Location
The amplifier for the sound system is installed below the driver's seat.
Task
The amplifier for the sound system includes:
^
Linear amplifier stages
^
High resolution digital filter structures for the equalizer
^
Electronic circuitry for digital signal processing
The amplifier for the sound system operates using state-of-the-art digital signal processing technology. This means that it operates with the objective of
improving the acoustic tone characteristics for the audio range, audio tracks using mathematical algorithms. All input and control signals for the sound
system amplifier come over the Media Oriented System Transport bus (MOST). The amplifier for sound system is operated by the COMAND operating,
display and control unit (A40/3) and it also provides all the menus for user control.
Dynamic volume adaptation
The sound system amplifier is equipped with a dynamic volume adaptation feature. The interior noise is measured by a separate sound amplifier
microphone (B25/6) for dynamic volume adaptation. The volume is dynamically adapted to the interior volume level on the basis of the interior volume
measured. The sound amplifier microphone is located in the overhead control panel control unit (N70).
