Using 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 from
your seating position.
• Measure the frequency characteristics.
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
“To adjust the speaker levels” (page 41).
Before you perform Auto Calibration, check
the following items.
• Set up and connect the speakers (page 15,
17).
• Connect only the supplied optimizer
microphone to the AUTO CAL MIC jack.
Do not connect any other microphones to
this jack.
• Remove any obstacles in the path between
the optimizer microphone and the speakers
to avoid measurement errors.
• 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 be shut off automatically.
