CCC audio system controller

The audio master collects all the audio signals in the vehicle, processes the audio signals and outputs them over 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 signals are transmitted to the loudspeakers in the following way:

• Front left and right (acoustic signals, telephone, messages from the navigation system, traffic information announcements)
• Front left and right, rear left and right (PDC signals)
• All loudspeakers (all sources in the "Entertainment" menu)
