8: Calibrating the
appropriate settings
automatically
(AUTO CALIBRATION)
The DCAC (Digital Cinema Auto Calibration)
function allows you to perform automatic
calibration such as:
• Checking the connection between each
speaker and the receiver.
• Adjusting the speaker level.
• Measuring the distance of each speaker from
your listening position.
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
“9: Adjusting the speaker levels and balance
(TEST TONE)” (page 35).
Before you perform Auto Calibration, install
and connect the speakers (page 17, 18).
• 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. The volume of
the sound cannot be adjusted. 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.
• When you use a bi-amplifier connection, set
“SB ASGN” to “BI-AMP” in the System
settings menu before you perform auto
calibration (page 43).
Notes
• The Auto Calibration function does not work when
headphones are connected.
• If the muting function has been activated before
you perform Auto Calibration, the muting function
will be set to off automatically.
