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

MODELS 203.0 /2 /7 up to 23.4.04 with CODE (352a) COMAND operating and display system with CODE (491) U.S. version 

With reference to the COMAND, operating, display and control unit (A40/3) a distinction must be made between audio sources and service sources.

Audio sources are:

• Radio
• CD player

Service sources are for example:

• Telephone and voice control system (VCS) (code 813).
• Voice output with navigation system

Volume setting 

Changing the volume of an audio source has an identical effect on all other audio sources. The volume is also jointly regulated within the service sources in the same manner.

The volume of voice output for navigation can be changed during voice output. An adjustable interval is automatically maintained (in menu "Settings") between the audio signal volume and the voice output volume. This means that voice output remains audible even in the case of loud audio output.

Tone setting 

The COMAND operating, display and control unit (A40/3) allows manual tone settings (bass/treble) for each audio source. Selected settings for voice output during navigation also influence the voice control system (VCS) (code 813).

In addition to this the following tone settings can be invoked with code (810) sound system:

• STANDARD
• Ambient small
• Ambient medium
• Ambient large
• Language
• Driver optimized

With a change in sound emphasis (balance, fader) the ratio of the volume of the individual speakers changes. The signal processing required for the volume and tone settings is done by the audio component integrated in the COMAND operating, display and control unit (A40/3). Final amplification of the audio signals is accomplished by the sound amplifier (A2/13).
