Setting the equaliser
The acoustic characteristics of the car inte-
rior affect the quality of the sound repro-
duced in your vehicle to a much greater ex-
tent than the speakers.
Position, installation and the rear volumes
of, for example, the door or rear window
shelf all play an important role.
Even the sound produced by well selected
and installed speakers can be affected neg-
atively by resonance frequencies in the ve-
hicle interior.
As a result, the bass sounds may be lost or
reverberate, the mid-range tones sound too
overpowering and music instruments or
voices may be distorted or the total sound
quality may be completely lifeless.
The overall sound quality can be greatly
enhanced if certain frequencies are sup-
pressed or boosted.
This car stereo is equipped with 2 paramet-
ric filters. The first filter “LOW” can be set
from 32 to 500 Hz, the second filter “HIGH”
from 630 to 10,000 Hz. In this context, par-
ametric means that it is possible to set one
frequency for each of these filters and ei-
ther boost or reduce it (+10 to -20 dB) indi-
vidually.
These parametric filters can be adjusted to
very exact settings even without the help of
measuring instruments.
The individual steps you have to take to
make these settings are described in the
table.
Notes on making the settings
The following notes are intended as recom-
mendations only. They do not necessarily
reflect your own personal sound preferenc-
es.
We recommend that you use a music CD
you are familiar with to make the settings.
The CD should include tracks with different
instruments and vocals. Purely electronic
music is not well suited to serve as a basis
for making the settings because the original
sounds cannot be determined.
Before you set the equaliser, set bass, tre-
ble, balance and fader to “0”.
This setting is described in the Quick Refer-
ence under 9 AUD.
Now listen to the CD you have selected.
Evaluate the sound according to your own
personal preferences.
Now refer to “Sound impression/problem” in
the table and you will find suggestions to
eliminate any problems under “What to do”.
Make the settings for bass and the lower
mid-range tones with the LOW filter, select
HIGH for treble and mid-range tones.
The “HIGH” and “LOW” filters can be set in
the AUD menu, page 2:
Press AUD and NEXT one after the
other.
Select the filter you would like to adjust
(“LOW” or “HIGH”).
Press << >> to set the frequency.
Press
/ to set the level as described
in the following table.
Press ENT to store your settings.
