GF82.60-P-2003QM Volume/Tone Adjustments, Function
- with CODE (527) COMAND APS (with navigation)


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 (in menu "Settings") between the audio signal volume and the voice output volume is maintained automatically. This means that voice output remains audible even in the case of loud audio output.

Tone setting
Manual tone settings (treble, bass) can be made for each audio source on the COMAND operating, display and control unit (A40/3). The tone setting selected for the radio mode simultaneously applies to the traffic radio announcement.

Settings that have been selected for the voice output during navigation also influence the voice control system (with code (813) Voice control system (VCS)). In addition, the following 3 preset tone settings can be called up:
^ pop
^ classical
^ Language

With code (810) Sound system, the following tone optimizations are possible:
^ Standard
^ Ambient low
^ Ambient medium
^ Ambient high
^ 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 undertaken by the audio components integrated in the COMAND operating, display and control unit (A40/3). If the vehicle is also equipped with code (810) Sound system, the sound amplifier (A2/13) provides the final amplification of the audio signals, before they are output over the speakers.

Speed-dependent volume control (GAL) and Dynamic Range Optimization (DRO)
The volume is adapted in accordance with the background noise in the vehicle interior via the speed-dependent volume control and the automatic vehicle interior noise adaptation DRO. In the process the vehicle speed signal and signal input to the sound amplifier microphone (B25/6) are used as a relationship indicator.
