(AUTO
CALIBRATION)
The DCAC (Digital CinemaAuto 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 33).
Before you perform Auto Calibration, install
and connect the speakers (page
14,
15).
• 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.
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.
Optimizer microphone
1 Connect the supplied optimizer
microphone to the AUTO CAL
MIC jack.
2 Set up the optimizer
microphone.
Place the optimizer microphone at your
listening position.
You
can also use a stool
or tripod so that the optimizer
microphone remains at the same height as
your ears.
