Sony HT-DDW890 User Manual

 

This receiver is equipped with D.C.A.C. 
(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 to your 

listening position.

You can also adjust the speaker levels and 
balance manually. For details, see 

 

To avoid damaging the receiver and the microphone, 
be sure to use the supplied optimizer microphone 
only.

• You can also fix the optimizer microphone to a 

tripod (not supplied) and place the tripod at your 
listening position.

• Be sure to remove any obstacles in the path 

between the optimizer microphone and the 
speakers.

• When you face the speaker towards the optimizer 

microphone, you will get a more accurate 
measurement.
