You can use the sound of the sub woofer to suit
the sound source.
1
For models with a voltage selector, set
VOLTAGE SELECTOR to the local
power line voltage.
Depending on the model, the VOLTAGE
SELECTOR may differ.
* Saudi Arabian model: 120 – 127 V
2
Connect the power cord to a wall
outlet.
3
Press POWER on the sub woofer.
The indicator lights up while the sub woofer
turns on.
Press the button again to turn off the sub
woofer.
Note
To prevent speaker vibration or movement while
listening attach the supplied large speaker pads to the
sub woofer (page 10).
Adjusting the sound
You can adjust the sound of the sub woofer to
suit the sound of your front speakers.
Reinforcing the bass sound gives you a greater
sense of atmosphere.
1
Adjust the volume level of the sub
woofer.
Turn LEVEL control so that you can hear
the bass sound a little more than before. To
increase the volume, turn LEVEL control
clockwise. To reduce the volume, turn
LEVEL control counterclockwise.
2
Play your favorite song and movie.
Male vocal tunes and voice containing bass
sounds are most suitable for adjustment.
Turn the volume for front speakers to the
same level as usual.
3
Select the phase polarity.
Use PHASE selector to select the phase
polarity.
4
Repeat steps 1 to 3 to adjust for your
preference.
Once you have adjusted the sub woofer to
the settings you desire, use /–
on the remote (or VOLUME control on the
unit) to adjust the volume of the sub woofer
with that of the other speakers. You do not
need to adjust the sub woofer settings when
you change the volume level of the system.
Notes
• If GROOVE is set to “GROOVE ON” or
“V-GROOVE ON”, the sound may distort. Set
GROOVE to “GROOVE OFF” and adjust the sound.
• Do not turn the volume of the sub woofer to
maximum. Doing so may weaken the bass sound.
Moreover, extraneous noise may be heard.
• Selecting NORMAL or REVERSE with PHASE
selector reverses the polarity and may provide better
bass reproduction in certain listening environments
(depending on the position of the sub woofer and the
adjustment of the cut-off frequency). It may also
change the expanse and tightness of sound, and effect
the feeling of the sound field. Select the setting that
provides the sound you prefer when listening in your
normal listening position.
Tip
If bass response feels low, turn CUT OFF FREQ
control to adjust the cut-off frequency from
50 – 200 Hz (The default setting is 200 Hz.).
To make the most of the low level converter function
of Dolby Digital, turn CUT OFF FREQ control as high
as possible when playing back the Dolby Digital.
