Behringer NX4-6000 — 6000W Class-D Power Amplifier

The Behringer NX4-6000 is a revolutionary four-channel power amplifier that delivers an impressive 6000W of power in an exceptionally lightweight and compact rack enclosure. This ultra-light design, weighing only 6.1 kg, redefines the standards for professional audio amplifiers by combining massive output power with extraordinary portability. Thanks to advanced high-efficiency Class-D technology, the NX4-6000 operates significantly more efficiently than traditional amplifiers, eliminating the need for bulky heat sinks and heavy toroidal transformers.

Product Features

The amplifier offers 4 × 1600W at 2 Ω or 2 × 3000W in bridged mono mode at 4 Ω, making it the ideal solution for driving even the most demanding speaker systems. SmartSense Loudspeaker Impedance Compensation technology ensures a fully linear frequency response at any speaker load impedance, guaranteeing optimal sound quality regardless of the system configuration. The Zero-Attack Limiter provides maximum output level with exceptionally reliable overload protection, safeguarding both the amplifier and connected speakers.

Professional Capabilities for Demanding Applications

The NX4-6000 is designed with the most demanding professional applications in mind. The ultra-efficient switching-mode power supply (SMPS) ensures a quiet audio path, excellent transient response, and minimal energy consumption, while simultaneously eliminating unnecessary heat generation during operation. The built-in crossover switch with Full-Range or Bi-amp (100 Hz) modes enables flexible system configuration, ideal for both full-range speaker systems and advanced setups with subwoofers. Dual mono, stereo, or mono bridge operating modes provide maximum versatility when integrating with existing audio systems.
