Electro Voice CPS8.5-120V

The Dynacord CPS 4.10 is a high-efficiency, compact 4-channel amplifier, delivering 1000 watts per channel in a 1U rackmount design. Engineered for performance and reliability, it is ideal for professional audio installations and distributed systems requiring 70/100V operation. The Class-D topology ensures maximum energy efficiency and reduced heat output, while the amplifier supports flexible load configurations via IRIS-Net integration with an optional RCM-810 module.

Built with installation-friendly features, the CPS 4.10 includes Phoenix-type connections for streamlined cabling, remote power-on/off contacts, and programmable power-on delay. Comprehensive protection circuitry covers thermal, overload, short circuit, high-frequency, DC, back-EMF, and inrush current conditions, ensuring stable operation in demanding environments. Rear-mounted attenuators and a switchable 50 Hz high-pass filter in Hi-Z mode add further customization. Active front-to-rear cooling with variable-speed fans completes its robust build, making the CPS 4.10 a powerful and versatile solution for complex audio systems.
