It's too bad nobody seems to care about this amp. Does anyone even own one? Haven't even heard the name spoken for a year now.

Me either. I wanted to see a non DSP version tested. I didn't care about the DSP version because I knew it would have software bugs and limiter problems. I'm still curious to see what the non-dsp version can do.

Well, final word on the performance was unimpressive, right? Marginally more power than a NU6000 though 2-ohm capable, but much more expensive...

What was found is that the software was limiting the full amount of voltage swing it could possibly produce.

Nothing ever came of that 'fix'.

Whenever you want. If you want to bring something I'll test it out. I'm finishing up some testing on the QSC PL236 and NU4-6000 this weekend. Also have an NU1000DSP, mini-x a100, and some other crap amp to test.

I want someone with an FP14k, newer version, to bring it by at some point. Friggen health issues set me back :/

And Auburnu008's recent thread is just one of legions of bass-loco's around here. From dedicated drops from transformers, to dual G-horns in the attic...nothing surprises me here anymore. In awe, jealous, impressed, blown away by some - but not surprised.

What have you tested and Doc'd so far? I saw that you were getting the gear together and starting up but never heard anything. Definitively interested and wouldn't mind sending you some gear if the turn around was fairly quick. We need this with so many choices today.

Auburn's is a dual purpose theater. When he's not using it to watch movies, Chevron uses it for Hydraulic Fracking.

Price on Inuke 12000DSP has dropped to $800

Price on INUKE 12000 has dropped to $700.

I don't give a hoot's nanny about DSP because it places more things which can go wrong on a already cost compromised unit. So the testing of the DSP version of the 12000 holds no bearing to me. However I am thinking about purchasing the non-DSP version of the 12000 if someone can test it. I still want to know what this amp puts out without any voltage limiter bs or any other DSP software related issues.

I and others would like to know as well.


I'm with you on the DSP thing. It just makes things more simple and clean for those that want the power but simplicity. I, on the other hand, have a ton of external DSP power (3x DCX's) and I don't really care for built-in DSP either but... there are reasons for them existing.

from the spec sheets.


6000 which bench at about 1800 watts both channels at 30hz



12000, if it clocks the same multiple, could be 3900 watts both channels driven at 30hz
then again, that implies something like 65 amps on 120v, hhmmm.

Not according to notynt's results. He got 1200w x 2 into 4 ohms (two pairs of bridged channels).

The 3000 was tested http://www.diyaudio.com/forums/class...surements.html
to get around 2000 bridged into 4 ohms.

Isn't the 6000 just two 3000s built into the same skin? If it really only puts out 1200 then we might be better off getting two 3000s instead. And that would give you many more configuration options.

With current pricing, and that 1200 watt rating, the 3000 offers 7.14 watts per dollar, and the 6000 offers 6 watts per dollar.

The 6000 would need to deliver around 1500 watts per channel to equal the value of the 3000, assuming that 3000 test was done properly.

It's possible the power supply in the 6000 isn't really double the capacity of the one in the 3000. notynt indicated he plans to measure the 3000 so we'll see how it compares soon enough.

And someone else's tests said the NU6K was good for 1800W in subs, not 1200W.

Meh.

I somehow doubt the 3K will do 2000W.

I haven't seen that test. Did that tester drive two 4 ohm loads, or just one? Notynt was using all 4 channels (bridged to 2 channels). Both driving 4 ohm loads. He measured one of the two. It's possible if he was only using 1 channel he would have gotten more power.

yeah...different testing methods yield different results. i was referencing the 33% duty cycle 30hz number.

"Now if these amps were class-AB/H/G etc. with 50Hz transformer based supplies then measuring power output is normally easy, just use a continuous tone and measure what you get. As we know amps with switching power supplies sometimes restrict the output power under sinusoidal tone conditions as they do not have the thermal capacity or overload capacity to suck it up for a minute or so whilst the engineer measures it. In anticipation of this happening here I choose to make two measurement types. Continuous sinusoidal output for 1 minute (i.e. the traditional way) and output under 33% duty cycle conditions, which is a kind of burst rating but where the burst is repeated so as to deliver 33% maximum output. This is similar to saying that an amplifier must deliver 33% of its power indefinitely so that music signals with a low crest factor can still be reliably produced. 1/8th power is typical used for domestic equipment but 1/3rd seems safer for professional use where those dub bass lines can get quite demanding.


Speaking of bass, we also know that amplifiers cannot always deliver the same power at low frequencies as they do at 1KHz so I also measured both the conditions above at 31Hz and 1KHz. In order for the burst rating not to take a unfair advantage of the energy stored in the capacitors I chose the repetition rates for the burst to be relatively long so that the power output is what the power supply can sustain, not what it can do for 1ms!


So the 33% duty test signal used was as follows:
For the 1KHz measurement the signal is on for 70ms and off for 140ms.
For the 31Hz measurement the signal is on for 450ms and off for 900ms.

If the output power was kept below 1.7kW per channel then the amp would not trip. To leave a margin I left the amp running at 1.5kW per channel to see if I could get a 1 minute figure. Unfortunately after 15 seconds the circuit breaker opened, not surprising at it was drawing 22A from the mains at the time. So in the end I didn't get a 1 minute figure for 4 Ohms running but I expect it will be around the 1.2kW per channel mark as that produces a current draw of 15A which would eventually trip the breaker.


...

To summarise, for music signals, both channels driven, you can expect an output of:

Behringer:
1.37kW into 8 Ohms, 2.05kW into 4 Ohms for full-range or mid-top duty
1.16kW into 8 Ohms, 1.80kW into 4 Ohms for Bass duty"

That still doesn't jive with notynt's burst numbers. His CEA burst tones did not yield that level of power. The 6.5 cycles "burst" tone at 30Hz is only 217ms. That's less than half the 450ms signal teslaman used at 31Hz. Yes notynt measured only 1476W with a 217ms 30Hz tone burst. Teslaman measured 1.8kW using 450ms on, 900ms off (1/3rd duty) at 30Hz. However, teslaman is in the UK, so he's not testing with 120V into the amp like notynt. That probably explains the difference in power measurements.

You guys are assuming that:

NU4-6000=NU6000DPS

There is no reason that they have to be the same.

No, but if adding a DSP drops the power output of the amp by several hundred watts, something is very wrong.

They are different amps. Regardless of dsp or no dsp.

One is 4 channels and one is 2.

Same product line and manufacturer, but no reason they have to be the same.

iirc, not's test rig is 4.4 ohms, so that's half the difference right there. there may be some differences between the 6000's as well (2ch vs. 4ch).
