9: Calibrating the
appropriate speaker
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, and measuring the
distance of each speaker from your seating
position automatically. Refer also to “Quick
Setup Guide” supplied with the receiver.
Before you perform the Auto Calibration, set
up and connect the speakers (page 14).
• The AUTO CAL MIC jack is used for the
supplied optimizer microphone only. Do not
connect other microphones. Doing so may
damage the receiver and the microphone.
• During the measurement, 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 measurement in a quiet
environment to avoid the effect of noise and
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 obstacle from the
measurement area to avoid measurement
error.
• When you use a bi-amplifier connection, set
“BI-AMP Speaker” to “ON” in the Speaker
settings menu before you perform Auto
Calibration.
