hey I wasn't dis'g you or Dskys' knowledge - not at all. It's actually pretty decent when members share other knowledge here. Discussion is a good thing as long as it isn't blah blah knucklehead ramblings.
You've never delved into the depths of live audio (sound reinforcement) and listened to boneheads vs techno-gearheads argue db > amperage ratings for stadium coverage. It makes blood shoot out of my eyes listening to guys who know ABSOLUTELY nothing but theory and have never applied it to actual circumstance. I had 1 guy tell me temperature & distance made no difference for balanced audio performance in an open air stadium. As I'm sitting at the mix position in the Cotton Bowl surrounded by 60k+ fans in 95 defree heat - he told me it was the same as an 18k arena. "Oh OK, then I'll just leave 9 semi trucks of gear parked out in the lot - thanks for the tip - I'll let the JBL Vertek people know of the discovery - thanks, you DICKHEAD" (sorry about the size - I'm too tired to F$^# with it)
that's why I like UB, real folks w/real topics and good info and the occassional sidetrack.
