Behringer EP4000 4000W Stereo Power Amplifier with ATR (Accelerated Transient Response) Technology

Behringer EP4000 4000W Stereo Power Amplifier with ATR (Accelerated Transient Response) Technology

Behringer EP4000 is a professional stereo power amplifier designed for high-power sound reinforcement systems and installed audio applications. It provides reliable amplification for passive loudspeakers in venues, touring rigs, and professional PA systems where consistent high-output performance is required.

The amplifier operates using ATR Accelerated Transient Response technology combined with a high-current toroidal transformer to deliver fast transient response and powerful output. Integrated protection circuits monitor thermal conditions, DC faults, and signal levels to protect both the amplifier and connected loudspeakers.

This architecture allows sound engineers to drive demanding speaker systems with stable high-output power and reliable monitoring feedback. It supports flexible input and speaker connectivity options compatible with professional audio equipment.

Key Features

• High Power Output: Delivers up to 2 × 2,000 W into 2 Ω and 2 × 1,400 W into 4 Ω for demanding PA systems.
• Bridge Mode Capability: Provides up to 4,000 W into 4 Ω when configured in bridge mode.
• ATR Technology: Accelerated Transient Response improves punch and dynamic clarity.
• Switchable Limiters: Built-in limiters allow maximum output levels while preventing overload.
• Detented Gain Controls: Precisely adjustable controls allow accurate sensitivity matching.
• Status Indicators: Power, Signal, and Clip LEDs provide real-time monitoring.
• Flexible Connectivity: XLR and 1/4" TRS inputs accept signals from professional audio sources.
• Multiple Speaker Outputs: Professional speaker connectors and touch-proof binding posts support various wiring systems.
• Protection Circuits: Independent DC and thermal protection automatically safeguard the amplifier and speakers.
• Tour-Ready Construction: Rugged all-steel 2U rackmount chassis designed for professional environments.
