Before you perform AutoCalibration

Before you perform the Auto Calibration, set up and connect the speakers (page 14–16).

•The AUTO CAL MIC jack is used for the supplied optimizer microphone only. Do not connect other microphones to this jack. Doing so may damage the receiver and the microphone.

•During the measurement, the sound that comes out of the speakers is very loud. The volume of the sound cannot be adjusted. Pay attention to the presence of children or to the effect on your neighborhood.

•Perform the measurement in a quiet environment to avoid the effect of noise and get a more accurate measurement.

•If there are any obstacles in the path between the optimizer microphone and the speakers, the calibration cannot be performed correctly. Remove any obstacles from the measurement area to avoid measurement error.

Note

The Auto Calibration function does not work in the following cases.–Headphones are connected–SPEAKERS (OFF/A/B/A+B) is set to off.

•If you connect a subwoofer with a crossover frequency function, set the value to the maximum.

Depending on the characteristics of the subwoofer you are using, the setup distance value may be further away from the actual position.
