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 optimizer microphone to the AUTO
CAL MIC jack.
If using a bi-amplifier connection or speakers with a front B connection, set the assignment
for the SPEAKERS SURROUND BACK (FRONT B/BI-AMP/ZONE 2) terminals properly.
For details, see “Assigning the surround back speaker terminals (
SB Speaker Assign).”
Set the speaker output to a setting other than [SPEAKERS OFF]. For details, see “4.
Selecting the front speakers.”
Remove any obstructions between the optimizer microphone and the speakers.
For accurate measurement, make sure the environment is quiet and free from noise.
Note
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.
