[QUOTE="Bennett Prescott, post: 33193, member: 4"] Re: Prediction Software Matt, Those aren't options for SPL, those are options for bandwidth. I suspect the program is trying to give you "maximum peak SPL" or something similar, for which there is no definition. Your meter, with a 125ms integration time on "fast", is surely missing those peaks. Actual measured SPL will be highly dependent on program material, frequency range, and peak to average in that case. I agree with you that professional tools ought to deliver predictable results. This is unfortunately where we end up at the end of the number inflation game. How much QSC plays along I couldn't tell you since I've never used their products in a situation where it mattered.
