Please login or register. The PA is getting bigger and I need a distro. Furman has one called the ACD It looks like what I need. Question though, what can I do as far as making up differant connectors to use in different venues that use different AC drops. Is there a list of common connectors with some identifying pics anywhere to be had.

I don’t believe any of the clubs around here use 3 phase drops. Many venues will not have any drops at all. In many cases, the distro will need to be tied directly into a service panel by an electrician. So make sure you have some bare wire tails. This plug also comes in a 3 phase version, but you will have to rewire the internal buss of the distro to use it in a 3 phase mode.
From the plug on the distro, I’ve got two 60′ sections of cord terminated with the Hubble plugs, and one 30′ section.
I’ll add as many as needed for the tap run. Then I’ve got one 5′ piece with a Hubble plug on one end and avd-100 wire tails to tie into a panel. If you’re lucky, some venues may have this Hubble plug already. In my area, the only place I’ve done sound that has these installed are the ballrooms at the Hollywood Park race track. The one downside to the ACD is that amps with high inrush current on power up Crest Pro series can trip the breakers easily.

You will need to turn these amps on with the breaker itself. I have two that I carry with me I find that most of the places I run sound at have 30 amp v appliance connections so I carry a 4 prong appliance pigtail and a 4 to 3 adapter. I also have a bare pigtail for having an electrician tie me in. I use 30 amp v twist locks for the pigtails. I only do small venues and underground type work so it may not apply to you. I think you are going to have troubles cad-100 any amp furmqn connections.
Before I buy a Furman ACD distro, I’d like your opinions
I imagine it is usually going to be a tie in. I’m curious about your 4 wire to 3 prong adapter. How is it wired? Mike Pyle Audiopyle Sound Dealer: If it’s a dual hot single phase V appliance tap with ground, that’s a different story, as long as you’re only running a V appliance off of it.
If you’re using the ground as a neutral, refer to the first sentence in this post. The 4 wire to 3 prong adapter is either a neutral tied to ground, a ground used as a neutral, or a lifted ground.
You don’t get safety with an arrangement like that. You get potential trouble. The only safe 3 prong receptacle for V 3 wire devices is one that is one leg of single or 3 phase system, with a single hot, a separate neutral and a separate ground, period. I’m telling ya’ the simplest and possibly the best distro for night clubs is mounting four or more Furman rack mount power strips inside a single rack.
Why does everyone seem to want a distro that requires large range outlets and hot lug tie-ins? Even if you use only four of the Furman 65 dollar “cheapy’s”, they each come with an installed breaker rated at 15 amps, and when combined with others in the same rack, they will deliver a total combination of up to 60 amps or more.
If you need 30 amps or more per volt circuit, then none of the following applies, especially in smaller night clubs. But for your 20 amp requirements, get some of their 20 amp models as needed.
You can draw up to 80 amps from four separate circuits! Each Furman unit has its own 20 amp breaker. Again, that’s 80 AMPS! Both of the above methods totally blows away needing any range outlet, or hot lug tie-in. Especially if you are forced to illegally wire up a 3 to 4 wire range adapter.
The coolest thing is, when all the Furmans are rack mounted in the same enclosure, all the building’s grounds force bond to zero Volts potential between them, right there at the rack mount chassis, reducing the chance of ground loops. Yank on those who always seem to find that handy outlet behind the stage curtain, not complying with the “all power comes from distro rule”! Hey, it’ll even illegally ground an ungrounded circuit.
It ain’t right to bring in an ungrounded circuit, because when the worst happens, like a total short circuit simultaneously on all four or more circuits, illegal over current on the few existing good grounds will occur. Just test all circuits, and bring in all grounded circuits.
Test for polarity too. I made my own 20 amp X four circuit distro using the same above principle, and it has proven itself over and over for a couple of years now in the most noisiest nightclubs ever known to man. At best, you could probably illegally “chop shop” a standard 3 phase breaker panel, and install three separate 20 amp extension cord feeders with three separated, isolated, floating un-bonded to chassis neutral busses, and one bonded ground bus bar, but why go illegal???
But you’d have “cool” breakers. My recommendation of using multiple Furmans or any other rack mount brand in a common rack chassis gets my vote.
And as powerful as you’ll ever need, just add more. Much better than being stuck with an illegal 60 amp 3 wire range circuit.
Why not make an equivalent unit like I described above, but in one package with breaker switches and power status lights. I used to agree with the multiple power strip deal I have found that most venues have lots of 15 amp outlets. However, finding enough acd-1000 Power can be tough. I really hated running a freakin zillion extension cords everywhere to get enough power. Usually the ground was bad or the circuit noisy.
Then there is the people factor. For me that was the last straw.
I did a gig that one of the power cords got unplgged 3 times. Then the lighting guy turned all his crap on at once and popped two of the breakers as we were apparently sharing the power on those two circuits.
I have found that having a distro has completely resolved all those headaches. I now have dedicated usually relatively clean power. After that gig, my electrician buddy and I sat down and started looking at what most of the places Furrman run sound at have.
I won’t comment on the three prong adapter, cad-100 eventhough we just run our own ground, it is still not code to tie in furmqn way.
I also suggest that anyone attempting to mess around with a distro talk to an electrician and have them look at all your connections, design, plug options etc. There’s no reason to use a rack full of Furmans if there’s a 30A or 50A recepticle on or near the stage.
Why run all that extra extension cord all over the room when you could just plug in one thing right on stage, and not have any issues with bad grounds, or voltage issues, etc. And also, with that Furman setup, if say a guitar amp had a bad ground, and was on another phase from the mixer, and things worked out like they sometimes do, that guitar player could end up with v running through his chest when he steps up to the mic.
Something to think about when you’re plugging in to random circuits. But maybe you’ve already thought of that, I don’t know. In any case, I think you should be prepared for both situations, since you’ll encounter them both. Carry a small distro, I got mine from http: And you should be also plan on the clubs that don’t have good power which you probably already have covered pretty well. In that case, something like the Furman rack thing is an OK idea, but I’m sure you can do something add-100 for less than 4 Furmans cost.
Adams wrote on Thu, 19 August It keeps the “jokers” guessing which breaker S we’re on when they decide to recycle our stage power for “last call”. Been there, and they’d done that But you are most likely talking about losing a common neutral from the neutral supply. In furan scenario nearly volts from one hot leg, to an oppositely polarized “swung-high” neutral during load imbalance, may appear across a Volt outlet. You’d also have to combine your scenario with another lost grounding conductor from its supply too, on that one “floating high” circuit load.
PLUS, add another combination of furmn shorted path between the neutral and ground on that “floating high” circuit’s load. PLUS, add on the fact that the other good circuit’s ground is and intact. Lot’s of combo’s, but hey, if I can picture it, it can happen.
Like I said, losing the one and only neutral supply, like on everyone else’s typical “breaker panel style” volt distro, and you’ve got killer voltage swings during imbalance. On the bright side, having 4 isolated hot and neutral conductors on my system gives us 4 isolated circuits.
Losing any neutral, except the building’s service entrance of course on any of my 4 circuits cannot swing the voltage up to volts like standard distros can. NOT on any of my volt outlets, it can’t, there’s is only Furmna dedicated to the one lost neutral. We could actually lose 3 out of the 4 grounds supplied, and still be grounded on all four circuits Now, I could think of scenarios where if I lose one ground from supply, and simultaneously short the floating ground and hot on one of my circuit’s loads, the most I can get is volts to good ground, not Of course do this again on an outphased circuit, and yes, I’ll getbut where do we stop.
I can touch and get shocked too. In any case, I think you should be prepared for both situations, since you’ll encounter them both And you should be also plan on the clubs that don’t have good power Hey by the way
