A Flexible Amplifier for All Live Sound Applications

When we're designing live sound systems at Sweetwater, we work to ensure every piece of gear in your system is as efficient as possible. We were impressed with the Behringer iNuke NU4-6000 power amplifier because it packs four powerful channels of amplification into a compact, flexible design. You can power two mains at 1,500 watts each while powering your subwoofer in bridged-mono mode at 3,000 watts. Or power your mains and run two separate monitor mixes through it. However you use it, the Behringer iNuke NU4-6000 gives you a lot of power in a single, compact amplifier.

The latest in power amp technology

Power amp technology is constantly evolving, and the Behringer iNuke NU4-6000 power amp takes advantage of the latest advancements. Thanks to the revolutionary Class-D technology with "near-zero" thermal buildup, the lightweight iNuke NU4-6000 runs cool without the need for massive heat sinks or toroid transformers. A built-in limiter offers overload protection to extend the life of your precious speakers and subs.

3-way crossover cleans up systems with mains & subs

On the back of the iNuke NU4-6000 power amp you'll find a pair of 3-way crossover switches. In center position is Full Range mode, which sends the full power of your channels, unfiltered, to your loudspeakers. This is what you'll want if you're dedicating your amp only to your full-range mains and monitors. But if you're running a mixed system with both mains and subs, the two other positions create a powerful and well-defined sound fast without additional processors. LF mode on the left sends only low-frequency content below 100 Hz to your subs; HF mode on the right sends only content above 100Hz to your full-range loudspeakers.

A flexible amp for many different applications

The iNuke NU4-6000 power amp sports four powerful channels, and you have a lot of options for how you use them. You can run all four channels independently at 1,500 watts each, perfect for delivering four separate monitor mixes to the stage. Or power your mains with two channels, then bridge the other two for maximum power to your subwoofer. No matter what your system consists of, the iNuke NU4-6000 is ready to integrate with it.

Behringer iNuke NU4-6000 4-channel Power Amplifier Features:

  • Four-channel Class D power amp delivers 4 x 1,500W (2 ohms) or 2 x 3,000W (4 ohms)
  • Built-in 3-way crossovers make it easy to combine main speakers with subwoofers
  • Detented, illuminated gain controls allow for precise level setting
  • Switch-mode power supply provides noise-free audio and exceptional transient response
  • Built-in limiters provide reliable overload protection to protect your speakers
  • 3-year manufacturer warranty

I'm getting more of these

Used the for a five day fair 14 hours a day for my double 18s. Worked flawlessly and sounded great through a driverack. 3 easy payments and it was mine. Will get more of these to replace my 55 lb peavey amps.

Game Changer

I got this amp because I wanted the ability to feed my four EV floor monitors separate mixes without having to carry an extra heavy amp. I replaced a brand name 28lb, 2 space, 2 channel amp with this Behringer NU4-6000 12lb, 2 space, 4 channel amp. I was a little skeptical that a 12lb amp could really deliver 4 x 440watts @ 8 ohms but I took the chance. This Class "D" technology really works as advertised. I've used the amp for hours in live gigs and the amp runs cool. Since heat is what usually damages electronic components, it should last a long time. I put the amp in a good case to protect it from road damage. The amp is musical and clean. I really can't hear any difference between this amp and a traditional class AB amp. This amp is rated at 4 x 440 watts @ 8 ohms and from what I can tell, it is just as powerful as the 2 channel 500 watt amp it replaced, and it weighs less than half as much! Every once in a while something comes along that is a game changer. These amps are game changers and are a great watt per dollar value.

I own 4 iNuke 6000s Which I use in my band and rental systems and I am very happy with them they can take whatever you throw at them and are very light and economical, when I saw the iNuke nu4-6000 I thought this is ideal for monitors I used them on a gig on an outside gig on Saturday to power 4 monitors they worked pretty good and on sunday in medium club I used it on bi amp mode for main reinforcement I was sold

Swiss army knife amp

I moved away from Behringer products a few years ago, but this amp intrigued me. A 4 channel, 12 Lb amp? My G/F is a tech and I was trying to lighten her load in/out. I bought two and rigged one for 4 monitor mixes and the other for a small tri-amp PA in one 30 Lb rack. Everything you need for a club, low wall power draw, light weight, and efficient enough to do the job. Oh, and inexpensive too. I have since bought a third for monitors (4 mixes) for another rig. I will be buying a fourth for the same application.
