13.4 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.

It can also be the PP3 battery inside the microphone that is out of energy, the red led at the front of the
microphone indicates the battery level.

The microphone or cables 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 the speakers disturbs the measurement.

The bandwidth of one of the speakers is too narrow.

“Unable to localize speaker” :

Dipole/bipole speakers providing more than one wave at the same time

Several speakers chained providing more than one wave at the same time
13.5 CALIBRATION STATUS
The calibration status has 3 possible values:

Yes : If no problem occurred during the measurement. After calibration, the Top Bar indicates NOT READY,
which means no sound can go through the processor until the optimization filters are computed.
 Partial : If the calibration was stopped in the middle of the measurement process.

No! : When no measurement has not been performed.
