Volume/tone adjustments, function - GF82.60-P-2003TA

MODEL 211.0 /2 up to 31.5.06 with CODE (527) COMAND APS (with navigation) 

All volume/sound settings are performed in the COMAND operating, display and control unit (A40/3) and are transmitted via the MOST (Media Oriented System Transport) to the audio gateway control unit (N93/1).

The signal processing required for the volume and sound settings is performed via the audio component integrated into the audio gateway control unit (N93/1).

IMPORTANT The audio amplifier is located in the audio gateway control unit (N93/1). If the vehicle is equipped with code (810) Sound system, a digital sound processor enables additional stereo sound settings and an extended final amplification of the audio signals to be performed.

Volume setting 

The volume of whatever audio source is set can be adjusted using the rotary switch on the COMAND operating, display and control unit (A40/3). This can be adjusted separately in all audio and service areas (telephone, audio).

With the RESET function, the programmed settings for all sound parameters including volume can be selected and reset to the manufacturer default setting.

In the "Audio" menu, the difference between the volume of the audio signal and the voice output for navigation, voice control system (VCS) and traffic announcements can be adjusted. This means that voice output remains audible even in the case of loud audio output.

The volume of the voice output can also be changed during a voice output.

Tone setting 

The COMAND operating, display and control unit (A40/3) allows manual tone settings (bass, treble, balance, fader) for each audio source. Pressing the main button for the sound setting in the left panel area leads to the "Sound" menu, in which the desired settings can be made. They can be adjusted separately for each function (e.g. CD, radio reception, traffic announcements). The following sound adjustments are possible:

With a change in sound emphasis (balance, fader) the relative ratio of the volume of the individual speakers changes. "Balance" and "Fader" settings can be performed by pressing the main function key for sound distribution in the left control panel.

IMPORTANT Official emergency broadcasts have priority over all other audio sources. Settings made during navigation voice output apply as the absolute level for the subsequent navigation voice output.

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 to the sound amplifier microphone (B25/6) are used as a relationship indicator.

Mute 

If the user presses the "Mute" function key, the audio source currently being listened to is muted and the CD drives change to a pause status.
