QSC CX-Q 4K8 Eight-channel Network Amplifier for the Q-SYS Ecosystem
Spec Sheet 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 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. Features 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 – Eight 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 Specs General Specifications CX-Q 4K8 CX-Q 8K8 Typical distortion 8Ω 0.02 - 0.05% 4Ω 0.04 - 0.1% Maximum distortion 4Ω - 8Ω 1.0% Frequency response 20 Hz - 20 kHz +/- 0.3 dB Noise Unweighted output muted > 101 dB Weighted output muted > 104 dB Gain (1.2V setting) 35 dB 38 dB Damping factor > 100 Input impedance > 8k balanced and > 4k unbalanced Amplifier and load protection Short circuit, open circuit, over current, over voltage, thermal, RF,DC fault shutdown, active inrush limiting, on/off muting AC power input Universal power supply 100 - 240 VAC, 50 - 60 Hz Agency approvals UL, CE, RoHS/WEEE compliant, FCC Class B (conducted and radiated emissions) Carton contents IEC cable, quick start guide, Euro (green) connectors Power Specifications CX-Q 4K8 CX-Q 8K8 Max Power Max Power 8 Independent Channels A, B, C, D, E, F, G, H 70V 1000 W 1250 W 100V 1000 W 1250 W 8Ω 1000 W 1250 W 4Ω 1000 W 1500 W 2Ω 800 W 1000 W 2 Channels BTL BridgedA+B or C+D or E+F or G+HDoubles Voltage 140V 1500 W 2000 W 200V 1500 W 2000 W 8Ω 1500 W 3000 W 4Ω 1400 W 1700 W 2Ω NR* NR* 2 Channels ParallelAB or CD or EF or GHDoubles Current 70V 1500 W 2000 W 100V 1500 W 2000 W 8Ω 1000 W 1250 W 4Ω 1250 W 2400 W 2Ω 1500 W 2500 W 3 Channels Combined in ParallelABC or EFGTriples Current 8Ω 1000 W 1250 W 4Ω 1500 W 2000 W 2Ω 1500 W 2500 W 4 Channel Bridged/ParallelAB+CD, EF+GHDoubles Current and Voltage 8Ω 2500 W 4000 W 4Ω 3000 W 5000 W 2Ω NR* NR* 4 Channels Combined in ParallelABCD or EFGHQuadruples Current 8Ω 1000 W 1200 W 4Ω 2000 W 2400 W 2Ω 2500 W 4000 W 1Ω 3000 W 4000 W NR* = Not Recommended due to excessive current draw Controls, Indicators and Connections CX-Q 4K8 CX-Q 8K8 Controls and indicators (front) Power • Channel MUTE buttons • Channel SELECT buttons • Channel Input Signal and CLIP LED Indicators Channel Output and LIMIT LED meters • NEXT, PREV, ID buttons • Control knob Controls and indicators (rear) AC Power Disconnect (IEC C-14) Input connectors "Q" models - 3-pin Euro (green) and Q-LAN Network connectivity"Qn" models - Q-LAN Network connectivity only Output connectors 8-pin Euro (green) Weights and Dimensions CX-Q 4K8 CX-Q 8K8 Dimensions (H×W×D) mm 89 × 482 × 406 89 × 482 × 406 Dimensions (H×W×D) in 3.5 × 19 × 16 3.5 × 19 × 16 Weight net 11.3 kg / 25 lb 11.8 kg / 26 lb Weight shipping 13.2 kg / 29 lb 13.6 kg / 30 lb
