The CPS1 from Electro-Voice is a rack mountable power amplifier ideal for installed and contractor applications. Capable of operating in dual, parallel, or bridge-mono modes, the amplifier provides plenty of power to meet your needs.
The unit features balanced XLR inputs with parallel Phoenix-type inputs for versatility. Outputs are on standard screw terminal connectors. A ground-lift switch is provided near the connectors to help reduce hum caused by ground loops.
To keep your system running smoothly, numerous protection features are built-in. Dual cooling fans run silently and have three levels of intensity. Protection circuitry for thermal overload, short circuits, and DC is included, and during start-up the output connection is delayed to avoid blowing the mains fuse.
The system's level control is found on the rear panel, and front-panel LEDs display power, protect, signal, and limit status for both channels. For powerful sound and terrific reliability at an affordable price, the CPS1 is a great option.
