QSC CXD4.3Q-xx 4000W Q-SYS Network Amplifier 4 Mic/Line input channels. 900 watts/ch at 8Ω, 1400 watts/ch at 4Ω

QSC CXD4.3Q-xx 4000W Q-SYS Network Amplifier 4 Mic/Line input channels. 900 watts/ch at 8Ω, 1400 watts/ch at 4Ω

The QSC CXD-Q Series is designed as a representation of the revolutionary advancement in amplifier technology and innovation, along with outstanding integration capability as part of a Q-SYS system. CXD-Q is providing an extraordinary, robust and efficient high fidelity power, as it is designed specifically for the needs of integrators, to drive multiple channels and configurations of loudspeakers - all with rack space efficiency and optimal energy. The CXD-Q Series consists three powerful, four-channel amplifiers, each a Q-SYS peripheral enabling processing, control and audio routing. In the amps is provided already the capability to combine and configure channels in many different ways to drive a wide range of loudspeaker systems including 70V and 100V without the use of transformers. These amplifiers not only provide the processing and power that makes your system performance great, they are also offering the outstanding efficiency that ensures the energy cost will be kept to a minimum over the life of the installation. One of this series is QSC CXD4.3Q-xx 4000W Q-SYS Network Amplifier 4 Mic/Line input channels. 900 watts/ch at 8Ω, 1400 watts/ch at 4Ω.

Flexible Amplifier Summing

The QSC CXD-Q amplifiers are equipped with the Flexible Amplifier Summing Technology™ (FAST) actively, two, three or all four outputs. On the CXD4.3Q and CXD4.5Q, this power can also be used to drive 70V or 100V speaker lines directly from any one or all of the four outputs. This flexibility allows CXD-Q Series amplifiers to drive (for example) two full-range surface mounted speakers along with a subwoofer and one 100V distributed speaker line; or a high-power subwoofer and a bi-amplified full-range loudspeaker; three 70V distributed speaker lines and a low impedance surface mount speaker line; or a single high-power channel driving monster subwoofers.

Q-SYS Connectivity

From the strength of the Q-SYS platform is where the CXD-Q amplifiers benefits. These amplifiers are the true peripherals meaning that they have the capabilities to connect on a Q-LAN Ethernet source and network and receive audio signals. The CXD-Q amplifiers is offering eight bi-directional Q-SYS GPIO ports, in addition to the four Mic/Line input and output channels, for further interfacing with other equipment. Meaning, when the CXD-Q amps are in a Q-SYS design the Q-SYS Core manages the system amplifiers and design. Whatever the reason that will make the amplifier goes off or has a fault, the purpose of the Core is to alert the operator and ensuring also the system's integrity.

Power & Space Efficiency

CXD-Q Series amplifiers use QSC’s next generation class-D power amp design in combination with a custom power stage utilizing a new output device. These purpose built MOSFET devices provide high voltage operation without needing a full bridge output and offer better audio quality and thermal performance due to co-location of the semiconductors. CXD-Q amplifiers benefit from the proven PowerLight power supply, made even better with Power Factor Correction (PFC) that aligns the current waveform with the AC mains voltage waveform. PFC enables CXD-Q Series amps to draw current from the wall in a more efficient and controlled manner resulting in incredible power from a single standard AC breaker. The CXD-Q amplifiers also incorporate several energy conservation and efficiency strategies. One such tool is the unique multi-stage sleep mode that saves energy when possible without sacrificing performance. With four channels of Mic/Line input and four channels of amplification in just 2RU, the CXD-Q amplifiers replaces equipment taking up as much as three times the rack-space.

Integration Simplicity

Q-SYS is a complete integrated system that encompasses everything from the audio input to the output of the loudspeakers. As part of a Q-SYS system, the CXD-Q amplifiers are just some of the many peripherals that can be intuitively placed in a design and wired into the system. The centralized design maintains operational simplicity because not only does it allow for a “whole system” design philosophy, but the Q-SYS Core configures and manages all peripherals to ensure that all elements of the system are functioning correctly. With the complete integration facilities provided by Q-SYS, and the power efficiency provided by the custom MOSFET and FAST, the CXD-Q amplifiers are perfect for nearly every installation application.
