2. Before you perform Auto Calibration

Before you perform Auto Calibration, check the following items:

  • Set up and connect the speakers.
  • Do not connect any microphones other than the supplied calibration microphone to the CALIBRATION MIC jack.
  • If using a bi-amplifier connection or a front B speaker connection, set the assignment for the SPEAKERS SURROUND BACK/BI-AMP/FRONT HIGH/FRONT B terminals properly.
  • Set the speaker output to a setting other than [SPK OFF].
  • Disconnect the headphones.
  • Remove any obstructions between the calibration microphone and the speakers.
  • For accurate measurement, make sure the environment is quiet and free from noise.


  • The speakers emit very loud sound during the calibration and the volume cannot be adjusted. Be considerate of your neighbors and any children who are present.
  • If the muting function has been activated before you perform Auto Calibration, the muting function will shut off automatically.
  • It may not be possible to take the correct measurements or to perform Auto Calibration at all if special speakers such as dipole speakers are used.
