rog,

heard a rumor that the new Kinetic and infinate void amps are going on sale v soon, if not already? this true?

Need 2000w a side into 3ohms to power 4 new labs. I'm sure you'l tell me why the infinate 7 is better than the 5k macrotechs?

Out of intrest, i would gues they are class H, and the kinetic are probably class T? Herad rumors of the prices, and they look great.

cheers.

Just got back from Plasa. It was great to meet you Rog.

The new amplifiers and systems set up in the demo room were awesome.

Yes, there was a 21in sub there, it is part of the new install system.

Very impressive :)

Jamie

Yeah, i have to agree, the clarity of the top end from those Stasys 3's was just amazing.

Yea, the infinate 8 looks like a beast. any idea about what/how many plugs it has and how many amps it pulls from the wall, as we often run things from Jennys. cheers.

would it be able to handle the 1.5ohm impedance?

The Infinites will only handle a minimum of a 2ohm load.

It would probrably just keep going into protect when you give it some stick. As you say, it depends on the circuity.

Only heard 1 lights worth of sound on the amps yesterday, i dare to think how it performs at full.

The amp won't need a 32A plug if driven with music. Music has at least 10dB crest, so the output is 10dB below the peaks. If it is a real good amp I guess it will do peaks of 4000W per ch at 2 ohms with 10dB crest giving you around 800W RMS. Let's say there will be even more peak output, so the amp puts out 1500W RMS with (typical) music signals and let's say the efficiency is 50%, so we get a input power of 3000W for a bad case. 3000W are 13A in Europe.

This 32A plugs are more a showoff thing. Only needed if you want to test the amp, not needed in realworld applications.

A generator is a whole other story. I recommend a generator twice the power rating you would need from a normal outlet. Generators won't handle the dynamic load that well, so they HAVE to be oversized.

BTW we work with LAB Gruppen fP6400 amps, rated 2x 2300W 4 ohms and 2x 3200W 2 ohms. No problems running two of them from one 16A outlet.... and they even have regulated SMPS (That means when voltage drops they simply draw more current to uphold power output.).

Just one point from what JD01 said '(That means when voltage drops they simply draw more current to uphold power output.)'. Voltage or current are, in theory, regardless because it's all to do with power. If the voltage drops and the drawn current rises to maintain output power, it can only do so if there is sufficient current available.

Also one other general point is that, for instance, 2000W amplifiers are not producing 2000W all the time, only for brief periods. Hence when they're plugged into a mains supply the peak current will get past the fuse or breaker, because they're designed to do that. And you therefore you can plug a big rack into a single 13 / 16 A supply.

Current isn't 'available'. Current is the result of voltage and the impedance. If there are 230V and a load impedance of 100 ohms you get a current of 2.3A, no matter what happens as long as voltage and impedance stay the same. if the voltage drops, the current drops with it. So voltage down to 200V = current down to 2A.

Voltage drops on AC lines occur because the line has an impedance too (wires) and this impedance will 'take' voltage proportional to the current the device powered by this line 'takes'. So if the line has an impedance of 1 ohm and the amp rack draws 10A the voltage drop on the line will be 10V = only 220V of the 230V will be available in this moment.

Regulated supplies 'see' that the line voltagfe drops and 'lower their impedance electronically' to draw more current from the line to compensate the lower voltage. Of course this will lower the voltage of the line even more, because more current is drawn so the voltage drop on the line grows.

Power BTW is as you surely know only the function of voltage x current. So at least with conventional amps and unregulated SMPS amps it's all about voltage and current....

The second part you said is what I said before....

6k of amps works fine off a 13a plug because of the type of music the system is used for, mainly commercial dance / pop. If we were to feed a sine wave at about 35hz through it for a while, then it would be a different story.

Hi,

Thanks for all the support and it was great to meet all of you.

On Tuesday and Wednesday I did get to turn hings up a bit. Well, quite a lot really. The loudest I measured was 146 dB.

The nInfinite range of amps doesn't come with any mains plug on it. Its just bare wires, so I don't know where this 32 amp CEE form as stardard is coming from. I put 32 amp CEE forms on mine just because I have distro baords with 32 amp outs. The amp will run from a 16 amp CEE form and I recommend you fit one. I have never triped a 16 amp breaker with a Infinite 8, but have only used one in to 4 ohms per side when it was on a 16 amp breaker. I have also used an Infinite 8 from a 13 amp wall socket. Again into 4 ohms per side. Its ok but if you are going to run 2 ohms per side then the fuse might blow.

Rog.

If you use cable and plug rated at 16a, then you use a 16a breaker. I would suggest 32a plug and breaker for heavy 2 ohm use.

Are Void products now banned from Earls Court? Hehe

Very impressed with the new products, will be in touch with PAP for more info and prices.

Jamie

I think a 16A breaker won't 'break' even at 2 ohms stereo as long as you run music. Yeah, I know, some music 'features' sequences of one tone bass only or even sine only, but they won't be at full level and they won't stay that long......

If you use a 16A CEE (or the blue ones) you could use a screw-in fuse (don't know their english name). Those will only trip by temperatur. normally a 16A screw will take a constand 16A current for more than an hour before tripping. And with dynamic loads you can easily pull 20A for short periods..... But I don't know if that's legal in all countries....

Another way: Use PowerCons. Small, handy and can handle more current than standard plugs.

How's the ceiling???

barry gibb - hahaha

Is there any chance i could get to hear Jesus's rig?

Not too sure when myself and the holy one will be using the rig next, having difficulty finding venues. Environmental health hate us now. If anyone knows of a good venue in the south west let us know. It needs to be big though, gone are the glory days of a few bodged scoops in the back room of a pub.

In fact, if anyone is promoting/organising and doing all the hard work, we might turn up (for a fee of course) and bash out some bass.

Its does look like Barry Gibb. Perhaps why they made such wonderful music?

don't you ever take the rig outside?

I'll see if I can come up with somewhere in swindon, what sort of cash are you talking about?

DIRTSOUNDBOY took two of our looney bins and I think 2 status 3's with a 3k generator and put it on a hill near stroud. That was pretty loud, but apart from that Notting Hill is the only time its all been outside. We would like too put it outside, but it at the moment its just too hard finding somewhere with power and not getting bummed by the police.

We'd like to get the rig that was at carnival and stick that in the glorious Swindon location of the Brunel Rooms, see how it compares to Valve.

word to that jesus - I like the lords attitude.

I *might* be able to sort something out for the shed room in brunel. Got a mate who's doing bits down there every now and then. I'll have a chat with him sometime this week and get back to you.

could prolly get a night in a pub in town too but last time we were there we got asked to turn it down and it was only 2 x Ohm 218s and a couple of mid/tops.

hmmmm.... we've done 9-10 free parties in wales and round my way this year..... but its getting a bit chilly in the eves now....we were going to knock the outdoor season on the head for this year...... next year though....i know an airstrip that can be done, amongst lots of other places(wales, lakes, dales too)....... with the divine sound system...... "hollier than thou sound clash"....got anyway of turning a plauge of bizzies into a field of weed or something? we had fookin' helicopters at the last one....turned out alright coz it gave uz ideas for fliers

mmmmm......many planz

......what about the west indian centre in leeds? irration steppas take a fair whack of system in there often....and the management don't give a f**k about, well, anything really......we've done the back room before but the main one...i fancy doing something there at some point....approximatly 100% non outside tho......with doors open maybe 98% non-outside.....hmmmm

yeah....u used to be able to get away with it in the back room early on.....but they crack down on it now-a-days.....it all got too gangster....lives being lost....families ruined.....you know how it goes....same old sad story
