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 from 

your seating position.*

• Measure the speaker size.*
• Measure the frequency characteristics.*

* The measurement result is not utilized when 

 

“A. DIRECT” is selected.

The DCAC is designed to achieve proper 
sound balance for your room. However, you 
can adjust the speaker levels manually 
according to your preference. For details, see 
“Adjusting the speaker levels (TEST TONE)” 
(page 35).

Before you perform Auto Calibration, check 
the following items:
• Set up and connect the speakers (page 17, 

19).

• Connect only the supplied optimizer 

microphone to the AUTO CAL MIC jack.  
Do not connect any other microphones to 
this jack.

• Disconnect the headphones.
• Remove any obstacles in the path between 

the optimizer microphone and the speakers 
to avoid measurement error.

• Get accurate measurement by making sure 

the environment is free from noise and quiet.

• The speakers emit very loud sound during the 

calibration and the volume cannot be adjusted. 
Provide consideration to your neighborhood and to 
the children in presence.

• If the muting function has been activated before 

you perform Auto Calibration, the muting function 
will shut off automatically.

• The correct measurements may not be able to take 

or Auto Calibration cannot be performed when 
special speakers, such as dipole speakers are used.

If you connect front high speakers, select 
the speaker pattern that has front high 
speakers (5/x.x or 4/x.x) each time 
you perform Auto Calibration. 
Otherwise, the characteristics of the front 
high speakers cannot be measured.
