location, location, location!!
What you need depends alot on how the event is setup. For example, if the two stages are like
___ ____
then you can use three
speaker stacks--one on each end and one in the middle, and use an Aux out to control one of them. If it's more like
\ /
then you have to have four stacks. Also, if it's the former then you can run one
FOH board. Each
stage has their own
snake going to you, and their own onstage
monitor board, say you have a 48
channel board, then great, channels 1-24 are S1, 25-48 are S2. Then you have a
monitor guy for each
stage, and you are set, my friend!
If it's the second one, then you have to have two of everything, because you will not be able to put one board in a good location to mix sound for both stages, and unless you happen to have a
speaker stack with a 100 or more degree dispersion, you cannot use one stack to
cover two stages.
Either way you are gonna need a buttload of mic cable!
And yeah, sorry, didn't feel like looking at your equipment list. If you don't have it, find a way to rent it, that's the way I look at it. You probably have a large board (like, 48+
channel FOH board) and depending on what you do (like if you are a rental
house then heck, you've got lots probably, a local place in my town has a buttload of small board that'd work for
monitor boards) you have several boards that would work as monitors too. Not sure how many channels you'd need, but for even a band, a 16
channel board should do you, that gives yuo say 8 drum mics and then 8 mics for vocals/channels for DIboxes.
say 2-4 subs per
stage, and then 2 mid/hi cabs per side means, depending on setup, you need either 3subs/3others, 6/3, 4/4 or 8subs/8others. Then lets say minimum of 4 monitors per
stage (three for front, one for drums, again, assuming a band), that means 8 monitors.
yeah it's alot of gear but it's probably also alot of money, and it might be alot of fun. Whatever it is, it'll probably be alot more fun two days after it's all over
very interested to see how they set it up, and how you run it all!
