Before you perform the Auto Calibration, set 
up and connect the speakers (page 15-18).
• 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.
– SPEAKERS (OFF/A/B/A+B) is set to off.

• If the muting function has been activated before 

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

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.
