Why is my Inuke shutting off

post #1 of 40
Thread Starter 
Anyone have any ideas why my Inuke 6000 keeps shutting off? It doesn't matter whether we are using it or not it will just shut down for a few seconds, then turn right back on.

I have my RX-A2000 wired to my balanced mini dsp, then to the Inuke 6000, then to the subs. I have done the fan mod and they appear to be working fine. Also, the mini dsp is still on default settings.

Any ideas?

Thanks

what ohm load do you have the subs wired to? what kind of subs are they?

4 OHM. I have 2 Dayton 18 HO's, each in their own sealed 21" cube.

how much power are you feeding? Where have you locked the peak limiter?

I guess full power, does the regular inuke have a limiter or is that just the dsp version?

I don't know if onew can limit the non-dsp model. Um not sure but I think your load protection circuitry is kicking in. I had the same problem with my 6000 DSP. do you manage to clip your inuke?

I think it is barely even getting a work out. The lights on the front hardly even blink at all

Are you running your cabs separately i.e. one on each channel of iNuke?

I just read you mentioned it shuts down even when not in use. Try hooking it in some other power socket and see if it shuts down again. Also, remove the input signal cables and output speaker cables, then simply start the amp. See if it again shuts down.

There are a couple of scenarios in which such a shutdown is encountered. Either it is thermal, some fault in the internal DC power supply, or trying to run lower impedence i.e. less than 4 ohms on NU6000. I don't think thermal shutdown and mismatched loads are the reasons in your case.

Also check if you are shorting speaker wires, that also triggers amplifiers protection circuitry. If your problem goes away by disconnecting the speakon plugs from inuke, then it most certainly is the wire shorting in the speakon connector.

You got a volt meter? See if it is getting low voltage 100v instead of 120v. That could be one reason. (or too HIGH.)
Either that or shorted speaker wires or too low of an ohmage; or the thing is just plain defective.

Alright guys it appears just switching wall sockets worked. I don't know why I didn't think of trying that.

I guess it's good to fell stupid every now and then. Better than it being defective.

Ok, it's been a few months and I am still having the same problem. I thought switching the plugs fixed it but it was just temporary. It kind of makes me think it is getting too hot. When I first turn it on it works fine for about 20-30 minutes then starts shutting off again and begins to do so quite frequently. If I let it take a break and cool down it will work for a longer period of time once again. I have switched fans a couple of times and used fans that others have had success with, yet the issue still persists. I have also just ran it with the top off and it still shuts down so I am ow out of ideas. I would just return the thing but I am guessing that the fan Mod automatically voided my warranty.

Any ideas?

I don't know if it matters but the mini dsp is no longer in the mix. It runs straight from the unbalanced RCA plugs on the RX-A2000 to the balanced plugs on the inuke, then goes from the neutrik outputs to a splice raw wire into the subwoofers.

You say you switched fans... Have you tried the stock fan?

does it have good air flow around it ? i would just stick the old fans in it and send it back.

I no longer have the stock fans. It definitely has good airflow around it as I have pulled it out into the middle of the floor, took its top off and it still continues to shut off.
post #18 of 40

Do you have a box fan or something that you can direct airflow directly inside the case?

u didnt remove the shroud that directs air flow did u ?

I added heatsinks to the inside of mine with thermal glue... if you look up vga heat sinks you can find them fleabay for very cheap....

My 6000DSP would shut down constantly even when idling without decent airflow from the fans. I really wanted the new fans to work, as they were dead silentt, but it simply was not enough cooling and it would go into protect mode if the ambient temp in the room was high enough (= nearly instant shut down), or the amp was turned on long enough.

I swapped those fans out for some that were slightly more powerful and it made all the difference. I can hear them slightly, but it never shuts off even if I'm hammering it (pair or lms-r 15's).

Try new fans and see how that works.

There is no shroud on the 6k, just the 1k and 3k.

I had the exact same experience as you. Tried 3 sets of fans, finally, the third set did the trick. Even though it never felt warm, it could shut down about every 5 minutes for a couple seconds. I used the spreadsheet on Digikey.com to look for the original fans, then came down 10dB to the ones that worked. Don't leave the cover off - that disrupts the flow through the case. I admit - the stock fans even behind a cabinet door are WAY to loud for home use! I think the 3000 is much less prone to heat than the 6000DSP I have.

Thanks for these posts...smile.gif

I tried a Lepa 70D08R cooling case fan based on a recommendation from another inuke thread but the 6000 would start to shut down after 20 minutes. I had a Kill-a-Watt meter on it and it showed a 50 watt draw and was cool to the touch. I am going with sbdman's advice and ordered two new fans from Digikey that dropped 10dB and 900 RPM and keeps the CFM at just under the stock fans...I don't need it to be dead quiet. I will see how this works and report back.

I was on my 3rd fan and it was still shutting off. I was about to just give up, when i just happen to be on the LG clone amp thread and read that someone had switched the direction their fan was blowing and it helped them. So, I decided to give it a try. My fans were blowing from back to front so I switched them to blowing front to back and they never shut off again.

Thanks ozziedog...I will keep this in mind if the next set of fans don't work.

No problem, I hope you get it working. It has been a hell of an amp since it quit shutting off.
post #27 of 40
The second set of fans arrived today from Digi-key. I used their search function to find the specs on the stock fan from my 6000:

4000 rpm
3.86 watts
40 dB
.290 amp
45.9 cfm

I ordered the P14749-ND to replace it:

3100 rpm
1.86 watts
30 dB
.140 amp
41.3 cfm

I am reading 38dBA at one foot which is okay for this set-up and it has been running for several hours without shutting down...it is in the noise floor at this point. smile.gif

Awesome, I hope this fixes it for you. It is a good amp when working!

Out of curiosity what direction is everyone's fan blowing on your inukes? I want to know if mine were installed incorrectly or if just got lucky.

Hey ozziedog, I have owned (4) EP-4000 amps and the inuke 6000 and all of the fans draw in air from behind the unit and exhaust it through the front of the unit...
