The Q-SYS DPA-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.


  • Seamless Q-SYS integration with audio transport and control via standard gigabit Ethernet protocols and hardware
  • Capable of providing up to 2,000 W of power
  • Hybrid circuit topology mixing the robustness of the PL380 PowerLight™ amplifier platform with new high-voltage output devices
  • FlexAmp™ allows for asymmetric power distribution across amplifier channels
  • Flexible Amplifier Summing Technology™  optimizes for either higher voltage loads (up to 200 Vrms output) or high current loads (up to 35 A)
  • PowerLight universal switchmode power supply with PFC for highest efficiency, improved audio performance, and low weight
  • “Q” models offer mic/line inputs into the Q-SYS Ecosystem; “Qn” models are “network input only” to reduce system cost
  • Touch-proof Euroblock loudspeaker connections
  • Eight bi-directional GPIO connections plus relay
  • Automatic energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality

DPA-Q Series amplifiers are fully native components of the Q-SYS audio, video and control ecosystem. Like all Q-SYS peripherals, DPA-Q Series amplifiers offer simple drag-and-drop integration into your Q-SYS design, enabling network routing, advanced processing (including Intrinsic CorrectionTM custom voicings for QSC loudspeakers) and control. This expedites the installation process and provides superior system performance far beyond that of third-party amplifier solutions.

It also means that Q-SYS can manage the fault protection and notification for these amplifiers. If for any reason an amplifier goes offline or has a fault, Q-SYS can alert the operator and ensure the system retains its integrity.

DPA-Q Series network amplifiers use 5th generation high-efficiency, Class-D hybrid powertrain design built upon the dependable PL380 PowerLightTM amplifier platform. The new design offers both high voltage and high current operation with excellent audio quality and thermal performance.

“Q” models offer eight channels of mic/line input (with +12 V phantom power) directly on the back of the amplifier that act as Q-SYS on-ramps in addition to its amplification duties. “Qn” models are network input only to simplify system design and reduce system cost when additional inputs are not needed. Both models provide eight bi-directional GPIO ports and one relay within Q-SYS for further control and integration of other third-party peripherals.

DPA-Q Series also utilizes Power Factor Correction (PFC) which aligns the supply 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.

This series also incorporates several energy conservation and efficiency strategies, including 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 DPA-Q Series network amplifiers replace equipment taking up as much as four times the rack space.

DPA-Q Series network amplifiers combine two technologies that provide extreme flexibility in output deployment. FlexAmp™ allows for asymmetric output channel loading by drawing from large power reserves and distributing customized output power levels per channel. This can be especially useful for screen channel speakers, delivering more power to the LF section compared to the higher efficiency HF section, and for immersive surround speakers, delivering more power to the object-based speakers that demand it during soundtrack playback. FAST (Flexible Summing Amplifier Technology™) allows channels to be combined in bridge mode, parallel mode or bridge/parallel mode to deliver either higher voltage loads (up to 200 Vrms output) or higher current loads (up to 35 A).
