Parametric equalizer
Master Gain
If you feel the volume is too low, you can always increase the Master Gain. Have in mind that increasing the gain may cause the distortion. We do not recommend increasing the Master Gain more than 3 - 3.5 dB.
Important: in some cars such as Alfa Romeo Giulietta this setting should be always set to 0 dB or even less (depending on the source of the audio), otherwise this will definitely cause the distortion.
Bands
If you’re not satisfied with the available presets, you can configure Bank 1 preset manually. In total, up to 5 different frequency bands could be configured.
Every band has three controls. The first determines what specific frequencies you want to boost or cut: you zero in on a frequency somewhere between 20 Hz and 20,000 Hz, which you can then boost or decrease. The second, which is sometimes called the Q, determines the sharpness of the bandwidth (meaning “are you zeroing in tightly on one specific frequency, or are you targeting a wider bandwidth surrounding that frequency?”). And the third is the level control—by how much do you want to boost or reduce a frequency? We do recommend to use between 0.7 and 1 for Q setting and no more than 6 dB for G setting.
Filter type - use either PEQ (Parametric Equalizer) or Bypass the band. Other available filter types should never be used, since we don’t want to cut off any of the frequencies.
