Curious about line array coverage and throw
I’m an aspiring systems engineer, and I’m trying to learn as much as I can about line arrays whenever I get the chance.
I worked as a local stagehand with IATSE for the Noah Kahan tour a few days ago. They’re using GSL and KSL for mains. I was on the team flying the delays and I asked the tech who was leading the team how far the mains throw and he said about where the delays are. Makes sense. There were 24 boxes of GSL/side for the mains, and so the next day I tried to recreate the rig in arraycalc to see what it was doing. What I couldn’t figure out, though, was why the top boxes were almost parallel to the ground, with little to no splay. They were pointing at the upper seats of the 100s, wayyyyy overshooting the back of the floor. I know you’re supposed to overshoot a bit, but I didn’t think THAT much. I also know you need them to be tighter to couple, but what’s the good of a long throw couple if it’s pointed way past where you need it?
Also, trying to set the splay how they had it made the array way out of the safe rigging limit in arraycalc, so I’m not sure what the difference there was. They had 3 motors/side, so maybe that was the difference.
Also, for sub coverage — they had ground stacked subs along the front as well as flown LR stacks. What is the benefit of the flown stacks, other than just getting it off the ground and saving space?
Thanks!
