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 

 

Before you perform Auto Calibration, install 
and connect the speakers (page 14, 15).
• 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.

• 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.

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.
