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. Applications Professional audio engineering and music production Live sound reinforcement and concerts Sound systems in clubs, concert halls, and public venues Mobile DJs and corporate events Fixed installations in restaurants, bars, and commercial spaces Recording and rehearsal studios Detailed Technical Specifications Total Power: 6000W Power at 2 Ω: 4 × 1600W Power at 4 Ω (bridged mode): 2 × 3000W Amplifier Type: Class-D (high-efficiency technology) Input Connectors: Combo XLR and 1/4" TRS Speaker Connectors: Professional twist-lock sockets Bi-amp crossover frequency: 100 Hz Weight: 6.1 kg Materials and Construction The amplifier features a robust, professional 2U rack construction with a front-to-rear ventilation system that effectively prevents heat buildup and ensures reliable operation even during long sessions. Precision locking gain knobs allow for accurate signal level setting, and 4-segment LED indicators (signal and limiter) enable real-time monitoring of each channel's performance. Independent protection against DC current, low frequencies (LF), and overheating on each channel automatically safeguards the amplifier and speakers without interrupting the show.
