QSC CX-Q 2K4 Four-Channel Network Amplifier
The QSC CX-Q 2K4 is a native Q-SYS platform network amplifier delivering up to 2,000 W of total power across four channels. Built on the proven PL380 PowerLight™ Class-D hybrid powertrain, it offers high efficiency, superior thermal performance, and seamless drag-and-drop integration into Q-SYS audio designs. Certified for both Google Meet and Microsoft Teams, it provides network control, monitoring, and protection within a 2 RU form factor.
Featuring FlexAmp™ technology for asymmetric channel loading and FAST™ (Flexible Summing Amplifier Technology) for bridge, parallel, or bridge/parallel configurations, the CX-Q 2K4 ensures optimal power distribution. Each channel supports Low-Z, 70 V, or 100 V direct drive and includes four mic/line inputs with +12 V phantom power, eight GPIO ports, and touch-proof Euroblock outputs.
