The Behringer KM400 professional 400-watt stereo power amplifier is designed to deliver exceptional audio performance with precision and reliability. Built for live sound, studio applications, or installation use, it combines robust construction with advanced audio technology.
Featuring Behringer's ATR (Accelerated Transient Response) technology, the KM400 provides ultimate punch and clarity, ensuring your sound remains crisp and dynamic even at high output levels. With versatile power handling, it delivers 2 x 190 watts into 4 ohms, 2 x 120 watts into 8 ohms, or 400 watts in bridge mode at 8 ohms, offering flexibility for a wide range of speaker setups. Its “zero-attack” limiters protect your equipment while allowing maximum output, and precise signal and clip LEDs provide instant visual feedback.
Equipped with professional XLR inputs for balanced signals and twist-lock speaker connectors for secure operation, the KM400 is designed to maintain clean, noise-free audio. Its ultra-efficient switch-mode power supply and front-to-back ventilation guarantee superior transient response and reliable operation, while its rugged all-steel 2U rackmount chassis ensures it can withstand the rigours of professional use.
