QSControl.net Digital System
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 914lz
The BASIS platform meets the control, monitoring, signal
transport and processing needs of amplification and
loudspeaker systems over an Ethernet network. The BASIS
914lz 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.
• Ethernet controllable
4 XLR line level 32
• Amplifier and loudspeaker control, monitoring and protection
• Configurable DSP functions and signal paths
• Fixed latency DSP engine
• CobraNet audio transport with new intuitive GUI
•Two 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
• 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:
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.
• Gain controls – any channel count, up to 24

8(16 channels) Features
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.
