This dedicated Class D amplifier with high efficiency, cool running and low standby voltage consumption is a further development of the amplifiers built into the popular M&K Sound V Series subwoofers. The Class D switch mode power module is designed with effective power reserves to effortlessly deliver copious amounts of clean power to the IW28S In-Wall sub for extraordinary, uncompromising handling of demanding deep bass transients. A precisely calibrated dynamic headroom control circuit constantly monitors the signal to prevent audio clipping, while maintaining the full dynamic range of modern digital audio formats. Stereo inputs and line-level pass-through connections provide valuable flexibility for system building and future expansion.

For perfect sonic integration with any satellite system, VA500 incorporates adjustable gain control including a fixed level position for reference setup, continuously variable phase (0-180 degrees), variable crossover frequency (60Hz - 200Hz) and three-position room adaptation. The amp is one standard rack unit high and is supplied with removable handles for mounting in a 19” pro rack and feet for stand-alone placement.
