Overview

The Behringer KM1700 is a two-channel stereo power amplifier engineered for professional live sound, installed audio, and monitoring applications. It produces 2 × 800 watts into 4-ohm loads in stereo, 2 × 500 watts into 8 ohms, or a full 1700 watts into 8 ohms when bridged to mono — providing enough headroom to drive passive loudspeakers in mid-sized venues, houses of worship, and performance spaces. At the core of its design is Behringer's Accelerated Transient Response (ATR) technology, which optimizes the amplifier's ability to track and reproduce fast-moving signal transients, resulting in tighter low-frequency control and more articulate high-frequency detail.

The rear panel offers both XLR and quarter-inch TRS balanced inputs on each channel, ensuring seamless integration with mixing consoles, signal processors, and other professional audio sources. Switchable limiters on each channel provide reliable overload protection for connected speakers, while front-panel LEDs for power, signal, and clip give operators immediate visual feedback on the amplifier's status. The steel chassis and standard rack-mount form factor make it well-suited for permanent rack installations, and the internal cooling system keeps operating temperatures in check during extended high-output use.
