Equalizer for Acapulco MP52
This unit is equipped with an automatic
digital sound calibration feature. It pro-
vides you with three self-calibrating 5-
band equalizers.
The USER1 - USER3 equalizers can
be calibrated automatically with the help
of a special calibration microphone. You
can obtain this microphone from your
Blaupunkt dealer.
The automatically ascertained values
can also be adjusted manually. If you
want to adjust the equalizer manually,
please read the section entitled “Adjust-
ing the digital equalizer”.
In addition, the unit is equipped with
sound presets.
