Nexo NXAMP4X4MK2 combines advanced signal processing with four state-of-the-art Class D amplifiers (4 x 4500w) to create a flexible, lightweight powering and control solution for NEXO loudspeaker systems.

Ideal for use in fixed installations and touring, these powered controllers are easy to set up and quick to deploy, with all essential parameters readily accessible via a large (4.3″) colour touch-screen on the front panel and a comprehensive range of control and networking facilities on the rear panel. Most importantly, NXAMPMK2 achieves a whole new level of sound quality, partnering with NEXO speakers to deliver a whole new level of audience experience.

4 x ultra-low distortion Class D amplifiers combine 32-bit/96KHz converters and 64-bit signal processing to deliver pristine sound quality. Bass is solid and high-end definition is particularly impressive in a sonic performance that is both articulate and rich with detail. Even at low volumes, the sound is noticeably transparent and pure.

A flexible audio input system encompasses four, high end analogue inputs using cascaded converters for low output noise. Four digital inputs are also available through the rear panel expansion card slot offering optional AES/EBU, EtherSound™, Dante™ or AES67 inputs, all with automatic analogue fall-back. A native dual Ethernet card facilitates remote control and daisy-chaining of amplifiers, and seamless integration with Nexo’s NeMo amplifier management software.
