Adjusting the digital equalizer
Besides the automatic sound calibra-
tion, you can also manually adjust a
parametric 5-band equalizer.
In this case, parametric means that one
frequency can be boosted or reduced
(GAIN +8 to -8) individually for each of
the five bands.
The following bands are available:
● SUB LOW EQ 32 - 50 Hz
● LOW EQ 63 - 250 Hz
● MID EQ 315 - 1,250 Hz
● MID/HIGH EQ 1,600 - 6,300 Hz
● HIGH EQ 8,000 - 12,500 Hz
These bands can be set without the
need for measuring equipment. They
will allow you to significantly influence
the sound characteristics in your vehi-
cle.

are familiar with for making changes to
