Parametric Equalizer
In addition to the conventional Graphic
Equalizer, this unit has a parametric equalizer,
which allows you more precise adjustments.
By using each equalizer properly, you can
calibrate the unit more thoroughly.
Adjustment using this function requires
expertise.
When to Use Each Function
●
Parametric Equalizer
Use this to finely correct or improve the
frequency characteristics of the acoustics
of the car in order to establish a basis for
adjustments.
Practiced ears or a measuring equipment
may be required to apprehend the
problems of the sound field inside the car.
●
Graphic Equalizer
Use this to actively create an attractive
sound as conventionally.
Everybody can easily get the result through
trial and error of intuitive operations.
Even more effective adjustments are
possible when the basis is established by
using the Parametric Equalizer.

About the Parametric Equalizer
This system allows you to freely control the
filter, frequency, Q factor (acuteness) and
slope gain at 14 points consisting of 9 points
common for front/rear/subwoofer, 2 points for
front only, 2 points for rear only, and one point
for subwoofer only.
NOTE
• Configure the Parametric Equalizer to establish
the basis for adjustments before making
adjustments using the Graphic Equalizer.
• The changes made using the Parametric Equalizer
are not shown on the Graphic Equalizer screen.
• You can check the effects using the Parametric
Equalizer ON/OFF key.
About Adjustments

peaking filter to the left or right and search
the frequencies by ear. Studio engineers use
this method to make adjustments quickly and

cutoff frequency is a frequency for which the
output is -3 dB of the nominal passband value.
