Using the equalizer
The equalizer lets you adjust the equalization
to match car interior acoustic characteristics

Recalling equalizer curves
There are seven stored equalizer curves which
you can easily recall at any time. Here is a list
of the equalizer curves:

! CUSTOM1 and CUSTOM2 are adjusted
equalizer curves.

or correction is made to the sound. This is
useful to check the effect of the equalizer
curves by switching alternatively between
EQ FLAT and a set equalizer curve.

center frequency, an equalizer level and a Q
factor for each band.
! A separate CUSTOM1 curve can be cre-
ated for each source.
! A CUSTOM2 curve can be created com-
mon to all sources.
! The center speaker largely determines the
sound image and getting the balance right
isnt easy. We recommend reproducing a 2-
ch. audio (a CD for example) and getting
the balance right among the speakers ex-
cept for the center, and then reproducing a
5.1-ch. audio (Dolby Digital or DTS) and ad-
justing the center speaker output to the
balance you have already got among the
other speakers.
