
sound is being produced.
• Also, since the feeling of stereo is lost
with bass frequencies, a single
subwoofer is enough for reproducing the
bass of stereo channels. However, you
may install more than one subwoofer if
your system has more than one
subwoofer out jack.
• To obtain a better bass reproduction, we
recommend that you install the
subwoofer on a solid floor where
resonance is unlikely to occur.
• Always place the subwoofer vertically,
keeping a few centimeters from away
the wall.
• Do not place an object on the subwoofer
or sit on it.
• If the subwoofer is placed in the center
of a room, the bass could be extremely
weakened. This is due to the influence
Setting up the Subwoofer
of the standing wave of the room. If
this happened, move the subwoofer
away from the center of a room or
eliminate the cause of the standing
wave, by installing a bookshelf on the
wall, etc.
Important:
Before you operate
the subwoofer,
complete the
preparation
procedures.
Switch on your
mini system and
select the sound
source.
AC Power Supply
After all other connections have been
made, connect the AC power cord to the

Volume Adjustment
You can adjust the subwoofer to suit the
sound level of your front speakers.
Reinforcing the bass sound gives you a
greater sense of atmosphere.
1 Adjust the VOLUME on the mini system
until the sound from front speakers is
not distorted. If it is distorted, the sound
from the subwoofer will also be
distorted.
2 Play your favourite songs. Male vocal
tunes containing bass sounds are most
suitable for adjustment.
3 Adjust the SUBWOOFER VOLUME to
determine the loudness of the bass
sound from the subwoofer.
Phase Selector
Use PHASE
SELECTOR
located at the
rear of the
subwoofer to select the phase polarity.
Selecting the polarity at either 0˚ or 180˚
may determine better bass reproduction
effect in certain listening environments
(depending on the type of front speakers
and the position of the subwoofer). It may
also change the expense and tightness of
sound, and affect the feeling of sound field.
Select the setting that provides the sound
you prefer when listening in your normal
listening position.
