Setting the balance
You set the volume distribution between the left and right speakers using the Balance setting.
Setting the fader
You set the volume distribution between the front and rear speakers using the Fader setting.
Setting the loudness
increases the sound volume by increasing the bass.
This setting is especially suitable for low-volume settings and guarantees full bass reproduction.
SDV (speed-dependent volume)
The function automatically adapts the audio playback volume as a function of the vehicle's speed.
You can set the adaptation of the volume to the vehicle's speed on a scale from 0 (no increase in volume) to 5 (large increase in volume).
Surround (with Bose® sound system)
Activating achieves a sound setting with greater spatiality.
This permits the creation of a so-called virtual surround sound with conventional stereo sources such as CDs, radio, or MP3 formats, for example. The function can be set separately for the individual audio sources.
The function is generally activated with multi-channel sources such as 5.1 DVDs, for example.
It cannot be activated with the "AM" source.
