Audio System Controller: Notes
In the past, each system used its own output media (e.g. gong, dual cone speakers etc) which generated a number of different sounds in the car. It was often not possible to achieve coordination between these sounds or at best, it could be done only in particular cases.
This created situations where acoustic information for other sources had to be suppressed, otherwise the driver would have been faced with a confusing mix of acoustic signals.
On the E65, a control unit has been developed to control, coordinate and generate acoustic signals according to priority: the Audio System Controller, (ASK).
The Audio System Controller (ASK) has three main functions.
- Network master
- Audio master
- Connection master
