The NX4-6000 power amplifier packs 6000W (4 x 1600W at 2 Ohms, 2 x 3000W at 4 Ohms) into exceptionally lightweight (13.4lbs/6.1kg) and rack-mountable packages. 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. “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.
