Setting the equalizer

The acoustic characteristics of the car in- terior 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 ne- gatively by the resonance in the vehicle in- terior.

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 suppres- sed or boosted.

This car audio system is equipped with one (Biarritz RDM 169, Sevilla RDM 168) or two (Acapulco RDM 168) parametric filters. The first filter “LOW EQ” can be set from 32 to 500 Hz, the second filter “HIGH EQ” from 630 to 10,000 Hz. In this context, parame- tric means that it is possible to set the fre- quency 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 following table.

Notes on making the settings

The following notes are intended as recom- mendations only. They do not necessarily reflect your own personal sound prefe- rences.

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, treb- le, balance and fader to “0” and switch the Loudness function off, if necessary.

This setting is described in the Quick Refe- rence under 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”.

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 “DSC” to store your settings. You can switch the equalizer on and off in the “DSC” menu using the “EQ ON” or “EQ OFF” option.

Now you can compare the sound produced by your car stereo with or without the equa- lizer.
