  • Seamless Q-SYS™ integration with audio transport and control via standard Gigabit Ethernet protocols and hardware.
  • Capable of providing up to 4,000 W peak and 2,500 W continuous with Low-Z, 70V, or 100V direct drive available on all channels.
  • Eight-channel CXD-Qn models are “network input only” (no analog inputs) to reduce system cost.
  • Touch-proof Euroblock loudspeaker connections.
  • Flexible Amplifier Summing Technology™ (FAST) permits up to four channels to be combined for higher output power.
  • PowerLight universal switchmode power supply with PFC for highest efficiency, and low weight.
  • 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.
