QSC CXD8.8Qn Multi-Channel 1000W/CH Q-SYS Amplifier Supports 2Ω-16Ω Low-Z operation as well as 70V and 100V High-Z operation

The QSC eight-channel CXD-Q and CXD-Qn Series amplifiers 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 and CXD-Qn 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 eight channel CXD-Q and CXD-Qn Series consists of an 8,000W and 4,000W amplifier each. All models providing full Q-SYS capability with 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 them is the QSC CXD8.8Qn Multi-Channel 1000W/CH Q-SYS Amplifier Supports 2Ω-16Ω Low-Z operation as well as 70V and 100V High-Z operation.

Flexible Amplifier Summing

CXD-Q Series amplifiers feature Flexible Amplifier Summing TechnologyTM (FAST) that enables the eight channels to be combined in banks of two with up to four channels combining in each bank for higher output power. With their +/- 150V rails, each channel on the CXD-Q Series amplifiers is capable of driving Low-Z, 70V, or 100V loads directly. 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

The CXD-Q and CXD-Qn Series amplifiers are part of the Q-SYS Platform. They are true Q-SYS peripherals which means that they have the ability to connect on a Q-LAN Layer-3 network with the capability to receive and source signals. The CXD-Q models are offering eight channels of mic/line input (with +12V phantom power) directly on the back of the amplifier that is acting as a Q-SYS on-ramps in addition to amplification. The CXD-Qn models are network input only simplifying simple designed and reducing the system cost when additional input are not needed. For more and further interfacing with other equipment, both models are providing eight directional GPIO ports within the Q-SYS Platform. Meaning that also the Q-Sys Platform are able to manage the fault notification and protection for these amplifiers. Whenever or whatever the reason the amplifier suddenly goes offline or has a fault, the platform will alert the operator and ensuring the system's integrity.

Power & Space Efficiency

The CXD-Q and CXD-Qn Series eight channel amplifiers use QSC’s fifth generation class-D power amplifier design providing high voltage operation and offer outstanding audio quality and thermal performance. They benefit from the proven PowerLight power supply made better with Power Factor Correction (PFC) that aligns the current waveform with the AC mains voltage waveform. PFC enables these amplifiers to draw current from the wall in a more efficient and controlled manner resulting in incredible output power from a single standard AC breaker. This series also incorporates several energy conservation and efficiency strategies, one of which is a unique multi-stage sleep mode that saves energy when possible without sacrificing performance. With eight channels of amplification addressable from the network in just 2RU and eight channels of mic/line inputs on the “Q” models, the CXD-Q amplifiers replace equipment taking up as much as three times the rack space.

Integration Simplicity

The Q-SYS Platform 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 and CXD-Qn Series 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 Q-SYS configures and manages all peripherals to ensure that all elements of the system are functioning correctly.


  • Seamless Q-SYS integration with audio transport and control via standard Gigabit Ethernet protocols and hardware.
  • Capable of providing up to 8,000 W peak and 5,000 W continuous with Low-Z, 70V, or 100V direct drive available on all channels.
  • Eight-channel CXD-Qn models are “network input only” (no analog inputs) to reduce system cost.
  • Touch-proof Euroblock loudspeaker connections.
  • Flexible Amplifier Summing Technology™ (FAST) permits up to four channels to be combined for higher output power.
  • PowerLight universal switchmode power supply with PFC for highest efficiency, and low weight.
  • Eight bi-directional GPIO connections that can be used for analog or digital inputs or outputs to/from Q-SYS.
  • Built-in energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality.
