Audio system controller

The audio master collects, evaluates and controls all audio signals in the vehicle. The audio master outputs the signals in order of priority via the loudspeakers. The audio master also produces additional audible signals for warnings and for Park Distance Control (PDC). By mixing or fading in and out, a "softer" audible change is obtained between the signal sources.

The connection master distributes the signals of the audio sources and the audible signals to the loudspeakers. The connections to digital audio sources are made, disconnected and enabled by the connection master.

The signals are transmitted to the loudspeakers in the following way:

• Front left and right:

  Acoustic signals, telephone

• Front and rear: Signals from Park Distance Control (PDC)
• All loudspeakers: All sources in the "Entertainment" menu, traffic reports
