Key Features 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 for maximum output with reliable overload protection Detented gain controls for precise sensitivity matching Power, Signal, and Clip LEDs for performance monitoring XLR and 1/4" TRS input connectors for versatile source compatibility Professional speaker connectors and touch-proof binding posts Selectable low-frequency filters to remove damaging infra-sound frequencies Independent DC and thermal overload protection on each channel High-current toroidal transformer for ultra-high transient response and reliability Back-to-front ventilation system with air filter for dependable operation Impact-resistant, all-steel 2U rackmount chassis for roadworthy durability Designed and engineered by BEHRINGER Germany Overview The Behringer EP4000 stereo power amplifier combines exceptional sound quality with rugged construction and low-noise operation. With 4,000 Watts of power, it is perfect for medium-sized club gigs, mobile PA systems, church services, and public spaces. Advanced Controls and Protection The front panel features simple controls with independent gain dials for each channel, along with Power, Signal, and Clip LEDs to monitor performance and prevent distortion. The rear panel offers switchable clip limiters that automatically reduce input levels to avoid clipping distortion, ensuring clean sound output. Low Cut Filters remove unwanted ultra-low frequencies (below 30 Hz or 50 Hz) to protect speakers and improve bass clarity. The amplifier can be configured in Stereo, Bridge (mono), or Parallel mode for flexible system integration. Robust Build and Reliable Components Inside, the EP4000 uses reliable Toshiba/Fairchild power transistors and a high-current toroidal transformer for superior transient response. Independent DC and thermal overload protection safeguards both the amplifier and connected speakers. Inputs include XLR and 1/4" TRS connectors, while outputs support Speakon-compatible connectors and 5-way binding posts, accommodating various speaker wiring setups. The back-to-front cooling system with an exhaust fan and air filter ensures stable operation during extended use. Accelerated Transient Response (ATR) Technology ATR technology enables the amplifier to deliver fast, powerful pulses of current and voltage, resulting in tighter, crisper bass and a more natural sound. This makes the EP4000 ideal for demanding audio applications where clarity and punch are essential. Legacy of Performance The EP4000 builds on the success of the EP1500 and EP2500 models, offering professional-grade performance and durability at an affordable price. Choose the EP4000 for reliable, high-powered amplification that won’t break the bank.
