Setting the equalizer

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 EQ” can be set from 32 to 500 Hz, the second filter “HIGH EQ” from 630 to 10000 Hz. In this context, parametric means that it is possi- ble to set the frequency and either boost or reduce it (+10 to –20 dB) individually for each of these filters.

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 equalizer, set bass, tre- ble, balance and fader to “0”.

This setting is described in the Quick Refer- ence under 8 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 EQ filter, select HIGH EQ for treble and mid-range tones.

The “HIGH EQ” and “LOW EQ” filters can be set in the DSC menu:

•Press DSC.

•Press / as often as necessary until “HIGH EQ” or “LOW EQ” appears in the display.

•Press << or >> once and

•Set the level in the following table by pressing / .

•Press << >> to switch the frequency range.

•Press ENT to store your settings.

You can switch the equalizer on and off by pressing AUD for approx. 2 seconds.

Now you can compare the sound produced by your car stereo with and without the equalizer.
