![]() There are smaller versions of these like this one. Our electrician (I'm a contractor by day.) has installed huge versions of these in high-usage trading floor applications, where they'll charge them at night, and run all the computers off the batteries during the day for the clean, non-surgy, 100% reliable power under heavy usage. AC power can mess you up.įor small set-ups, like a Bose, one great way to do it is with one of the generators that use a converter operating off a couple of car batteries. Be safe, protect your gear, but above all. ![]() That goes for venues with normal wiring, as well as generators. With a digital mixer, I'd have it running on a UPS so it never saw the gennie power directly.įinal word of advice (and I'm not a licensed electrician so take all of this with a grain of salt), is don't do the gig if anything about the AC power supply smells fishy. That's not critical with traditional analog gear, but it can make a difference with some things. ![]() If you use any digital gear, especially something like a newfangled digital mixer, you might want to make sure the generator has a "true sine wave" output. I have one of those Furman power supplies with an LED ladder for voltage, which has been useful occasionally in diagnosing house power supply problems. There are power "conditioners" that include voltmeters, or if you know how to use a separate voltmeter safely with AC current you can check it yourself. It's more critical if you're in something like a rock band with kick drum sagging voltage in the amps and subs, but for an acoustic act this shouldn't be a big problem if the generator is reasonably well matched to your power draw. The main thing to watch for is under-voltage, typically caused by an undersized gennie that doesn't have enough mechanical stability (big flywheel) and electronic regulation to keep the voltage steady under surge loads. That will usually give you a clue about whether it's power you want to use, or not.Īssuming it's a legit operation, the next question is how much power does your gear draw? If everything will run off a single household 15 amp circuit without tripping a breaker, then you're probably okay with any reasonable commercial generator that's sized for a 15 amp load. Ask if the venue has passed a local code inspection, or has pulled a temporary event permit involving a code inspection (including the gennie). Find out if it's a licensed and insured outfit, or someone's Cousin JoeBob dragging out a gennie from his hunting camp. ![]() Same thing if the generator is supplied by another contractor and you're providing your own sound equipment. The first thing to do, is check with whoever is running the event and find out if the PA and generator are being supplied by a professional, licensed and insured sound company. ![]()
