• The AUTO CAL MIC jack is used for the
supplied optimizer microphone only. Do not

volume of the sound cannot be adjusted. Pay
attention to the presence of children or to the

• 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

the characteristics of the front high
speakers cannot be measured.
Connect the supplied optimizer
microphone to the AUTO CAL
Set up the optimizer
Place the optimizer microphone at your
