7: Calibrating the 
appropriate settings 
automatically
 
(AUTO CALIBRATION)
This receiver is equipped with D.C.A.C. 
(Digital Cinema Auto Calibration) 
Technology which allows you to perform 
automatic calibration as follows:
• Check the connection between each speaker 
and the receiver.
• Adjust the speaker level.
• Measure the distance of each speaker to your 
listening position.
You can also adjust the speaker levels and 
balance manually. For details, see 
 
Before you perform the auto calibration, set up 
and connect the speakers (page 15–17).
• 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. 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 
correctly. Remove any obstacles from the 
measurement area to avoid measurement 
error.
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.
Tip
When you face the speaker towards the optimizer 
microphone, you will get a more accurate 
measurement.
