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
a)
and the receiver.
• Adjust the speaker level.
• Measure the distance of each speaker from
your listening position.
• Measure the speaker size.
• Measure the speaker polarity.
• Measure the frequency characteristics.
a)
The measurement result is not utilized in the
following cases.
– ANALOG DIRECT is selected.
b)
The measurement result is not utilized in the
following cases.
– Dolby TrueHD signals with a sampling
frequency of more than 96 kHz are being
received.

Before you perform Auto
Calibration
Before you perform the Auto Calibration, set
up and connect the speakers (page 16, 17).
• 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. The volume
of the sound cannot be adjusted. 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.
