Built for system integrators, the CXD series amplifiers provide multi-channel amplification with built-in DSP and enough power to drive wide varieties of speaker systems with optimal energy efficiency. The CXD Series consists of 3 lightweight, 2RU, 4-channel amplifiers with onboard DSP and flexible channel combining as well as 70V and 100V direct drive. These amplifiers not only provide the power and processing to make your system perform better, they offer outstanding efficiency ensuring that energy costs are kept to a minimum over the life of the installation.

QSC CXD4.2 Features

  • Flexible Amplifier Summing Technology (FAST) drives most any loudspeaker system or configuration by distributing total amplifier power across one, two, three or all four channels.
  • Full function onboard loudspeaker processing DSP with Crossover and Parametric EQ Filters, Limiting and Alignment Delay eliminate the need for outboard loudspeaker processors.
  • PowerLight universal switchmode power supply with PFC for highest effiency, improved audio performance, and low heat dissipation.
