DNC - Dynamic Noise

Covering

Dynamic Noise Covering – masking of vehi-

cle noise.

When your vehicle is in motion, the DNC sys-

tem raises the radio volume to the volume

you consider pleasant when your vehicle is

stationary.

The volume is raised depending upon fre-

quency ranges and noise development inside

the vehicle.

As a result, volume and sound remain agree-

able even when vehicle noise changes. Short-

term noises, such as those arising when you

cross a railway track, are not taken into ac-

count.

Lining up DNC

For operation to suit your vehicle, the system

must be lined up using the special micro-

phone. Please do not line up DNC until you

have aligned the hifi. The microphone should

be permanently mounted near to the console

using the self-adhesive tape provided, how-

ever not in the leg area, in resounding places

or near the fan/heater vents.

The microphone mouthpiece should point

towards the passenger area. It is best to line

up the system in a quiet place with the en-

gine switched off.

tivity with which the volume and tone are
