Correcting the subwoofer
’s phase
If trying to boost the bass output of the sub-
woofer doesn
’t do much or rather makes you
feel that the bass gets more murky, this may
indicate that the subwoofer
’s output and bass
content you hear over other speakers cancel
each other out. To remove this problem, try
changing the phase setting for the subwoofer.
1 Use MULTI-CONTROL to select FRONT
(speaker setting) in the audio function
menu.
Refer to Introduction of DSP adjustments on
page 52.
2 Press c or d to select SUB.W.
FRONT (front speakers) —CENTER (center
speaker)
—REAR (rear speakers)—SUB.W
(subwoofer)
—PHASE (subwoofer setting)
3 Press a to turn the subwoofer output
on.
4 Press d to select PHASE (subwoofer
setting).
5 Press a or b to select the phase of sub-
woofer output.
Press a to select NOR (normal phase). Press
b to select REV (reverse phase).
Note
When playing a 2-channel mono source with
Dolby Pro Logic II turned on, there may be occa-
sions when the following will occur:
! No audio is outputted if the center speaker
setting is SML or LRG and no center speaker
is installed.
! Audio is heard only over the center speaker if
installed and the center speaker setting is
SML or LRG.
Selecting a cross-over frequency
You can select a frequency, under which
sounds are reproduced through the subwoo-
fer. If the installed speakers include one whose
size has been set to SML, you can select a fre-
quency, under which sounds are reproduced
through a
LRG speaker or subwoofer.
1 Use MULTI-CONTROL to select HPF in
the audio function menu.
Refer to Introduction of DSP adjustments on
page 52.

adjusted.

—80—100—125—160—200 (Hz)
Note
Selecting a cross-over frequency is to set a cross-
over frequency of the subwoofer
’s L.P.F. (low-pass
filter) and that of the SML speaker H.P.F. (high-
pass filter). The cross-over frequency setting has
no effect if the subwoofer is set to
OFF and other
speakers are set to LRG or OFF.
Adjusting the speaker output
levels
Speaker level can be adjusted finely by listen-
ing to an audio output. First, use test tone to
adjust the approximate speaker level, and then
use this function to adjust finely.
1 Use MULTI-CONTROL to select FRONT-L
(speaker output level) in the audio function
menu.
Refer to Introduction of DSP adjustments on
page 52.
