The EP4000 builds on the incredible legacy of our EP2500, which is one of the best-selling power amps in the industry. Our proprietary Accelerated Transient Response (ATR) Technology gives the EP4000 the massive power reserves needed for deep and impactful bass response, which translates into a more natural sound quality that will bring your audience to its feet – and keep them there! With an amazing 4,000-Watts of output power (2 x 2,000 Watts @ 2 Ohms; 2 x 1,400 Watts @ 4 Ohms; 4,000 Watts @ 4 Ohms in Bridge mode), the EP4000 is the perfect amplifier for medium-sized club gigs, mobile PA systems, church services or public spaces. • 2 x 2,000 Watts into 2 Ohms; 2 x 1,400 Watts into 4 Ohms; 4,000 Watts into 4 Ohms (bridge mode) • ATR (Accelerated Transient Response) technology for ultimate punch and clarity • Switchable limiters offer maximum output level with reliable overload protection • Detented gain controls for precise setting and matching of sensitivity • Precise Power, Signal and Clip LEDs to monitor performance • XLR and 1/4" TRS input connectors for compatibility with any source • Professional speaker connectors and "touch-proof" binding posts support most speaker wiring systems • Selectable low-frequency filters remove damaging infra-sound frequencies • Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers • High-current toroidal transformer for ultra-high transient response and absolute reliability • "Back-to-front" ventilation system including air filter for reliable operation • "Built-like-a-tank," impact-resistant, all-steel 2U rackmount chassis • Designed and engineered in Germany
