EQUALIZER
Equalizer
This car radio is fitted with a parametric
digital equalizer. In this case, paramet-
ric means that for each of the five fil-
ters, one frequency can be individually
raised or lowered (GAIN +8 to - 8).
The following filters 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 filters can be set without meas-
uring equipment. This means that the
sound quality inside the vehicle can be
greatly influenced.
Notes on adjusting the equalizer
We recommend you use a CD you are
familiar with when adjusting the equal-
izer.
Before adjusting the equalizer, set the
tone and volume balance to zero and
deactivate the loudness function. To do
this, please see the chapter Tone and
volume balance.
Listen to the CD you have chosen.
Evaluate the tone impression ac-
cording to your taste.
Now consult the chart Sound im-
pression section of An aid to ad-
justing the equalizer.
Set the equalizer values as de-
scribed under What to do.
