"...do I have to actually load each song onto a CD or whatever and play it thru the PA and then adjust accordingly?"



Yes. You need not burn a CD, just play the MP3's through your PA and make notes of the songs you need to reduce/increase volume, reduce bass freqs on, etc. I start with all songs at -6 dB, then fine tune on the PA.


You can have the best monitors in the world, and your songs will not necessarily translate to a PA system. Two different animals. But then, you already found that out. smile
