Maybe because LabG & Camco representatives are not here spouting fairy tales about amplifier output powers ? <-- is Chris now a PKN dealer/rep? I'm sure that there is, however, a guy on here with a 'rootsy' and 'scoopy' background who sells them....

Has been said on here many times before, nothing special about the amps Roots dudes rate, they just want amps that do what they say on the tin. Wink

Crest 9001 wasn't targeted at Roots people, neither was MA5000VZ, MA3600, Lab FP14000, FFA10, Inf8MK2, QSC PL9.0, QSC PL6.0, CREST CA18, Powersoft K10. But guess what, they can pretty much drive either 4 ohms/2 ohm stereo, with HPF=35-45hz, without suffering apparent heart attack. Unlike "some amps", so Roots/Reggae dudes are buying these worldwide. <--- no, but none of those amps were field tested on a sound system before production commenced were they? Can't imagine the guys at Elkart saying "hold on, before we put our new amp (that we've spent $2 million+ to R&D) into production we'll send one to Hackney for testing...." Just so happens that they do the job they are asked to do by roots dudes, so it's a Thumbs Up for them, some amps don't, but it doesn't make the manufacturer a 'liar'  or the amps crap now does it? Which is the point I was trying to make.

If what you're saying is, why make amplifiers that can drive speaker loads published in specifications, for the inconvenient few, no problem. <--- this... what I was trying to get at is that published specs are obtained from controlled conditions, manufacturers expect the amps to be driven hard, but in decent conditions ie forced air cooling, decent power, decent cabling, realistic loading etc etc, ie by P.A. companies with large inventories and resources. 
 
 
Anyway as a side point, what happened to the days of custom amps? Used to love seeing big boxes in racks with no labelling and piles of XLR's - actually owned a few of them, right through to the pretty pretty Linx amplifiers with masses of flashing LED's!! Why has everyone gone 'commercial'?? Cost? Realiability? Weight?

The original post was from ceharden, just a general observation about the PKN amps based on some tests.
 
Peter from PKN has come in later in the thread. Ive not seen him spout any fairytales, he's just adding some technical information about the amps. In fact he does seem to have clearly stated that some of the PKN amps are optimised for maximum power into 4 ohms rather than 2 ohms.
 
Please also consider the possibility that English isnt Peter's first language, (he is from Budapest) so there may be some comments that are 'lost in translation', if his first language is not english.

Compared to some I dont think you've got at all carried away.. but I would tend to agree with you, this does seem to be a bit of competition to try to prove the Inf8 is better than the PKN - which isnt at all what this thread is about.
 
The point was to evaluate the PKN, and get some useful information about it across to people who are interested to find out a bit more about the amp and whether they are suitable for their needs.

What is your definition of standard/non standard music?

Without getting dragged into a full blown argument, I think he was being rather sarcastic there Sir....
 
But, you and I both know there is a certain amount of "brutal EQ'ing" in certain "arenas", and of late, when I demo speakers, I take my own, clear, flat and clean CD's with me as there does seem to be a lot of "ripped from Youtube" type disks on road at the moment that make the cleanest sounding drivers turn into nasty one note growlers.
 
The thing is, maybe the amp in question is not suited to the requirements of certain people, another group, on the other hand, may think that they are the best amps on the market. No one seems to rate Camco on sub, yet many big hire companies are doing five and six figure gigs with them!! This is whilst the man with a single "superior' amp may do three gigs a year of which he has to pay to appear at two of them!!!
 
I was in Southall, I heard all the amps, I have my opinions, I know what I liked the sound of... all the information is locked into my mental Rolodex and will be referred back to, if and when, I make an amp purchase.
 
Not so long ago 8001's were the amp, then CA18's and then 5000VZ's, the thing is, most of these were on the market and were in professional circles for years before being "discovered" as the most "superior" amp of the time. The PL9 has been banded about in recent times as superb and great -yet it was discontinued on the grounds of repeated 'ill health' 10 years ago. The web and forums like this have opened a whole new world up to the masses, we all now have access to information that was out of most peoples reach a few years ago - anyone can build a system now!!
 
Think about the scenario at Southall, a bunch of dudes brought an amp each (their bass amp) to the shoot out to test them; now if this was a big P.A. company doing 'some tests' the amp manufacturers would have been falling over themselves to send top of the line units to the test in order to win business. The roots market is an area most manufacturers have little or no time for (there are exceptions, I know!), why produce an amp targeted at them that will do this, that and the other.... and sell say 30 per year; on the other hand they could produce an amp that is good, it will do a bit of this, a bit of that and part of the other... and sell 300+ per year.
 
The Southall situation demonstrates the main thing that this argument keeps coming back to - roots dudes want an amp to 'smoke' or 'kill' any competition and impress the crowd with four scoops; P.A. dudes want an amp to produce a balanced sound for the music to be conveyed to the paying public so they can hear and enjoy it. Different scenario, different amps, different requirements. End of.
 
Let the dog go to sleep now and move on to test another amp.... If it's not for a certain market then so what..? Don't use them. No-one really uses Camco and Labs in the roots world and they don't really get slated very often - why target PKN? Big smile

36A @230Vac with PF>0.975  for few tens of seconds and then will limit and goes bellow 20A. The standard "blue" NEUTRIK Powercon is 20 (25)A rated. With "normal music material" the amp do not need more than 10-12A average.

The "Universal line" version has similar current on 230V but ~64A-72A on 115Vac with PF>0.96 for a half minute and then the current drops down to 32A (it has 32A "black" Neutrik Powercon)

These are the absolute maximum current draw values.

In parctical aspects I was able to operate a small system with 4x 1000W(8R) subs + 4x 800W(8R) tops from a XE6000+XE4000 powered by a single 16A ("B"-type fused) all in full power without problems, thanks to the PFC..

Your PM is not working. Please drop me a PM when you have a chance.

Lev, you should stop taking a crap on the PKN, ok? They dont deserve what you giving to them.
PKN's might not be right for your application, but i am sure inf8 i dont even want to touch with a shitty stick. So just stop it ok?
If is just not fair.
If you look at the amp shootout from like 5 years ago in the states made by the PSW forum members, the Labgruppen amp have blown after like 20 seconds. So that makes Labgruppen a shitty amp right?

Yo have proved your point and we get it. But why you not getting ours, is beyond me.

So what youre saying is you like the Inf8 V2 then?

Do you know anyone who does that ?

Sorry for the double post. Dumb smart phone posting before I had finished!!!! Peter can the 6000 go lower than 2.66ohms?
Thanks for the info CSG. Im just after a monster amp that can power 4 G subs or 8 scoops which sound as good as my heavies without breaking the bank.


Here the optimal loading range of XE/XD6000 are clearly visible:
