I would only consider the 6000 inuke if there is a chance of adding more boxs because i would rather be amp limited for protection.

I have seen the 3000DSP for 330.00 online and I think for the 30$ more than retail non dsp, it is definitely worth the investment.

I'm in Canada and the closest place I can get one is Edmonton, AB. The nonDSP is 330 and the DSP is $420 or so.

Its a shame because across the line I've seen the ep4000 go for $280 new.

"RMS" watts is what you want to look at and with both channels driven it will probably be a little lower.

the dsp filters have a min setting of 20hz, but it is possible to wing it for a high pass down to at least 10hz. the dcx2496 has the same 20hz issue, but here is a way to overcome it:

http://www.avsforum.com/t/1461489/how-to-extend-the-high-pass-filter-below-20hz-in-dcx2496

not sure what the low end rolloff on these amps looks like.

^^ From the test here on the NU6000 it's 1.8 vs 2.05kW at 4R two or one channel driven respectively or 0.56dB difference.

i've never seen any of these amp tests use a load that is reflective of a true speaker. a large impedance spike in the middle of the bass is going to cut down dramatically on the current and should allow the amp to produce something closer to its full specified "watts" or perhaps even more.

i'm not thinking of this for those chasing 3hz where impedance dives to re, but more like the 20-80hz crowd. many drivers won't hit their re in that range and then with a typical 80hz low pass filter that cuts down power up there quite a bit.

i suppose my point is what an amp will do into 4 ohms of pure resistance is useful, but knowing how that translates into an actual speaker load might be even more revealing.

No it won't. The impedance spike of a typical speaker os an order of magnitude greater than Re. An amp is limited into high Z loads by it's effective rail voltage, ie, the voltage it can swing before it clips, so the Z peak is going to limit it to about what it can do into 8R. P=V^2/R

Sure, but the only device I know that could do it is a PowerCube and not many could afford one. Even if I had the $ I'd buy an AP first.

Audio Critic used one for the last couple of years to test amps.
post #156 of 182
I enjoyed reading the PowerCube pdf,.. interesting.

It would be so nice if there was one source of definitive and rigorous testing. Apples to Apples ... done.

I suspect many mfrs would relish the thought, similarly, many would run the other way, quickly.


Fortunately, the savvy enthusiast/working pro .... knows which design attributes helps an amp elicit robust characteristics in the parameters they're looking for.

My wife has a Klin-n-kut Element and it's Studio Software runs fine under VMware Fusion, including a USB dongle stick.
She uses it all the time, a 2D paper/material cutter.

Been trying for 45 minues to get the iNuke Remote Connect to recognize the iNuke, it does not.
I am able to get the iNuke hardware connected thru the USB bus, but the iNuke Remote Connect does not "see it".
Anybody else that uses MacOSX get this to work under VMware Fusion?
Picture shows the hardware is recognized.

Help - is my iNUKE NU3000DSP DOA?
Can't get my 2 subs to work under the iNUKE, they work fine under my EP2500.

Video shows what happens as the iNUKE powers up then goes into a shut-down mode??
Orange rings around the gain knobs go to red almost instantly.
I'm running in dual mode, with just a basic HPF @ 20HZto start with, saved as INIT_DAT1 which loads as default.
All other filters are off. This is 1st time I tried to use it since getting it a few months back.

fwiw, both my subs are SI, a 15" and 18" wired for 4ohm load.

I returned my iNUKE NU3000DSP to Amazon, they gave me a full refund.
They were out of the NU3000DSP....so I upgraded to the NU6000DSP, it just arrived tonight and I have it in my set-up.

Wow, is that fan loud! 68db at 12" from the front, definitely I am doing the fan mod this weekend.

I realize that at age 50 people say memory is the first thing to go, but back in 2008 when I got my EP2500 for my IB sub build before the fan mod it never was that loud.
Sure, it was an annoyance at low volumes but at higher volumes I never heard it, so I did that fan mod for low volume listening.

However, the iNuke sounds like a big ceiling fan on full blast, it's mandatory to do the fan mod if the amp is in your HT/Listening area at any volume listening.

Had to order a 2nd quiet fan, as the 6000 has 2 while the 3000 and 1000 has 1.
Same one from Amazon, came in yesterday.

http://www.amazon.com/gp/product/B000OVAM1W/ref=oh_details_o00_s01_i01?ie=UTF8&psc=1


Snip the wires, solder them and wrap in electrical tape, re-assemble just done this morning.

Dual quiet fans installed, I also removed the grab handles.....hated those things.....

Probably I have to do some EQs on DSP but I have to learn it how to use it. So; right now the 3000 DSP in Bridge mode performs pretty well on my 4ohm speaker. I have to sell the 3000 DSP Model as soon as I can get the 6000 DSP Model to power the two 4 ohm subs; currently I have one now and will buy another driver in the near future; or replace my 4 ohm driver and get a 2ohm driver with tighter response. Opinions please!

resurrecting this issue hoping the poster is around.

did you still hook the samson sconvert in the chain to get it work?

or, anyone here can chime in regarding the inuke3000dsp input sensitivity. does it really need a bump box to raise the input voltage to pro level? i am eyeing on this amp to be used together with an Onkyo 818 receiver for sub duties. appreciate a heads up if a samson or art cleanbox is really necessary.

I'm using this amp with an Onkyo 818. It's driving two LLT 18" subwoofers (1 4ohm driver per channel). In this scenario, gains are 1 notch passed 1/2 way, so the inputs are sensitive enough, or the 818 provides enough voltage from it's preamp.

Either way, it works very well with the Onkyo 818 without any signal boosters.

thanks for the speedy reply and glad hearing it from a user with first hand experience of the 818.

did you use an 2x RCA to XLR cable from the 2 sub out of the 818? how did you get away with the 20hz HPF to the LLTs?

It doesn't have RCA inputs, so you have to convert to Mono 1/4" TRS (Like what plugs into a guitar).

I used both rca outs into both inputs on the iNuke.

My version is the non-DSP version, so I didn't have to worry about any rumble filters. With this setup I have a flat response down to 10hz.

just for reference sake, what was the SUB out setting on the 818?

FWIW, (In case anyone with a Denon bumps into this thread in the future) I run the nu3000dsp off of the LFE out on a Denon 1909. I have the single rca output split with a Y adapter with two rca to unbalanced XLR cords connected to the 3000dsp.

The Denon can run the 3000dsp just fine with the gain knobs on the front of the 3000dsp cranked up.

During audyssey setup I told it that I have a subwoofer.

It then had me calibrate the subs to 75db. Since it has 2 sub outputs but they're both off the same signal, i unplugged one sub, dialed the other to 75db using the gain on the amp, then disconnected it and dialed in the other sub to 75db.

I then plugged them both in which showed a measurement of 78db. I hit next and did the calibrations.

After, it looked like audyssey attenuated the subs by -3db which makes sense.

I went in after and bumped up the speaker to sub crossover for all speakers to 80hz, and for most movies I run with the subwoofer level 3db hot.

thanks smile.gif

now, i would follow this procedure to calibrate 2 subs. i use to power both subs at the same time to reach 75db and bump it up later after the audyssey calibration

Snip the wires, solder them and wrap in electrical tape, re-assemble just done this morning.

I've probably replaced 100 or more PC power supply fans in the field.

This is the material of choice for splicing the wires:

http://www.amazon.com/Connector-Yellow-2-Wire-Splice-Pack/dp/B004EFK6LK/ref=sr_1_1



If no pliers for squishing them at hand, just bite it!

The silicon grease that squishes out is harmless, just spit it out.

Smaller packages at the big box home improvement stores.

A 3.3 ohm load in bridge mode will definitely send this amp into protect?

Never ever ever use a crappy scotch lok connector!! Use either a proper solder connection with heat shrink to seal it or at least use a crimp connection. Those crappy scotch lok connections are notorious for loose and partial connections.
post #175 of 182
Arnyk thx for tip on robust wire splicing fastener, I was not aware those so just did what I know works, old fashioned solder.

For field work where time=money definitely, and DIY work if you plan in advance then those are cats meow.

Did you reverse the fans? I. E. taking flow from front to rear................

Is it doable to reverse flow? Curious..............
post #177 of 182
not reccommended, as blowing directs the air much more than sucking (compare each on your shop vac)

I did reverse the fan on my EP4000.....and boy did it run way to HOT - temp wise.
So much I made a specific thread about it, EP2500 10 minutes no load-hot 180deg f (summary: do NOT reverse your fan direction)

Therefore, I will NEVER reverse a fan direction from what the engineers decided for any amp.

Guess I'm stuck with a Yamaha PS7000......
