Q-SYS Ecosystem Integration – 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.

Network inputs only – “Qn” models are network input only (no local inputs) to reduce cost in scenarios where no local inputs are necessary.

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

    CX-Q Series

    (4-channel)

    Four-channel network amplifiers

    for the Q-SYS Ecosystem

    CX-Q Series network amplifiers combine

    the QSC legacy of robust power amplifiers,

    advancements in high-efficiency output

    devices and native network transport, control

    and monitoring capabilities of the Q-SYS

    Ecosystem.

    Native Q-SYS Integration

    CX-Q Series amplifiers are fully native

    components of the Q-SYS audio, video

    and control Ecosystem. Like all Q-SYS

    peripherals, CX-Q Series amplifiers offer

    simple drag-and-drop integration into your

    Q-SYS design, enabling network routing,

    advanced processing (including Intrinsic

    Correction™ custom voicings for QSC

    loudspeakers) and control. This expedites

    the installation process and provides superior

    system performance far beyond that of thirdparty amplifier solutions.

    It also means that the Q-SYS Ecosystem can

    manage the fault protection and notification

    for these amplifiers. If for any reason an

    amplifier goes offline or has a fault, the

    Q-SYS system can alert the operator and

    ensure the system retains its integrity.

    Legacy of Power Redefined

    CX-Q Series network amplifiers use a

    5th generation high-efficiency, Class-D hybrid

    powertrain design built upon the dependable

    PL380 PowerLight™ amplifier platform. The

    new design offers both high voltage and high

    current operation with excellent audio quality

    and thermal performance.

    Channel Power Flexibility

    CX-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. 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).

    Collectively, these technologies decrease

    system cost by reducing wasted power and

    channels, while ultimately removing the need

    to specify multiple amplifiers with different

    power ratings in a multi-zone installation.

    Each model supports a wide variety of

    loudspeaker systems by featuring Low-Z, 70 V

    and 100 V direct drive on all channels.

    I/O Features

    Each amplifier also offers four channels of

    mic/line inputs (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. Additionally, eight

    bi-directional GPIO ports allow for further

    control and integration of other third-party

    peripherals within Q-SYS.

    Power & Space Efficiency

    CX-Q Series also features fully active 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 four channels of amplification

    addressable from the network in just 2RU and

    four channels of mic/line inputs, the CX-Q

    Series network amplifiers replace equipment

    taking up as much as four times the rack

    space.
