processing allows the system’s full power to
be flexibly allocated as needed, without the
capacity chokepoints inherent in distributed
processing. That vastly simplifies the job of
audio system design, allowing any input to
be routed to any output without convoluted,
variable-latency signal paths. And it also keeps
system redundancy very straightforward.
Centralized architecture also enables more
efficient networking. Because the Core
handles all control and monitoring, fewer
control connections are needed for remote
devices. Less traffic takes up less bandwidth,
leaving greater overall system capacity.
The Q-Sys Core is available in three sizes
tailored to the varying requirements of
differentfacilities:Core1000,Core3000,
and Core 4000.
I/O Frame
Physically located near audio sources and
destinations, I/O Frames provide the points
of connection used to interface Q-Sys with
other components of the audio system,
such as mixers and power amplifiers. Each
I/O Frame enables up to 16 channels of
input and/or output by housing up to four
of the following I/O cards, which may be
mixedandmatchedinasingleunit:
• Mic/Line Input card — Four channels
of switchable mic/line-level analog
audio input with 48V phantom power
(available with standard or premium
pre-amps and A/D converters).
• Line Output card — Four channels of
balanced, line-level analog output.
• DataPort Output card — Four audio
output channels (2 DataPorts) for
connection to DataPort equipped
QSC amplifiers.
• AES Input/Output card — Four input
and four output channels of AES-3
digital audio.
• CobraNet Input/Output card — Up
to 32 input and 32 output channels
available when used in a core, 16 x 16 in
an I/O Frame.
Additional cards are under development; check
the QSC website for the latest information.
