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 listening position.

The DCAC is designed to obtain proper sound 
balance in your room. However, you can 
adjust the speaker levels manually according 
to your preference. For details, see “Adjusting 
the speaker levels (TEST TONE)” (page 34).

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

• connect only the supplied optimizer 

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

• turn off the muting function.
• disconnect the headphones.
• remove any obstacles in the path between 

the optimizer microphone and the speakers 
to avoid measurement errors.

• make sure the environment is quiet to avoid 

the effect of noise and get a more accurate 
measurement.
