JBL SDP-75 - Multi-Point Measurements (Optional); Compute the Optimization Filters

124
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.
