Anyone familiar with it?
Which figure i put in the signal selection? How many dbu? I cant get my head around the spl part of it.

ArrayCalc? Absolute SPL isn't really something I would rely on it for, resolution is pretty coarse at 1m only. Relative is good enough, no?

surely it kind of depends on how hot of a signal you plan to send the amps from the desk? you can fiddle with the input levels on the simulation tab anyway, and it should work out when GR will kick in/when its going to overload based on what you input.
as Toastyghost said though, arraycalc is great for relative levels, but its not really clever or granular enough to be used for really really detailed work. Noizcalc may also be worth a look at if you are mostly interested in the far field response of the system

It look like it is useless if you want to see how loud you can get.
There are 3 amps to chose from and they all give different power to the boxes.

Not really, ive not done anything too complex with arraycalc for ages, but you should be able to say what amp you want to hang everything off (possibly in the hardware tab), and then set the input level per box in the modeling tab.
Also don't forget that with d&b, using a meatier amp won't nessecarily actually equate to more power going to to the drivers, the d12 is something like 750w/channel, and that's already a hell of a lot of power for something like a q7, so the limiting will still kick in at the same point (just with more headroom left over) |
