(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 listening position.
• Measure the speaker polarity.
. . *
• Measure the frequency charactenstIcs.
*
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 and balance manually
according to your preference. For details, see
"7: Adjusting the speaker levels and balance
(TEST TONE)" (page 30).

Before you perform the Auto Calibration, set
up and connect the speakers (page 14, 17).
• 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 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
o-et
a more accurate measurement.
b
• Ifthere 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
If
the muting function has been activated before you
perform Auto Calibration, the muting function will
be set to
off
automatically.
