About Electro-Voice CPS4.5

The Electro-Voice CPS4.5 4x 500W Power Amplifier is offers four independent Class-D Variable Load Drive (VLD) amplifier blocks, each one capable of delivering up to 500 Watts into Low-Z or High-Z loads. Per default, each channel can be configured individually for max. power output into either 2 Ohms , 4 Ohms , 70V- or 100Vnetworks without involvement of any output transformers. Being designed for professional audio installation market, special care was taken for long term cost of ownership parameters: In addition to remarkably low current consumption and heat dissipation, the CPS4.5 provides remote standby switching with just 5 Watts consumption in standby mode.

Electro-Voice CPS4.5 Features

  • Four channels in one compact rack-efficient unit
  • 500 W per channel
  • 70/100 V operation for distributed systems
  • Class-D design for optimum efficiency
  • Slot for optional RCM-810 module, allowing IRIS-Net control and monitoring
  • IRIS-Net selection of each channel's impedance (2-10 Ohms in 0.1 Ohms steps)
  • Rear-mounted attenuators
  • Switchable 50 Hz high-pass filter (Hi-Z mode)
  • Complete protection: thermal, overload, shorts, HF, DC, back-EMF, inrush current
  • Phoenix-type input and output connections
  • Remote power-on/off contact
  • Programmable power-on delay settings
  • Front-to-rear fans
