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.
