6: Calibrating the
appropriate settings
automatically
(Auto Calibration)
This system 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 system.
• Adjust the speaker level.
• Measure the distance of each speaker from
your listening position.
• Measure the frequency characteristics.*
* The measurement result is not utilized for signals
with a sampling frequency of more than 96 kHz.
The DCAC is designed to obtain proper sound
balance in your room. However, you can
adjust the speaker levels manually according
to your preference. For details, see "To adjust
the speaker levels" (page 63).
Before you perform Auto
Calibration
Before you perform the Auto Calibration, set
up and connect the speakers (pages 16, 20).
• 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 system 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
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.
Notes
• If the muting function has been activated before
you perform Auto Calibration, the muting function
will be set to off automatically.
• When you use the S-AIR product, disconnect the
headphones.
