Measurement details:
•
Distance is the distance of the speaker (in meters) to the measurement point;
•
Elevation is the elevation of the speaker (in degrees) to the measurement point;
•
Azimuth is the azimuth of the speaker (in degrees) to the measurement point;
•
Level A corresponds to the A-weighted level of the speaker;
•
Level C corresponds to the C-weighted level of the speaker;
•
Delay corresponds to the distance of the speaker;
• Bandwidth corresponds to the measured bandwidth of the speaker;
Correction details:
•
Level A Compensated corresponds to the A-weighted compensated level of the speaker;
•
Level C Compensated corresponds to the C-weighted compensated level of the speaker;
•
Delay Compensation is the delay that is added to every speaker to time align the system;
•
BM Delay may be added to the subwoofer to improve the crossover with the satellites. More rarely, if the
subwoofer is in advance, all the satellites are delayed;
•
Polarity specifies whether the system will invert the polarity of the speaker. Please note this is not the
“measured polarity” of the speaker;
•
Crest Factor helps evaluating the quality of the measurement. It should be higher than 30dB. Low values could
indicate background noise problems;
13.7 MULTI-POINT MEASUREMENTS (OPTIONAL)
For multipoint measurements, please see the chapter about performing multi-point measurements later in this manual.
13.8 COMPUTE THE OPTIMIZATION FILTERS
After the calibration is successfully completed, the Top Bar indicates NOT READY , which means no sound can go
through the processor until the optimization filters are computed.
