QSC CX-Q 4K8

QSC CX-Q 4K8 Q-SYS Eight-channel Network Amplifier

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 of the Q-SYS Ecosystem. CX-Qn 4K8 features eight 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.

Q-SYS Ecosystem Integration – 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.

Network inputs only – “Qn” models are network input only (no local inputs) to reduce cost in scenarios where no local inputs are necessary.
