The Electro-Voice CP4000S is a 2-channel, 2U rack-mount power amplifier designed for the rigors of live touring, offering high efficiency and great quality sound. Three user-selectable performance modes are available - dual, parallel, and bridged. The amplifier features XLR input connectors and XLR and Speakon output connectors for connection to any professional sound system.
The CP4000S uses an optimized power supply with low-leakage toroidal transformers for outstanding audio performance with extensive headroom. Internal circuitry minimizes potential damage from electrical and thermal overload, short circuits, and HF/DC at the outputs. Other protection measures include back-EMF-protection, which prevents damage to the output resistors by electrical back-feed, an inrush current limiter, delayed connection of the outputs at power-up, and dual three-speed fans.
