Sony 3-289-450-45(1) User Manual

 

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.

a)

• Adjust the speaker level.
• Measure the distance of each speaker from 

your listening position.

a)

• Measure the speaker size.

a)

• Measure the speaker polarity.
• Measure the frequency characteristics.

a)b)

a)

The measurement result is not utilized in the 
following cases.

– ANALOG DIRECT is selected.

b)

The measurement result is not utilized in the 
following cases.

– Dolby TrueHD signals with a sampling 

frequency of more than 96 kHz are being 
received.

– PCM signals with a sampling frequency of more 

than 96 kHz are being received.

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 

 

Before you perform the Auto Calibration, set 
up and connect the speakers (page 16, 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 
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.

• The Auto Calibration function does not work in the 

following cases.
– SPEAKERS (OFF/A/B/A+B) is set to off.
– Headphones are connected.

• If you activate the muting function during Auto 

Calibration, the muting function will automatically 
be set to off.
