Find Where Adaptability Meets Functionality with the QSC CXD 4.2 Processing Power Amplifier

Product Features

  • Flexible Amplifier Summing Technology (FAST) drives most any loudspeaker system or configuration by distributing total amplifier power across one, two, three and all four channels.
  • Capable of providing up to 5,000 watts continuous and 8,000 watts peak with 70V or 100V on bridged output pairs.
  • Full function onboard loudspeaker processing DSP with crossover and parametric EQ Filters, limiting and alignment delay eliminate the need for outboard loudspeaker processors.
  • E Series Entertainment System DSP Tunings are now available for CXD processing amplifiers
  • PowerLight universal switch-mode power supply with PFC for highest efficiency, improved audio performance, and low heat dissipation.
  • Powerful Intrinsic Correction processing maximizes the sonic performance of QSC loudspeakers.
  • 20 factory preset configurations that can be modified and stored in the 50 user presets.
  • Integrated front panel with channel select and mute buttons, input and output LED metering, 400×240 LCD, intuitive navigation buttons, LED power button and indicator, and cast aluminum handles.
  • GPIO for additional functionality including a heartbeat output for life-safety supervision.
  • Four Phoenix input connectors, and four Phoenix touch-proof loudspeaker output connectors
