8: Calibrating the 
appropriate settings 
automatically
 
(AUTO CALIBRATION)
The DCAC (Digital Cinema Auto Calibration) 
function allows you to perform automatic 
calibration such as:
• Checking the connection between each 
speaker and the receiver.
• Adjusting the speaker level.
• Measuring the distance of each speaker from 
your listening position.
The DCAC is designed to obtain proper sound 
balance in your room. However, you can 
adjust the speaker levels and balance manually 
according to your preference. For details, see 
“9: Adjusting the speaker levels and balance 
(TEST TONE)” (page 35).
Before you perform Auto Calibration, install 
and connect the speakers (page 1718).
• 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. The volume of 
the sound cannot be adjusted. 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.
• When you use a bi-amplifier connection, set 
“SB ASGN” to “BI-AMP” in the System 
settings menu before you perform auto 
calibration (page 43).
Notes
• The Auto Calibration function does not work when 
headphones are connected.
• If the muting function has been activated before 
you perform Auto Calibration, the muting function 
will be set to off automatically.
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.
