The Electro-Voice CP1800 is a highly efficient 2-channel Class-H power amplifier belonging to EV’s Precision Series Compact line. It packs high-power delivery and standard touring reliability into a standard 2U rack space format weighing around 15 kg (33 lbs).
Unlike your previous modern switch-mode amplifier query, the CP1800 relies on a rugged, conventional low-leakage toroidal transformer power supply combined with a multi-stage Class-H topology to reduce operational heat and chassis footprint.
