6.9.3 _COMMON PROBLEMS DURING CALIBRATION
If the calibration tool plays more than 3 MLS bursts for a speaker, it means that it’s finding it difficult to
perform a reliable measurement of that speaker.
The most common warning messages are explained below:
• “Crest factor too low for capsules”:
• Check the Input Meters in the Processor/Meters page.
• If the Input level is null on at least one of the 4 channels, go back to the Optimizer Settings/Calibration page and
stop the calibration.
• Check that the selected analog physical input is selected in the Home/Select page.
• Make sure the microphone routing is correct.
• The microphone battery may be low. The red led at the front of the microphone indicates the battery level.
• The microphone or cable could also be damaged.
• “Unstable position for speaker”:
• Someone may have moved during the calibration.
• Too many strong reflections around the microphone environment disturb the impulse response measurement.
• An obstacle between the microphone and any of the speakers can disturb the measurement.
• The bandwidth of one of the speakers may be too narrow.
• “Unable to localize speaker”:
• Dipole/bipole speakers provide more than one wave at the same time, which can cause issues.
• Several speakers chained providing more than one wave at the same time.
