Sony STR-DG1100 用户手册

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 14-17).
• 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 

“Sur Back Assign” to “BI-AMP” in the 
Speaker settings menu before you perform 
auto calibration.

• The auto calibration function does not work if 

headphones are connected.

• Cancel MUTING if it is set to on.

Place the optimizer microphone at your 
seating position. Use a stool or tripod so 
that the optimizer microphone remains at 
the same height as your ears.

• When a sub woofer is connected, turn on the 

sub woofer and turn up the volume 
beforehand. Turn the MASTER VOLUME 
knob to just before the mid-point.

• If you connect a sub woofer with the 

crossover frequency function, set the value 
to maximum.

• If you connect a sub woofer with an auto 

standby function, set it to off (deactivated).
