This receiver is equipped with DCAC (Digital 
Cinema Auto Calibration) function 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 
“Test Tone” (page 64).

Before you perform Auto Calibration, check 
the following items. 
• Set up and connect the speakers (page 18, 

• Connect only the supplied optimizer 

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

• Make sure the speaker output is not set to 

“SPK OFF” (page 9).

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

the optimizer microphone and the speakers 
to avoid measurement errors.

• Get accurate measurement by making sure 

the environment is free from noise and quiet.
