Title: Behringer NU4-6000 Amplifer
Post by: Al Rettich on May 07, 2018, 09:25:36 pm
Anyone have one of these? Looking to use this to power some outdoor speakers. Problem is each one of these speakers is 8ohms at 600w, not seeing anything from behringer about it being able to run at 8 ohms.

Quote from a Behringer rep reply on their forum.

4x 440Watt @ 8 Ohm Maximum Output Power is correct. To go more into detail about the NU4-6000, it has two separate NU3000 units within and both of these amplifiers can be used completely independent. For an example, you can have one set of outputs in Bridge mode and one set to Stereo mode. This also means that you can run separate ohm loads on each channel as well because they are individual. 

If you set channels A & B into Bridge mode then you will use Terminal A, or terminal C if you set outputs C & D into Bridge mode.

The actual power output is around 300/600/1000w into 8/4/2ohm.

For a pair of 600w (continuous) cabs, I'd bridge it down to two channels and put one on each. That'll give you around 1200w per box.
If you didn't bother bridging, you'd have 6dB less headroom, which might not be the end of the world. The speakers would have an easier time.

I HAve 3 of the May.  THEY work great and versatile AF.  Donít t let them clip and youíre gold.  Surprisingly reliable, and cheap enough to carry a backup at all times.

I'm with Dave.

I have 2, and some NU-6000dsp.

Great bang for your buck. Dependable. Light. Run cool. Sound good.

My only complaint about the iNuke series is the fact that the Nu6000 DSP in my friend's club exhibits a profound power off pop if mains power is disconnected when the amp's power switch is in the on position.  All the other models I have used and tested do not do this.  A quick search seems to suggest that this issue is unique to the 6000DSP model.  YMMV.

How is the noise floor on the DSP version? I heard when they first came out that the DSP version was a lot noisier than the non-DSP ones, so I only have the latter. Out of about 20 amps of the NU4's, I've only had one die. We were using it at a gig and it just quit. One channel in use, one monitor connected, not very loud. Plugged in spare and all was good.

They sound great, are very light, and are otherwise reliable IME.

If the OP needs only 2 channels of more power than 300 watts, just get the 2 channel one. It's got the same guts as the 4 channel but has the two pairs of internal channels permanently bridged. It's a little cheaper than the 4 channel one, IIRC.

Honestly, I have not noticed any difference in the noise floor on the 6000dsp on mains versus the 3000 I have on monitors. but I admit to not having done any critical listening with that in mind.

here is a good read on the 2 channel behringer.
