CX-Q Series (8 channel)
Eight-channel network processing 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 QSYS 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 third-party 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 FE ATU R ES
Each amplifier also offers eightchannels 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.
