7: Calibrating the 
appropriate settings 
automatically
 
(AUTO CALIBRATION)
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 to your 
listening position.
• Measure the speaker polarity.
• Measure the speaker size.
• Measure the frequency characteristics.*
* • DTS 96/24 signals are always played back as 48 
kHz when you correct signals.
• The measurement result is not utilized for 
signals with a sampling frequency of more than 
96 kHz.
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  
“8: Adjusting the speaker levels and balance 
(TEST TONE)” (page 39).
Before you perform the Auto Calibration, set 
up and connect the speakers (page 15, 16).
• 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 the calibration, the sound that comes 
out of the speakers is very loud. Pay 
attention to the presence of children or to the 
effect on your neighborhood.
• Perform the Auto Calibration 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 obstacles from the 
measurement area to avoid measurement 
error.
Note
The Auto Calibration function does not work in the 
following cases.
– ANALOG DIRECT is selected.
– Headphones are connected.
