■ Recalling equaliser curves
There are seven stored equaliser curves that
you can easily recall at any time. Here is a
list of the equaliser curves:
Equaliser curve
S.Bass is a curve in which only low-pitched
sound is boosted.
Powerful is a curve in which low- and high-
pitched sounds are boosted.
Todoroki is a curve in which low- and high-
pitched sounds are emphatically 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 equaliser curve
that you create. If you select this curve, the
effect is applied to all AV sources.
Custom2 is an adjusted equaliser curve
that you create. 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 "Todoroki".
p When "Flat" is selected, no supplement
or correction is made to the sound. This is
useful to check the effect of the equaliser
curves by switching alternatively between
"Flat" and a set equaliser curve.
