Unfortunately Powersoft X series can deliver just very little fraction of their rated power, even for very short periods (few milli-seconds), also sustained power levels such as 480W/ch is very disappointing...
We have been expecting that Powersoft exploit the advantages of three phase operation just like PKN did while ago, however due lack of strong power supply and proper switching amplifier construction this has not happened. In the Powersoft X pack you get an amp with sub milli-second peak ability with a nice DSP but as soon as you need real power from the amp it collapses quickly which limiting its application to a narrow type of jobs. There is still only one serious three phase amp, the PKN 3PHASE-40K which can do several thousands of Watts per channel continuous for a minute or so (not 1ms..) when operated on 3x 380Vac. Expensive and gives its advantages in narrow range of *large* speakers what tolerates such power levels.. so I am not really surprised to see it just very few companies. |

Dave Rat has been using them for his full monitor setup for the Chillis everywhere too. 1x X4 to each wedge, and loves them. |

X series is on tour, it's used by Outline off the top of my head since launch amongst others. Cap Sound have racks of 3x X8 each

OK now you are at my level, having sex completely poverty mains connection. "no Neutral, it shrugged if off" if you were in a single phase scenario you would have lost your gig, it anyone working for me "lost a neutral" they would have lost there teeth as start, knees next, these amps may well be great but have never toured, so by my standards, never gigged. I know the Lab HPF series dominate touring now, but if you only have line array, quality left a while ago... FK Vero uses Lab Grup, but they do use bass solution to mitigate that, but again, not been on tour yet, so not a PA system, still a "Sound System". The tours I have been on, we carry MVAs of power, deliver to 2% and the ability to resolve comedysupplies (where my tooth hammer, get me the "sparks") is just so not relevant, even on small arena tours (IE all UK arenas) we see like 4% drift on line. I kinda wanna like PKN, but as i said, no pro demo stock, means they are not pro gear to me, I can "demo" crappy little Vi 7000 if I want ( and if I had forklift) but PKN are in this country at retail level in real terms. |

one of my demo racks spent many a gig on loan to reggae roast, it was there main rack on there stage at the v festival. Allso they have been used by a fair few systems at nottinghill over the past few years as well as many other roots reggae crews too..

Not quite that simple, the mains connector is wired differently for three, two or single phase usage but the amp basically doesn't care. One of ours had a bad neutral and we didn't notice til the gig was over, the amp just shrugs it off! The roadshow they did to launch them was fun, amp turns off to standby mode at 55v, and ran fine playing tunes up to 525v when it did the same thing. Then we ran it off DC. Then we ran it off a speakon connector coming out of a K20's Ch1 output, playing a 50hz some wave into the K20. Then we played having sex MICHAEL JACKSON into the K20 and the X4 still worked and played a different track through the demo PA. So yeah I can see why they're appealing to touring We run ours off single phase all the time, they're as efficient as any other Powersoft so it's fine - technically you could leave a 3ph cable on the amp and use a custom labelled jump lead if you're bothered. I think the PKN has a different wired connector too for single or three phase but it doesn't support quite as daft a range of power options as the distribution in X |

The PKN will do this too. But like others here I have never seen one.

It's great in theory and should helps loads with an even current draw, but problem is that you need to have 3 phase at every venue. People in large pro companies who could guarentee 3 phase at every gig will have a well known brand amp (or manufacturers own like d&b etc) for rider acceptability, and the people who may actually buy a PKN would play in all sorts of smaller venues where 3 phase is probably in short supply. Powersoft seem to have the best idea at the moment, their new X series amps are auto switching, they can take 3 phase in when you have it, but will auto switch to single phase if they detect that's the power they're plugged into.

And there is my point, if they do exist, I feel the need to play.
It is total comon sense, 240V is gonna cause a lot more current draw than 415V and to do 8K@ 8r you need 250V rails, so you are litterally pulled speaker current from the mains!!! |

I don't think I've heard of a real 3 Phase unit in use on a show. Do they exist properly?

Which is a pain as they don't have the 3 Phase babies in for demo use...
