Electro-Voice’s Precision Series Compact amplifiers offer proven Precision Series performance and reliability in a  compact, lightweight format. This is made possible by incorporating a highly efficient Class-H design, which results in considerably less heat being generated. This allows the overall size of the amplifier to be reduced substantially without sacrificing performance or reliability. The CP3000S is not only the first Precision Series amplifier to use a switch-mode power supply, but also the first switch-mode amplifier with EV’s Precision Series sound. With up to 2 x 1600 watts into 2 ohms and 2 x 1100 watts into 4 ohms, it is both powerful and lightweight, at only 17.96 lbs (8.15 kg). The CP3000S is state-of-the-art for all kinds of applications. It is specifically designed to allow for long-term driving of low loads into subwoofers without stress. The CP3000S's reliability and its pleasing, rich sound make it the first choice for all mid- and hi-range speaker cabinets.
