1 Set the VOLUME control to minimum (0).
2
Turn on the power of all the other
components.
3
Make sure that the POWER switch is set to
the ON position, then press the STANDBY/
ON button to turn on the subwoofer.
* The Power indicator lights up in green.
4
Play a source containing low-frequency
components and adjust the amplifier's
volume control to the desired listening level.
5
Adjust the HIGH CUT control to the position
where the desired response can be
obtained.
Normally, set the control to the main speaker's rated
minimum reproducible frequency*.
The main speaker's rated minimum reproducible
frequency can be looked up in the speakers' catalog
or owner's manual.
6
Increase the volume gradually to adjust the
volume balance between the subwoofer and
the main speakers.
Normally. set the control to the level where you can
obtain a little more bass effect than when the subwooter
is not used. If the desired response cannot be obtained,
adjust the HIGH CUT control and the VOLUME control
again.
7
Set the PHASE switch to the position which
gives you the better bass sound.
Normally, set the switch to the REV
(reverse)
position. If
the desired response cannot be obtained, set the switch
to the NORM (normal) position.
8
Select "MOVIE" or "MUSIC according to the
played source.
MOVIE: When a movie type source is played, the low-
frequency effects are enhanced to allow the listener
enjoy more powerful sound. (The sound will be thicker
and deeper.)
MUSIC: When an ordinary music source is played, the
excessive
low-frequency components are out off to
make the sound clearer. (The sound will be
lighter and
reproduces the melody line more clearly.)
• Once the volume balance between the subwoofer and
the main speakers is adjusted, you can adjust the
volume of your whole sound system by using the
amplifier's volume control.
However, if you change the main speakers to others,
you must make this adjustment again.
• For adjusting the VOLUME control, the HIGH CUT
control and the PHASE switch, refer to "Frequency
characteristics" on the next page.
