7: Calibrating the 
appropriate settings 
automatically
 
(AUTO CALIBRATION)
This receiver is equipped with DCAC (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 Auto Calibration, install 
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 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 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.
Notes
• The Auto Calibration function does not work when 
headphones are connected.
• Make sure SPEAKERS (OFF/A/B/A+B) is not set 
to off.
