BASIS 722az - Full Compass
BASIS 722az Digital System, QSC’s next generation network
audio system, achieves the seamless integration of
the company’s control, processing, and monitoring
technologies. 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 platform.
BASIS 722az
The BASIS platform meets the control, monitoring and
processing needs of amplification and loudspeaker systems
over an Ethernet network. The BASIS 722az units combine
two distinct QSC technologies within a single hardware
unit. Amplifier and loudspeaker control, monitoring and
protection, and configurable DSP are seamlessly integrated
into one powerful single RU package.
Through, 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.

• Amplifier and loudspeaker control, monitoring and protection
• Configurable DSP functions and signal paths
• Fixed latency DSP engine
• Ethernet controllable
• Each unit can store eight design configurations that can be changed on the fly
• Snapshots can recall config or block and/or parameter settings
•THX™ approved for professional cinema applications
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
• Graphic equalizers
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.
