EQUALIZER

The position of the calibration micro- phone for Situation 1 (e.g. for the driver alone) is at the height of the driver’s head, approx. 10 cm next to the right ear.

For Situation 2, the calibration micro- phone should be positioned at head height between the driver and the front passenger.

For Situation 3, you should position the calibration microphone at head height in the centre of the vehicle interior (left/ right, front/rear).

Really quiet surroundings are required for the calibration. Any extraneous noise will distort the measured values.

The windows, doors and sunroof must remain closed during the calibration process. You should be seated in the driving seat throughout this procedure.

Note:

You can obtain the calibration micro- phone necessary for this from acces- sory retailers.

During calibration, the temperature in- side the vehicle must not exceed 55 °C since this could lead to falsified meas- urements.

The sound radiating from the loud- speakers must not be obstructed by any objects. All the loudspeakers must be connected. The microphone must be connected to the device.
