Using the automatic sound
levelizer
During driving, noise in the car changes ac-
cording to the driving speed and road condi-
tions. ASL (automatic sound levelizer)
monitors such varying noise and automati-

becomes greater. The sensitivity (variation of
volume level to noise level) of ASL can be set
to one of five levels.

Using the equalizer
The equalizer lets you adjust equalization to
match the vehicle interior acoustic character-
istics as desired.
Recalling equalizer curves
There are seven stored equalizer curves that
you can easily recall at any time. Here is a list
of the equalizer curves:
Equalizer curve
S.Bass is a cur ve in which only low-pitched sound is
boosted.
Powerful is a curve in which low- and high-pitched
sounds are boosted.
Natural is a curve in which low- and high-pitched
sounds are slightly boosted.
Vocal is a curve in which the midrange, which is the
human vocal range, is boosted.
Flat is a flat curve in which nothing is boosted.
Custom1 is an adjusted equalizer curve that you cre-
ate. If you select this curve, the effect is applied to all
AV sources.
Custom2 is an adjusted equalizer curve that you cre-
ate. If you select this curve, the effect is applied to all
AV sources.
p This function is available only when main
audio is available.
p The default setting is “Powerful”.
p When “Flat” is selected, no supplement or
correction is made to the sound. This is
useful to check the effect of the equalizer
curves by switching alternatively between
