Ok guys, here is a scenario :
Now I've just finished assembling my line array and here I am connecting them to the system .
I have a Behringer calibrated mic ECM 8000, a Real time analyser on my PC and an external sound card that is better than internal PC cards . At this stage I can generate sine waves , pink noise , white noise etc . Now What is the first crucial measure I should do and how to interpret it ? Let'g get this first answer cleared and understood by all amateurs interrested then we can pass to the next question !!!!!!!
Thanks
