- with CODE (525) MB Audio 50 APS radio
- with CODE (511) Audio 50 APS with DVD changer


In vehicles with code (810) Sound system, the functionalities for the volume and tone settings as well as for the amplification of the audio signals run in the sound system amplifier control unit (N40/3) before the audio signals are output via the speaker system. In vehicles except code (810) Sound system, the functionalities for the volume and tone settings as well as for the amplification of the audio signals take place within the radio with auto pilot system (A2/56).

If the vehicle is equipped with code (810) Sound system, additional stereo sound settings and an extended final amplification of the audio signals are possible.

Operating instructions
The volume and tone settings can be performed via the following components:
^ Using the buttons + and - for setting specific functions and volume control (S111s1) on the multifunction steering wheel (MFL)
^ Using the rotary switch of the radio with auto pilot system

The volume and tone settings are shown on the Audio/ COMAND display (A40/8). The volume setting can be carried out separately for each audio source. Predefined settings can be selected and reset to the manufacturer default setting via the system settings.

Tone setting
The radio with auto pilot system allows manual tone settings (bass, treble, balance, fader and tone options) to be made for each audio source. The selection is made and settings can be performed using the Audio/COMAND control panel (A40/9). The required tone settings can be performed via the "Sound" menu. They can be adjusted separately for each function (e.g. CD, radio reception, traffic announcements). Vehicles with code (810) Sound system additionally have the following tone options through the sound system amplifier control unit:
^ Surround
^ Ambient

If the tone emphasis is changed (balance, fader) the volume relationship between the individual speakers changes relative to each other. The "balance" and "fader" settings are called up by pressing the Audio/COMAND control panel for sound distribution on the Audio/COMAND display.

Speed-dependent volume control (SDV) and Dynamic Range Optimization (DRO)

Speed-dependent volume control (SDV) and dynamic range optimization (DRO) are used to adapt the volume to the noise level in the vehicle interior. In the process the vehicle speed signal and signal input at the sound system microphone (B25/6) are used as relationship indicators.
