This item is no longer available.
When I'd help my friend's band set up for a gig, the last thing I wanted to see was a bunch of heavy amps mounted in a back-breaking amp rack. That's why Behringer's iNUKE pro audio amplifiers are such a welcome sight. These highly efficient yet lightweight amps deliver impressive power for any event. And, Behringer backs up their iNUKE amps with a 3-year warranty.
Weighing under seven pounds, Behringer's NU3000 2-channel amplifier pumps out 440 watts per channel at 8 ohms, 880 watts per channel at 4 ohms, and 1520 watts in bridged mode. Its class D design and "back to front" ventilation system ensure that it will run with virtually no thermal buildup, eliminating the need for the heavy transformers and massive heat sinks found in "old school" amps. This also means you can stack them close together in a rack. The built-in "Zero Attack" limiters let you get the most output, but still protect your speakers from being overdriven.
The NU3000 includes a built-in crossover, which can be set to full-range, low-pass for subwoofers, or high-pass for your satellite speakers. Front-panel illuminated controls provide precise level adjustments for each channel. The NU3000 also offers combination XLR and 1/4" input connectors for your source material and twist-lock output connections, compatible with Neutrik Speakon® connectors, for your speaker cables.

These amp has nuts!!
Excelente amplficador para mis dos JBL JRX 225
With more and more home theater setups using high power DIY subwoofers, the practice of using pro amps to drive them has become fairly common. The rating given above only pertains to the use of Behringer iNuke series amps in a home theater environment. The biggest drawback (and the reason I couldn't keep this amp) is the fan noise. Despite having been warned of the fan being unusually loud, I figured it wouldn't be any more audible than my HTPC and DVR. This was certainly not the case. Because of this, I cannot recommend iNuke series amps for any home theater application without a dedicated equipment room/closet. The undefeatable bright orange lights didn't help matters either. The other issue are the claimed power ratings. These amps are known for producing the most watts per dollar. It needs to be made specifically clear that the NU3000 produces 315 watts RMS per channel @ 8 ohms, 680 watts RMS per channel @ 4 ohms, and 1,040 watts RMS per channel @ 2 ohms. It is also worth noting that Behringer (as do several other pro amp manufacturers) does not follow the standard sine wave testing method to establish a specific power output at a certain frequency and distortion level. To be fair, some of the higher powered iNuke units do draw more current than a typical 15 or 20 amp outlet is able to provide for them to achieve their rated RMS power output; be sure to check the specs. I hope this helps someone make an informed decision prior to adding an iNuke to their home t
Pros: Great bang for your buck Very popular for live entertainment Hardly weighs anything for easier venue transport
Cons: Noisy fan Bright Lights Misleading power ratings
Used in my church to replace defective amp.Has excellent sound,no background noise-A+ amp.
This unit fits the rack and provides good power to the passive subwoofer. The controls are easy to set and the clip lights provide protection from too high volumes. This unit provided the wattage required with enough reserve to handle the speaker. The fan does make more noise than most equipment but it is not audible when any sounds are playing. This is the lowest price for the most wattage of all of the pro amps.
Pros: Low price Wattage provided
Cons: Fan noise Orange lights too bright No black finish

Overview: The Behringer iNuke NU3000 is a lightweight 2-channel amplifier delivers plenty of power when you need it. Featuring a "back-to-front" ventilation system, this Class-D amplifier runs cool with "near zero" thermal buildup. You can use the amplifier on stage connected to a mixer, or for DJ work. The NU3000 is rack-mountable, and requires 2U of rack space (no hardware included).
Built-in 3-way Crossover: The amp features a built-in 3-way crossover, which can be set to full-range, high-pass, or low-pass operation via a 3-way slide switch on the rear panel. Full-range mode sends an unfiltered output to the speakers. In HF mode, frequencies above 100Hz are sent to the speakers, while in LF mode, low-frequency content below 100Hz is sent to passive subwoofers.
Bridgeable: The NU3000's left and right channels can be bridged into a single output. The amplifier will produce 3000 watts when connected to a 4Ω speaker, or 1520 watts for an 8Ω speaker. A 3-way Mode switch on the rear panel lets you set the amp to Bridge mode, dual mono, or stereo mode.
Bi-amping: With two iNuke amplifiers (NU1000, NU3000, or NU6000), you can bi-amp a pair of speakers. Bi-amping splits an audio signal into lower and upper frequency bands, and sends each frequency band to separate speaker cabinets. Horizontal bi-amping uses one iNuke amplifier to amplify the low frequencies, while a separate iNuke amplifier handles the high frequencies. Vertical bi-amping uses a single amplifier for each stereo side. This requires an external crossover to separate the low frequencies from the mid/high frequencies so they can be amplified separately.
Connections: The iNuke NU3000 is equipped with two 1/4"-XLR combo inputs. The two outputs have professional twist-lock speaker connections that are compatible with Neutrik speakON connectors.
Front Panel Controls: The NU3000 features simple operation with detented rotary gain controls for channels A and B. Each control has three amber signal LEDs that light when signal is present, and a Clip LED to indicate when the signal is distorted and needs to be reduced. The gain control knobs feature amber and red illuminated rings that are easy to see in dark conditions.
Warranty Terms: Behringer offers a 3-year warranty when you register your product within 90 calendar days of purchase. If the product is not properly registered, the warranty period is one year.
