How Many Amps Does Behringer Inuke Nu3000 Draw

bolserst · 2013-10-12 12:31 am

I am posting some measurement information on the NU3000 that might be of use to those considering the purchase.

Output Power:
No load max output voltage was 50Vrms per channel.

With resistive loads, power output at clipping was pretty darn shut to:
300Wrms/8ohm/aqueduct
600Wrms/4ohm/aqueduct
1000Wrms/2ohm/channel
2000Wrms/4ohm/bridged

So, it seems yous can pretty much take the Behringer specs and divide the ability ratings by sqrt(2).

It has been brought to my attention that Behringer does provide RMS Power ratings in a brochure, only not in the manual.
They line up well with measurements summarized in a higher place. See postal service#11 below:

It seems that Behringer has removed the link from mail service#eleven containing the brochure with RMS ratings for the NU1000/3000/6000. Every bit far as I could tell, none of the newer brochures comprise RMS ratings. So...I attached an excerpt from the older brochure containing this information in mail#29

Frequency Response:
Zipper #1: Resistive load test
Attachment #two: Capacitive load test
Attachment #3: Inductive load test
Attachment #4: ESL load examination

In Summary:
- For the money this amp puts out plenty of power, but load induced HF response changes indicate information technology is probably best used for subwoofer duty.
- The DSP is pretty slick. In item, very handy to be able to dial in limiter setting in real time to keep woofer circuit beneath the clatter zone.
- Not recommended for driving ESLs.

Thank you for the info. I was satisfied enough to purchase two

While discussed at length in other threads hither, I "modded" mine to silent operation past no fan/no cover. So far no problems. Based on my express tests, I can go peradventure 14 w/Ch (continuous) into 4 ohms speaker before the thermal protection shuts downwards a channel. Of course with the far higher acme voltages this amp can exercise LOUD. Even with the no fan limitation, a NU3000 puts out enough of power to drive iv Bose 901 (series II) loud enough to annoy the girlfriend and the neighbors :cuss:

How-do-you-do raintalk,

Thanks for the link!
Prissy to see RMS Power specs line upwardly nicely with my measurements.

I had not seen RMS power ratings for the iNukes published anywhere.
The transmission only lists "Maximum" as does all the seller websites like Parts Express.
Estimate I didn't await hard enough...

I'm using the Inuke 6000 dsp to power 2 b-52 220s subs, rated for thousand watts a peace. im going to be getting 2 more and my plan was to run all iv on my inuke. but since ive seen that my subs desire more power than what the inuke can give them, i desire to endeavour bridging it, build a box that would accept both speakon lines in, bridge both positive and negative lines from both channels together, and and then run them out to 2 subs at a 4 ohm load off both channels. that would technically depict all the ability off the amp right?
would this exist prophylactic? would it blow my amp? if there was any problem i would think information technology would go into protection mode start, i would attempt it at low levels commencement of course.

i dont belive that my amp puts out a true 6000 watts, i agree that it probly puts out well-nigh 4000w, its two bridged 3000's in ane box.
