Blaupunkt MP76 Calibrating DNC, Switching DNC off, Starting the DNC calibration

DNC

DNC

Dynamic Noise Covering

DNC allows for raising a volume when driv- ing that is considered pleasant for a non- driving vehicle.

The increase differs according to frequency ranges, dependent upon the noise develop- ment of the vehicle.

Hence, volume and sound remain at a pleasant level even with changing noise developments. Short-term noises, such as those while crossing railways, are not con- sidered.

Calibrating DNC

A calibration via the measurement micro- phone is required for vehicle-specific op- eration. The DNC calibration should be per- formed after the DSA calibration. Before the calibration, you should permanently attach the calibration microphone with the supplied Velcro tape near the console, but not in the floor area, at droning points or at the heating/ventilation.

The opening of the calibration microphone must point to the direction of the passen- ger compartment. The calibration should be performed at a quiet location with the engine switched off. The doors, windows and sunroof must remain closed, and you should be seated in the driver’s seat.
