Behringer iNUKE NU12000 Ultra-Lightweight, High-Density 12000-Watt Power Amplifier

Product Highlights

The iNUKE NU12000 power amplifiers packs an incredible 12,000 Watts (2 x 6,000 Watts @ 2 Ohms; 2 x 3,400 Watts @ 4 Ohms; 2 x 1,700 Watts @ 8 Ohms) into exceptionally lightweight (26.5 lbs/12 kg) and rack-mountable packages. And because the NU12000 is so much more efficient than conventional designs, it runs cooler and doesn’t require the massive heat sinks and heavy toroid transformers typically associated with its conventional counterparts. Thanks to our “Zero- Attack” limiters, which offer maximum output level with exceptionally- reliable overload protection, you can run the NU12000 full-out for hours on-end. Our revolutionary high-density Class-D technology, combined with ultra-efficient, switch-mode power supplies, ensures this feather-light powerhouse will drive your rig effortlessly for many years to come.

Class-D - Massive Power, Perfect Sound

Thanks to our revolutionary Class-D amplifier technology, we are able to provide you with enormous power and incredible sonic performance in an easy-to-use, ultra-portable and lightweight package. Class-D amplification makes all the difference, offering the ultimate in energy efficiency – and eliminating the need for heavy power supplies and massive heat sinks. This amazing technology makes it possible to design and build extremely-powerful products that are significantly lighter in weight than their traditional counterparts, while using less energy and protecting the environment.

Sublimely Simple Operation

The front panel controls and indicators provide your system’s vital signs at a glance. After pressing the Power button, the Power LED lights to show the amp is ready for action. All channels feature positive-detent Gain controls with Signal LEDs that light when a signal is present, as well as Clip LEDs to indicate when the signal is distorted and you need to reduce the input signal.

Just as elegant as the front, the rear panel is home to the combo XLR and 1?4" TRS Input connectors, making the iNUKE compatible with virtually any source, balanced or unbalanced. Professional twist- lock speaker sockets are provided to ensure every drop of output power gets to your loudspeakers. The rear panel is also where you’ll find the switches that enable the NU12000 amp to run in your choice of dual mono, stereo or mono bridge modes.

Three Ways to Shape Your Sound

The NU12000 features a built-in 3-way Crossover, which is selectable as: Full-Range mode, where the output is sent unfiltered to your loudspeakers; LF mode, which sends the low-frequency content (<100 Hz) to passive subwoofers, or HF mode, where the high-frequency content (>100 Hz) is channeled to your full-range loudspeakers.

Sound Value

Sporting massive output ratings, lightweight Class-D technology, an equally lightweight price tag – and all the amenities a professional audio engineer could ask for – the iNUKE NU12000 power amplifier is a serious amp for your most demanding applications.
