Behringer NX4-6000 Portable Power Amplifier Overview:NX4-6000The NX4-6000 power amplifier packs 6000 Watts (4 x 1600 Watts @ 2 Ohms; 2 x 3000 Watts @ 4 Ohms) into exceptionally lightweight (13.4 lbs / 6.1 kg) and rack-mountable packages. And because the NX4-6000 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 that offer maximum output level with exceptionally-reliable overload protection and SmartSense Loudspeaker impedance compensation, which provides fully linear frequency response at any speaker load impedance, you can run the NX4-6000 full-out for hours on-end. Our revolutionary high-density Class-D technology, combined with an ultra-efficient, switch-mode power supply ensure this feather-light powerhouse will drive your rig effortlessly for many years to come.Class-D – Massive Power, Perfect SoundThanks to our High-Density 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 OperationThe 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 Limit LEDs to indicate when the amplifier is running at full capacity. Just as elegant as the front, the rear panel is home to the combo XLR and 
1/4″ TRS Input connectors, making the NX4-6000 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 NX4-6000 amp to run in your choice of dual mono, stereo or mono bridge modes. The NX4-6000’s built-in Crossover switch sets the amp to Full-Range mode, where the output is sent unfiltered to your loudspeakers, or Bi-amp mode, which sends only the low-frequency content (<100 Hz) to passive subwoofers, while the high-frequency content (>100 Hz) is channeled to your full-range loudspeakers.SmartSense Impedance CompensationSmartSense Technology puts the punch back into Class-D amplification, providing vastly improved full-range frequency response with more powerfully-dynamic bass, and smoother high-frequency reproduction. The resulting output is no longer dependent on the actual load, but is rendered perfectly ruler flat via impedance compensation. NX4-6000’s design also incorporates a significantly-higher damping factor that yields better amplifier control over the loudspeaker for stronger audio reproduction – especially in the LF area.Sound ValueSporting massive output ratings, lightweight Class-D technology and an equally lightweight price tag – plus all the amenities a professional audio engineer could ask for – the BEHRINGER NX4-6000 power amplifier is a serious amp for your most demanding applications.Features:
