Behringer NX4-6000 Power Amp with Smart Sense

Behringer NX4-6000 Power Amp with Smart Sense offers a lightweight, rack-mountable and sturdy, stereo power amplifier capable of delivering 440W of peak power per channel at 8 Ohms, or in bridge mode, up to 1600W of peak power into two 8-Ohm speakers.  The Behringer NX4-6000 Power Amp packs an impressive amount of power into a lightweight, cool-running unit, that ensures you’ll have plenty of headroom to work with.  Employing SmartSense loudspeaker impedance compensation technology combined with a switch-mode power supply will enable you to benefit Benefit from a linear frequency response at any speaker load. Provide a linear 20 Hz to 20 kHz frequency response with noise-free audio and fast transient response at maximum output power, into any speaker load impedance. Zero-attack limiters supply maximum output with reliable overload protection. Experience low noise, superior transient response, and low power consumption, thanks to an efficient switch-mode power supply.

The NX4-6000 features cool-running, high-density Class-D technology with near-zero thermal buildup, and an independent DC, LF, and thermal overload protection on each channel, which together protect the amplifier from shutting down and interrupting your show. A variable-speed fan and ventilation openings with back-to-front air flow further prevent overheating.

Operating the NX4-6000 is dead simple. Benefit from at-a-glance confirmation of your system’s vital signs, by way of the NX4-6000’s simple front-panel controls and indicators. Positive-detent gain controls with signal level LEDs on each channel make gain staging a piece of cake. Rear-panel XLR combo input connectors ensure compatibility with just about any source. Reliable twist-lock speaker connectors prevent unwanted “unplugging” incidents. You also get switchable dual mono, stereo, and mono bridge modes, along with an easy-to-use stereo crossover.

There is no need for  massive heat sinks or toroid transformers any more, this D Class Power Amp from Behringer has an impressive amount of punch and clarity.
