Before you perform auto calibration

Before you perform the auto calibration, set up and connect the speakers (page 4).

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 amplifier and the microphone.

During the calibration, 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 auto calibration 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

1 Connect the supplied optimizer microphone to the AUTO CAL MIC jack on the front panel.

2 Set up the optimizer microphone.

Place the optimizer microphone at your listening position. Use a stool or tripod so that the optimizer microphone remains at the same height as your ears. Orient the L end of the optimizer microphone toward the front left speaker and the R end of the optimizer microphone toward the front right speaker.
