Optimal sound reproduction

The audio system is pre-calibrated for optimal sound reproduction using digital signal processing.
This calibration takes into account factors such as the speakers, amplifier, cabin acoustics, the listeners' seating positions, etc., for each combination of vehicle/infotainment system.
There is also a dynamic calibration that takes into consideration the volume level, radio reception, and the speed of the vehicle.
The settings that are described in this manual, (Bass, Treble, Equalizer etc.) are only intended to enable the user to adapt sound reproduction to his/her personal tastes.
