Using AUTO
CALIBRATION
(Europe, Australia and Taiwan
models only)
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 from
your seating position.*
• Measure the speaker size.*
• Measure the frequency characteristics.*
* The measurement result is not utilized when
“A. DIRECT” is selected.
The DCAC is designed to achieve proper
sound balance for your room. However, you
can adjust the speaker levels manually
according to your preference. For details, see
“Adjusting the speaker levels (TEST TONE)”
(page 35).
Before you perform Auto Calibration, check
the following items:
• Set up and connect the speakers (page 17,
19).
• Connect only the supplied optimizer
microphone to the AUTO CAL MIC jack.
Do not connect any other microphones to
this jack.
• Disconnect the headphones.
• Remove any obstacles in the path between
the optimizer microphone and the speakers
to avoid measurement error.
• Get accurate measurement by making sure
the environment is free from noise and quiet.
Notes
• The speakers emit very loud sound during the
calibration and the volume cannot be adjusted.
Provide consideration to your neighborhood and to
the children in presence.
• If the muting function has been activated before
you perform Auto Calibration, the muting function
will shut off automatically.
• The correct measurements may not be able to take
or Auto Calibration cannot be performed when
special speakers, such as dipole speakers are used.
