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
system and to the wall outlet.

Switching the subwoofer ON

• Rotate SUBWOOFER VOLUME

clockwise until there is a click.
™ The LED indicator lights up in green.

Switching the subwoofer to
standby mode

• Rotate SUBWOOFER VOLUME

counter-clockwise until there is a click.
™ The LED indicator light turns red.

Repeat the adjustment for Volume and
Phase Polarity to suit your preference. Once
you have adjusted the subwoofer to the
settings you desire, use the VOLUME
control on the mini system to adjust the
volume of the subwoofer and the other
speakers. You do not need to adjust the
subwoofer settings again even when you
change the volume level of the mini
system.

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.
