RAVE 520uz
QSControl.net™ Digital System
Inputs
QSControl.net, QSC’s next generation network audio
system, achieves the seamless integration of the
company’s signal transport, control, processing, and
8 universal mic/line
monitoring technologies. QSControl.net brings together

QSC’s digital, power amplification and loudspeaker
products into a unified system that enables the user
to administrate it all via a fully integrated graphical user
interface. The new generation RAVE devices are designed
to operate under the company’s QSControl.net platform.
Features
• Configurable DSP functions and signal paths
RAVE 520uz
• Fixed latency DSP engine
The RAVE platform meets the processing and signal
• Ethernet controllable
transport needs of audio systems over an Ethernet
• CobraNet audio transport with new intuitive GUI
network. The RAVE 520uz units combine two distinct QSC
DSP, and CobraNet™ audio transport are seamlessly
• T wo Ethernet ports – CobraNet and control can be run over a single cable
or be divided between the two ports. The CobraNet port is 100Base-T. The
control port is 10Base-T
integrated into one powerful single RU package.
• Each unit can store eight design configurations that can be changed on the fly
Through QSControl.net, QSC’s BASIS™ and next-
• Snapshots can recall config or block and/or parameter settings
generation RAVE and DSP products can be networked
• THX™ approved for professional cinema applications
technologies within a single hardware unit. Configurable
together and controlled from a single software interface.
In addition, multiple networked computers can be set up
to control and monitor all of the units simultaneously.
Fixed Latency DSP
Users of most other configurable DSP systems are
familiar with a variable latency inherent in the processing
DSP functions include, but are not limited to:
• Matrix mixer – any size, up to 24 x 24
• Automixers – gain sharing
• Routers – any size, up to 24 x 24
• Gain controls – any channel count, up to 24
configuration. Add more processing blocks and you also
• Graphic equalizers
add delay, whether you want it or not. QSC’s DSP engine
• F ilters – high-pass, low-pass, all-pass, shelf, parametric, parametric shelf,
Butterworth high and low-pass, Linkwitz-Riley high and low-pass, BesselThomson high and low-pass
is unique in having a short and fixed processing latency
through the DSP subsystem. QSC’s fixed latency DSP is
a configurable DSP that stays fast and predictable from
one configuration to the next.
