I have noticed a huge difference in my system performance when I plug into an outlet that gives me a constant 120 volts plus vs one that shows 115-117 on my furman, mostly my subs peak much earlier Yamaha DXS15
There’s always more circuits... u just gotta find them. I bring 600ft of extensions so one way or another power is found lol. I’d rather have everything split and be safe, then put everything on one and risk popping breakersMany places I play I only get the option of one outlet, most have adequate power however there are a couple that when you plug in you get 115-117 volts
I mean I know power affecting equipment is a real thing, and have noticed it from time to time at higher volumes... but the difference is more noticeable when the starting voltage is a lot lower. It also depends on how many amps you're watts you're putting on a single circuit. If you have a lower starting voltage, you draw more amperage as opposed to if those same items have a higher starting voltage. Either way, the setups you guys see me do have between 2-4 circuits to make sure everything is nicely distributed so that even with low power I am still safe. Even my tops are separated from my subs to make sure I never draw too much amperage. If you're putting your entire system on one circuit with subs and/or lighting, you're probably getting very close to the limit, and even more so if you have less than 120v starting.

Correct, anything 25ft or longer is on a 12gauge cable... but likewise id rather have 4 circuits at 112volts than 1 at 120v. Keep in mind my productions are significantly different than most. Even a setup of 2 heads, 2 tops and 1 sub, requires 2 circuits.These long runs could also cause a voltage drop.
Larger gauge cables will help.
Yup that’s why the moving heads are the killers for me. 350w each... add tvs at another couple of hundred watts each, plus multiple laptops, accessories, etc... then you’ll easily need multiple circuits.Most power supplies today are tolerant of voltages from 80-130v, so low voltage shouldn't be an issue unless you have old school Class AB style amps with large transformers.
Even with my older Yorkville Unity system with its 3 PLX2 amps, I rarely drew over 8-9 amps total, so I have never had an issue with a single circuit for audio. Today's amps sip even less current, so unless you have a boatload of old style halogen PARs, it' unlikely you'd need much more than a single circuit unless you are doing a prom or have high-draw items like hazers and foggers and maybe multiple 200+w scanners/movers.
If anything else is on that circuit, then you'll see dips. Most equipment should be able to handle 110-130 swings.
+1Honestly, there should be NO difference between 120v and 115v .. Zero. If the circuit is shared with another load however, the current lag might be an issue.
