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

Model 203.0 /2 /7 as of 24.4.04 with CODE (527) COMAND APS with single DVD drive (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 

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

The settings which are selected for voice output during navigation also influence the 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 relative 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 sent to the speakers.

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

The volume is adapted to the noise level in the passenger compartment by GAL and the automatic vehicle interior noise adaptation feature DRO. In the process the vehicle speed signal and signal input to the sound amplifier microphone (B25/6) are used as a relationship indicator.
