So, applying what I know about amps (2400 watts MAX with 120 volt wall socket) I called Behringer tech support to ask them how their new iNUKE NU6000 could produce such numbers. The only answer they had was what I thought they would say "switchable power supply and class D technology".

My question still stands: if the max you can get from a 120 wall socket and a 20 amp service is 2400 watts, how are they getting 6k from this amp? Is the answer, they're not?

Pixie Dust!

It's all a matter of measurement technique and energy storage. If both your conscience and the caps in the power supply are large enough you can get almost any number of watts out for a very short period of time. Power is really an instantaneous measure, even if we are usually interested in average power. So 6000 Watts at a single peak of a 20Hz wave isn't beyond the impossible. It's just continuously that it's impossible.

a simple response to that they are at 4 ohms 6000 w at 4 ohms are sort of 1500 w of ac power..... of course momentary power of that amount will only be possible in optimal conditions i mean try to hook 2 or 3 of these and get 6000w from each one of them..... besides of the usefulness of 6000w

Not continuous they aren't.

Part of the problem is that not every manufacturer measures the rating of their speakers or amps the same. More so in the speaker category but you can see it in amps as well. They were able to measure 6k watts our of that amp, what we dont know are the conditions.

I kind of figured that out after asking the question..lol. I remembered CONTINUOUS and PEAK. I tell ya what, I know a several local guy's running sound and while I'm a pup here, I'm a damn mentor to these guys. They simply don't "get it". They are running sound without a decent fundamental knowledge of how this stuff works and they don't even care to learn. Sad indeed.

Thanks for all the brilliant responses.

Behringer has ALWAYS been shady about their advertised power ratings. About the best you can do is go to a brick-n-mortar store that has it in stock and ask that the output voltage be measured before purchase. If they have nothing to hide, they shouldn't have a problem doing it for you.

I seldom see 20A breakers for the stage in clubs. They're usually 40A. Small bars, yeah, but you don't need mega-watts there, anyway.

It's nice living in the civilised 240v world...
