Slightly off-topic, but why on earth are you running 4/4 to FOH? Does your mixer pull 50 amps? Is it 1000' from the stage? Do you have massive lights out there?

I can't think of any other reasons to use 4/4 to FOH.
The Midas draws more current than my others boards. I have 3 power supplies. I also added a few other electrical things at FOH. I need a single cable that will reach up to 150' from front of stage and that means at least 160'. Then it has to connect to the main distro so figure 200'. It is single phase and that means 2 hot legs to a 50A breaker(not a 60A). The Midas is on one phase and everything else is on the other phase. With a 120V at the distro  the voltage will be 115V at the Midas on its phase with a 200' cable lenght from the distro with 4/4 cable. With 6/4 the voltage will be 112V. 4/4 cable is the way to go. 6/4 50' cable runs  on 45A breakers for the amp racks is plenty. I put my amps behind the speakers and that saves on copper and others things.

Can you run the Midas on 240V?  Half the voltage drop....

Thanks for that explanation. Just out of curiosity nosiness, how much power does the Midas draw? And do you have all 3 power supplies on at the same time?

Note Tim's response. Relevant to it, by using 240v you also get the benefits of running on balanced power, which many people spend $$$ to get from 120v. Using 240v you get them for free.

Sounds like you have a pretty cool rig.

Half the voltage drop....

It's better than that. Twice the voltage draws half the current, which causes one half the absolute (in Volts) voltage drop. But the voltage drop as a percentage of the line voltage is only one quarter and the energy loss in the line is one quarter, too, as P = i^2 * R. Increasing distribution voltage is a big win. -F

I dont know. I have to go to my storage unit and look at the power supply and see. If they will run on 220 it just means adding a 220 outlet to the FOH distro and thats easy.
