Automatically calibrating the equalizer
You can electronically calibrate and store values for three different situations.
EQ 1 for the driver only
EQ 2 for the driver and front passen- ger
EQ 3 for the front and rear occupants
Hold the calibration microphone in the appropriate position whilst calibration is taking place.
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.
For situation 2, the calibration micro- phone should be positioned between the driver and the front passenger.
For Situation 3, it should be placed at the centre of the vehicle interior (left/ right, front/back).
Really quiet surroundings are required for the calibration. Any extraneous noise will distort the measured values.
Note:
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.
The microphone that you need is sup- plied with the Los Angeles MP74. If you have a Seattle MP74, you can obtain the microphone from retailers.
