(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.
You can also adjust the speaker levels and
balance manually. For details, see
"7: Adjusting the speaker levels and balance
(TEST TONE)" (page 33).
Before you perform Auto
Calibration
Before you perform Auto Calibration, install
and connect the speakers (page 13–15).
• 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. 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.
Note
The Auto Calibration function does not work when
headphones are connected.
