Equalizer setting

The sound in the vehicle is influenced deci- sively by the acoustic characteristics of the passenger compartment, substantially more than by the characteristics of the loudspeak- ers.

The position and installation of the loud- speakers and the volume to the rear, for ex- ample of the door or rear shelf, are howev- er also important.

Even when suitable loudspeakers have been selected and installed properly, reso- nances in the passenger compartment may have a detrimental effect upon the sound.

This can result in the bass frequencies booming or being absent, mid-frequencies encroaching excessively, musical instru- ments or voices being strongly distorted, or the sound generally being muffled.

The subjective sound impression can be improved considerably by suppression or amplification of certain frequency ranges by the car radio.

This unit is equipped with two parametric fil- ters. The first filter, “LOW EQ”, can be ad- justed from 32 to 500 Hz, the second, “HIGH EQ”, from 630 to 10 000 Hz. In this case, parametric means that one frequency can be increased or reduced for each of the two filters (+10 to -20 dB). The bandwidth/qual- ity of the two filters can also be adjusted.

The parametric filters can be adjusted ex- actly without instruments.

In addition, you can select from seven pre- programmed equalizer settings, which are adjusted for different musical styles. Refer to the “Selecting pre-set sound settings” section.

The steps required for adjustment are de- scribed in the table.

Adjustment instructions

The instructions below represent a recom- mendation only. You can adjust the sound characteristics according to your own per- sonal preference.

We recommend that you use a familiar mu- sic CD for adjustment of the filters. The MD/ CD should include tracks with a range of in- struments and voice. Pure electronic music is not suitable for evaluation purposes, since the original sound is not known.

Before adjusting the equalizer, set the bass, treble, balance and fader to “0”.

This setting is described in the condensed instructions under 8 AUD.

Now listen to the MD/CD with which you are familiar.

Evaluate your impression of the sound ac- cording to your taste.

Now read the “Tonal effect/problem” column in the table, and look for solutions under “Measure”.

Use the LOW EQ filter for settings in the bass and lower mid-range, and the HIGH EQ filter for the treble and upper mid-range.

The “HIGH EQ” and “LOW EQ” filters can be adjusted in the DPE menu:

•Press DPE to call up the DPE main menu.
