QSControl.net, QSC’s next generation network audio 
system, achieves the seamless integration of the 
company’s signal transport, 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 BASIS devices 
are designed to operate under the company’s 
QSControl.net platform.
BASIS 922dz
The BASIS platform meets the control, monitoring, signal 
transport and processing needs of amplification and 
loudspeaker systems over an Ethernet network. The BASIS 
922dz units combine three distinct QSC technologies 
within a single hardware unit. Amplifier and loudspeaker 
control, monitoring and protection, configurable DSP, and 
CobraNet™ audio transport are seamlessly integrated into 
one powerful single RU package. 
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.
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 digital-to-analog latency 
of a single unit is a negligible 2.167 milliseconds. QSC’s 
fixed latency DSP is configurable DSP that stays fast and 
predictable from one configuration to the next.
