DSP 322ua
QSControl.net Digital System
QSControl.net, QSC’s next generation network
audio system, achieves the seamless integration of
the company’s control, processing, and 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 DSP devices are designed to operate under
the company’s QSControl.net platform.
Analog DSP 322ua
The DSP 322ua meets the processing needs of today’s
demanding audio systems. Controlled over an Ethernet
network using QSC’s Venue Manager software, this
newest generation of DSP devices are fully configurable.
Storing up to 8 signal flow design configurations with
nearly unlimited snapshot parameter recall, the DSP
322ua can fit any application. And with all data stored in
the device memory, files can be uploaded from the unit
to multiple computers without complications.
• Configurable DSP functions and signal paths
Through QSControl.net, QSC’s BASIS and next-generation
RAVE and DSP products can be networked 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.
• Matrix mixer – any size, up to 24 x 24
Fixed Latency DSP
Users of most other configurable DSP systems are
familiar with a variable latency inherent in the processing
configuration. Add more processing blocks and you
also add delay, whether you want it or not. QSC’s DSP
engine is unique in having a short and fixed processing
latency through the DSP subsystem. When the A/D and
D/A converters are included, the total analog-to-analog
latency of a single unit is a negligible 2.354 milliseconds.
QSC’s fixed latency DSP is configurable DSP that stays
fast and predictable from one configuration to the next.
