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

MODEL 215, 220 with CODE (352) COMAND operating and display system with CODE (494) USA version 

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.

Audio sources are

• Radio
• Cassette player
• 6-disk CD changer

Service sources include:

• Telephone
• Voice output with navigation system
• Voice control system

The volume of voice output for navigation can be changed during voice output. In the process a difference between the volume of the audio signal and voice output of at least 12.5 dB is maintained automatically. This ensures that voice output remains easily audible.

Tone setting 

The COMAND operating, display and control unit (A40/3) can be used for different tone settings (e.g., treble, bass, balance, fader) for each audio source. The tone setting selected for the radio simultaneously applies to the traffic information radio channel message.

On vehicles as of 1.9.03, all audio signals of the audio components, voice signals as well as the signals of the navigation processor (N41/1) are transmitted via the Media Oriented System Transport (MOST).

Adjustments which have been selected for voice output during navigation also influence the voice control system with code (813) Voice control system (VCS).

Depending on the equipment installed, different sound patterns for optimization of the audio sources can be requested.

Sound adjustments without code (810) Sound system 

Bass and treble adjustment or acoustic patterns:

• Pop
• Classical
• Language

Sound adjustments with code (810) Sound system 

Bass and treble adjustment and sound optimization:

• Simulation of rooms (small, medium, large)
• Driver optimized
• Language

With a change in sound emphasis (balance, fader), the ratio of the volume between the individual speakers changes. The signal processing required for the volume/sound settings is taken over either by the audio component integrated in the COMAND operating, display and control unit (A40/3) or, with code (810) Sound system, the sound amplifier (A2/13).
