Sony 3-283-375-11(2) User Manual

The table below shows the display when 
measurement starts.

* The corresponding speaker indicator lights 

up in the display during measurement.

When measurement ends, “COMPLETE” 
appears on the display and the settings are 
registered.

Disconnect the optimizer microphone from the 
receiver.

• Auto Calibration cannot detect the sub woofer. 

Therefore, all sub woofer settings will be 
maintained.

• If you have repositioned your speakers, we 

recommend that you perform Auto Calibration 
again to enjoy the surround sound.

• When Auto Calibration starts:

– Stand some distance away from the speakers and 

the listening position to avoid measurement 
failure. This is because test signals are output 
from the speakers during measurement.

– Avoid making noise to get a more accurate 

measurement.

• During the measurement process, the Auto 

Calibration is canceled when you do the following.

– Press ?/1 or MUTING.

SELECTOR on the receiver.

– Change the volume level.
– Connects the headphones.

process as follows:
