These amps were from deton, still sold as SYNQ brand and others.

Interestingly I have recently owned some of the later production NU1000 and NU3000 models and they both have additional circuitry in them which is basically a UcD style class-D with feedback after the output filter! They still use the same MOSFET driver but have added a discrete comparator to drive it.
Seems they have been testing their new 'load invariant' designs in the field for some time now :) I suspect the different topology in the NU6000 means they didn't apply it to that model (as far as i know - I don't have any recently produced versions to check). The circuit also has an extra active LF pole over the standard UcD topology so should have very good damping factor at the low end. The only downside I have seen is a noticeable DC offset on the outputs caused by using a DC coupled circuit all the way from the DAC on the DSP models. This does lead to some rail pumping at idle on the worst one I've seen so I felt the need to fix it to improve reliability! Provided they solved this issue in the new range and keep the prices the same I think they will be good value again. If anyone has any late vintage NU6000s and can post a pic with the lid removed i can identify any newly added circuitry from that....

No harm commenting after you have seen in use! My pair are still going strong and certainly got the value I expected out of them. I bought the first one as a refurbished special and was what I could afford at the time. It did the job so I eventually picked up a 2nd one used to keep as a backup and for use on those rare occasions I rented a second pair of subs. I was running these on Yamaha CW218 cabinets so not the most extreme tests.
This year I built a pair of G-Subs loaded with RCF drivers and have found the INukes adequate for the heavier drivers. I now more frequently use both amps and have not had a breakdown to date.... I only use these things a half dozen times a year or so. Given my non pro and low utilization I am pleased with the purchase... if one dies during a gig I can at least keep 2 cabinets going. For what they cost these things met my expectations and I’m not sure the next alternatives are any more robust (Peavey IPR etc)x if the IPR series was anything like the amps they put on the first version of the powered ribbon monitors I’m glad I went with the cheaper Berry. Thanks for sharing your findings!

NX = New Xterior First thing ppl moaned about was the looks, not the sound but how it looked. So Berry have fixed the most important thing first I guess

Not one to resurrect an old thread but thought I would post on the thread that made me buy the inuke 6000DSP's in the first place!
Having used these now for around 4 years but never the same amp for longer than 2-3 years. I have always used them in pairs run dual mono mode with each side of the desk feeding each amp using a Y Splitter so i can control volume using the front knobs of each channel. Channel b is sub 40hz - 100hz and channel A 100hz upwards. They drive Martin audio S15+ and F10+ 8 ohm loads each channel. The bass cabs are run with the limiters not reduced so get about 1150w each, the tops have the limiter engaged to half power so they get around 500w per top cab. These get used 2 or 3 times a week and transported around quite a bit. Here is my view: - Amazing value, amazing DSP nothing comes close in this price range, very lightweight too which replaced Crown K2's i was using. - They have failed in different ways, the oldest one with a 2013 date code went bang a year or so back and blew out tracks on the board next to the output transistors. I replaced the output transistors with the exact substitutes as it was out of warranty patched the tracks it worked for a few months then happened again (worth a try) its now a parts amp. - The HF boost people talk about due to lack of output feedback is very apparent especially when you go to switch this amp out for something else after using it for so long and being used to how it sounds on tops. I think it totally depends on what HF driver you are using and its impedance curve at a given frequency. If the impedance is high the amps boost of HF will be high? The graphs from the test made on this thread do not show this in audible range but there is a definite boost after 6khz upwards to my ears which is very pronounced and exactly what you don't want when really pushing levels on mid-top boxes. One of the amps went down one night I switched to putting both tops creating a 4 Ohm load on the other , this sounded much much better but of course only mono so not ideal! - I also notice that running 2 subs from one side of the amp at 4 ohms seems to sound more 'solid' than running at 8 ohms on separate nu6000dsp amps with everything setup identical. if anything I would describe the sound difference as slight phase difference in the kick area band. What could cause this and what technical explanation could one give? It should sound slightly better since the power supply is loaded down less splitting the load of subs between amps? - No one should ever take just one of these amps to a gig they WILL fail it is only a matter of a time, 2 I have had fail on startup so the first thing I do is power them up then continue setting everything else up. The second most recent failure of one was sent back and the repair done was Diodes, this amp wouldn't start every time going into protect 95% of attempts to start it. - The latest failure on one less than a year old is more something I cannot pin point, the amp was on with no signal running and volume controls at zero it starts outputting what can be described as tv static/white noise through both channels at full volume (and I mean FULL volume) , as I rushed to switch the amp off I noticed that the screen for the DSP was off but the rest of the amp LED's were on (orange rings) It has not done this since but now leaves me worrying if its going to do it again when idling after setting up and I happen to be not there to switch it off burning out drivers in the process. Looking at the new NX range they may have fixed the HF issue (although boards look the same) but everything else looks like the same amp. For this reason I will be looking elsewhere for replacing them. I have always had a spare ready to swap when one fails but its clear that they fail too often and the white noise issue is just crazy and embarrassing so a deal breaker. You cannot expect too much at this price point but the crowns are in the garage and still work after 18 years! You definitely get what you pay for! I have a lot of other Birhringer kit so am not berry bashing but hope someone finds this helpful in deciding if they should go for one or the newer NX. |

inuke 6000 have 2x2000w/4ohm or 2x1200w/8ohm. your 18sound 21NLW9601 have big moving mass and you need power to move this cones. you need 4kw per driver if you want work without clip or to much heat in amp. Also amp damping factor on impedance must be 500 or more because more moving mass more speaker send load to amp.

Thanks bud, sure theres better amps for the job but like i said money is an issue atm, ill keep researching but take your comment into consideration, ill likely end up getting these, thank you |

Hi Chief--I think you would be fine running the NU6000 with your dual cabinets. Your subs can handle much more than my Yamaha clubs do, but I barely tick the amp at all when I run fairly large parties. I also know some folks that use these on their SRX's cabinets. I don't think you'd be displeased with the output you would get from these.
I have the DSP model and have a mode with the cross set at 90 hz and a limit setting on each channel. I've never tripped the breaker on the unit as noted in the original bench test as a potential issue in extreme cases. My application is almost always mid sized club venues doing house/techno, so I'm not as reliant on sustained bass as other types of EDM. |
