The BASIS platform meets the control, monitoring, signal transport and processing needs
of amplification and loudspeaker systems over an Ethernet network. The BASIS 922uz
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 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.
