The Electro-Voice CPS 4.5 is a 500 W per channel 4-channel amplifier and 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 Ω in 0.1 Ω 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
