Task
The sound system amplifier control unit is connected to the Media Oriented System Transport (MOST) and amplifies the audio signals. The sound
system amplifier control unit manages all the audio sources integrated into the vehicle and processes their audio signals. The audio signals are output
over the following speakers:
^
Left front door speaker (H4/1)
^
Right front door speaker (H4/2)
^
Left rear door speaker (H4/3)
^
Right rear door speaker (H4/4)
^
Center instrument panel speaker (H4/27)
^
Bass speaker (H4/29)
^
Left rear surround speaker (H4/54)
^
Right rear surround speaker (H4/57)
These are discretely connected to the sound system amplifier control unit. The sound system amplifier control unit increases and reduces the output level
of the audio signals (Dynamic Range Optimization (DRO)) depending on the noise level in the vehicle interior. The noise level in the interior
compartment is measured via the sound system microphone (B25/6) discretely connected to the sound system amplifier control unit.
