(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 Auto
Calibration
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.

The Auto Calibration function does not work in the
