Q-SYS CX-Q Series network amplifiers combine a legacy of robust power amplifiers, advancements in high-efficiency output devices and native network transport, control and monitoring capabilities. CX-Q 4K4 features four channels, capable of delivering customized power output loading and a total maximum power of up to 4000 W. Low-Z, 70 V or 100 V direct drive are available on all channels.
Build for Q-SYS
– Simple drag-and-drop integration into your Q-SYS design, enabling network routing, advanced processing and control.
Legacy of power redefined
– These network amplifiers are built with a 5th generation high-efficiency, Class-D hybrid powertrain design built upon the dependable PL380 PowerLight™ amplifier platform.
Flexible & efficient channel power distribution
– CX-Q Series network amplifiers feature FlexAmp™ and FAST (Flexible Amplifier Summing Technology™), which combine to provide extreme flexibility in output deployment.
Routable input options
– Four channels of mic/line inputs (with +12 V phantom power) for additional on-ramps into Q-SYS.
Additional Features
- PowerLight universal switchmode power supply with PFC for highest efficiency, improved audio performance and low weight
- Touch-proof Euroblock loudspeaker connections
- Eight bi-directional GPIO connections for further control and integration of third-party peripherals within Q-SYS
- Automatic energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality
