(AUTO CALIBRATION)

(Models of area code ECE, CEK,

AU1 onl y)

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.
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 “Adjusting
the speaker levels (TEST TONE)” (page 34).
Before you perform Auto Calibration, check
the following items:
• set up and connect the speakers (page 17,
19).
• connect only the supplied optimizer
microphone to the AUTO CAL MIC jack.
Do not connect other microphones to this
jack.
• turn off the muting function.
• disconnect the headphones.
• remove any obstacles in the path between
the optimizer microphone and the speakers
to avoid measurement errors.
• make sure the environment is quiet to avoid
the effect of noise and get a more accurate
measurement.
