I would say, I run my rig mainly for live music, not sat there near to clipping for DJ crap bouncing off the limiters.

I have heard if driven into clip they can cause havoc with the mains supply, but I haven't tried that game...

 

my view may be bias,

 

But ive spanked the ass off them from gensets to good and poor mains. Run a lorry full of em at nottinghill again last year. we even swopped another brand out for sae, as one of my teams amps just could not cut it vs the sae, he now has a full rack of em...

 

- Crest 8001 not enough headroom on the mids but good sounding 

- Matrix XT800 best sounding on coax tops but not enough headroom (one XT800 bridged per 4590 would be a winner)

- SS CA18 best on mids, loads of headroom, decent sounding

- PQM8 second best sound on coax, a bit harsher but I have since EQ'd the coax comps for the horn they are using so next outing will be interesting to hear the difference

- PQM8 perfect amount of power/headroom for BMS coax

- PQM8 Good sounding on mids, not as much headroom/clean power as SS CA18 but better transients.

Have not run PQM8 on subs yet. not had it too long. 

I can go to LMC or similar and get demo kit, but PKN have no presence in the UK.

Gut thoughts, 1U is a massive mechanical liability, the  3 phase connector is a joke, but as I have never heard a bad word about the sound I would like to try one.

The PQM13 rocks and Bee has a real "Pro" user thing going on, whilst I see PKN probably can't afford Bee on-line, they need to appoint a Uk pro dealer and equip them with demo stock.

Given support and market penetration, SAE all day.

5 years ago, we bought 10 pcs to try it on the field (we did 3 events per week on average). The plan was to make an OEM version of it. To be polite, it was not a flawless experience. In less than 6 months, 8 of them had problems (power supply, knobs, stay in protect mode, etc)

Sound wise, lot of background noise, very poor mid-high sound quality but deep warm and powerful bass (put Lab.Gruppen FP10000 to shame in this area). One of the very few switching amp that delivers what it says when powering subs.

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!!!

 

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. 

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

 

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.. 

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.

Very cost effective :-)
