CPS 4.5

500 W/CH 4‑CH amplifier

  • 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
  • Remote power-on/off contact
  • Programmable power-on delay settings
  • Front-to-rear fans
