CXD4.5Q

Processing Amplifier


Features

  • Seamless Q-SYS integration with audio transport and control via standard Gigabit Ethernet protocols and hardware.
  • Capable of providing up to 5,000 watts continuous and 8,000 watts peak with 70V or 100V direct drive available on each output of the CXD4.3Q and CXD4.5Q, and on bridged output pairs of the CXD4.2Q.
  • Flexible Amplifier Summing Technology™ (FAST) permits total amplifier power to be distributed across one, two, three, or all four channels.
  • PowerLight universal switch mode power supply with PFC for highest efficiency, improved audio performance, and low weight.
  • Mic/Line input Euroblock connectors and touch-proof Euroblock loudspeaker connections.
  • Eight bi-directional GPIO connections that can be used for analog or digital inputs or outputs to/from Q-SYS.
  • Built-in energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality.
  • Q-SYS technical support is available 24/7 - worldwide
