Adjust the parameters of each band for the
other speakers in the same way.
Note
A center frequency can be selected for each
band and can be changed in 1/3-octave steps.
However, the interval between the selected center
frequencies cannot be shorter than 1 octave.
Using the auto-equalizer
The auto-equalizer is the equalizer curve cre-
ated by auto TA and EQ (refer to
EQ (auto-time alignment and auto-equalizing)
on this page).
You can turn the auto-equalizer on or off.

Display the DSP function menu.
Refer to
Introduction of menu operations

You cannot use this function if auto TA and
EQ have not been carried out.

Auto TA and EQ (auto-time
alignment and auto-equalizing)
Auto-time alignment automatically adjusts the
time alignment according to the distance be-
tween the listening position and each speaker.
The auto-equalizer automatically measures
the car
’
s interior acoustic characteristics, and
then creates an auto-equalizer curve based on
that information.
WARNING
As a loud tone (noise) may be emitted from the
speakers when measuring the car
’
s interior
acoustic characteristics, never perform auto TA
or auto EQ while driving.
CAUTION
!
Thoroughly check the conditions before per-
forming auto TA and EQ as the speakers may
be damaged if these functions are performed
when:
—
The speakers are incorrectly connected.
(For example, when a rear speaker is con-
nected as a subwoofer output.)
—
A speaker is connected to a power amp de-
livering output higher than the speaker
’
s
maximum input power capability.
