Monolith Two-Channel Stereo Power Amplifier - Black with 2x200 Watt Per Channel, XLR Inputs, for Home Theater & Studio

Power: A true 200-watt experience. Unlike most amplifiers or receivers, the Monolith's 200 watts per channel rating is measured with all seven channels driven across the full power bandwidth of 20Hz to 20kHz into 8-ohm loads.
Additionally, there is NO current limiting and there is no protection circuitry in the amplifier circuit path. Even if the speakers' impedance drops to a low level, the Monolith is robust enough that the current is never limited.
Dynamics: High resolution audio delivers the best in music and movie soundtracks. You deserve an amplifier capable of delivering clear and clean audio across a wide dynamic range!
With a more than 120dB signal to noise ratio, the Monolith 2 can clearly and accurately articulate the quietest portions, the loudest portions, and everything in between.
Class AB: More efficient than Class A, many high end, audiophile grade amplifiers utilize a Class AB design.
