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 frequency characteristics.

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 
“To adjust the speaker levels” (page 41).

Before you perform Auto Calibration, check 
the following items.
• Set up and connect the speakers (page 15, 

• Connect only the supplied optimizer 

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

• 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.

• 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 be shut off automatically.
