The DCAC (Digital Cinema Auto Calibration) 
function allows you to perform automatic 
calibration as follows:
• Check the connection between each speaker 

and the receiver.

a)

• Measure the polarity of speakers.
• Measure the distance of each speaker from 

your seating position automatically.

a)

• Measure the speaker size.

a)

• Adjust the speaker level.
• Measure the frequency characteristics.

a)b)

a)

The measurement result is not utilized in the 
following cases:
– The multi channel input is selected.
– “2ch Analog Direct” is being used.

b)

The measurement is not utilized in the following 
cases:
– Dolby TrueHD signals with a sampling 

frequency of more than 96 kHz are being 
received.

– PCM signals with a sampling frequency of 

more than 96 kHz are being received. 

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 
“Making settings with the Test Tone menu” 
(page 66).

Before you perform the Auto Calibration, set 
up and connect the speakers (page 13-16).
• The AUTO CAL MIC jack is used for the 

supplied optimizer microphone only. Do not 
connect other microphones. Doing so may 
damage the receiver and the microphone.

• During the measurement, 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 the measurement in a quiet 

environment to avoid the effect of noise and 
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 obstacle from the 
measurement area to avoid measurement 
error.

• When you use a bi-amplifier connection, set 

“Sur Back Assign” to “BI-AMP” in the 
Speaker settings menu before you perform 
Auto Calibration.

• The Auto Calibration function does not work if 

– headphones are connected.
– SPEAKERS (OFF/A/B/A+B) is set to off.

• If the muting function has been activated before 

you perform Auto Calibration, the muting function 
will be set to off automatically.
