0.396 milliseconds. When analog input and analog outputs
are used, the total delay is 2.354 milliseconds. The delay
does not change regardless of the DSP configuration, unless
the configuration intentionally adds more delay.
The BASIS 914lz also supports the new optional low-latency
CobraNet feature that provides transport at only 2.66 milli-
seconds delay. Thus the delay from analog to analog across
the network can be less than 6 milliseconds, fast enough
not only for large audio distribution but for the most critical
real-time live performance work.
Both software and firmware can be easily updated over the
network. In the future, QSC will be adding new capabilities
to both BASIS and QSControl.net. Our latest code releases
and access to up-to-date information on BASIS and QSCon-
trol.net are available at www.qscontrol.net. We invite you
to visit us there.
We've applied our many years of experience in supporting
high-end installed sound with our previous system-building
products such as RAVE, QSControl, CM16a, DSP-3, DSP-4,
and DSP-30. The BASIS 914lz brings all that technology
together in one compact, powerful, easy to use system. We
are confident that your new BASIS 914lz will provide years
of dependable service and we hope it will help you, the sys-
tem designer and implementer, to express your creative
audio system ideas.
