Electro-Voice's new Precision Series Compact amplifiers offer proven Precision Series performance and reliability in a new 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 CP1800 supplies up to 2 x 900 watts into 2 ohms and 2 x 600 watts into 4 ohms. Dedicated for smaller full-range speaker systems and hi-frequency components in multiway systems. The CP1800 uses a conventional transformer power supply.
