Before you perform the Auto Calibration, set up and connect the speakers (page 11, 14).
•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 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 to 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
If the muting function has been activated before you perform Auto Calibration, the muting function will be set to off automatically.
Optimizer microphone
1 Connect the supplied optimizer microphone to the AUTO CAL MIC jack.2 Set up the optimizer microphone.Place the optimizer microphone at your listening position.You can also use a stool or tripod so that the optimizer microphone remains at the same height as your ears.
Tip
When you face the speaker towards the optimizer microphone, you will get a more accurate measurement.
