I wrote a proposal for a homecoming set up this fall, and they are booking me for it. But since I'm used to doing smaller wedding oriented set ups, I'm not sure exactly what will be needed for this. The set up will end up being as follows:
- 4 QSC 181 Subs
- 2 Pioneer XPRS-12 tops
- K12 (run as a monitor)
- 2 Chauvet Intimidator 355 IRCs
- 4 Chauvet H6 SlimPar LED Fixtures
- My controller and laptop, etc.
The lights are all LED and should be pretty efficient. But I'm worried the subs would be too much for a single circuit. If I split the subs 2 x 2 on different circuits, do you think they'll blow?
I don't really know how to do the math, but would like to be a little more scientific than "just bring a crapload of extension cords"
Music is dynamic, and the only time that the amps in the speakers would require maximum input current would be on a test bench testing with sine waves. Music is equivalent to 1/8 power consumption ratings tested with pink noise. You would be ok with the items listed on two 15 amp circuits. Also remember that a 15 amp breaker is not going short burst of 15 amp draw. Some reading material is linked below.
