“Q-SYS is the new century’s version of the old system, with a lot more power, capability, expandability
and far less hardware. When you add it all up, Q-SYS knocked everything else off the charts.”
Rod Sintow, Pro Sound & Video — Florida and California
Network redundancy may be
implemented by simply adding additional
network switches and cabling. In the
event of a network failure, the Q-Sys
components switch over instantly to the
back-up network.
I/O Frame redundancy gives the
designer the option of adding redundant
I/O peripherals for high-priority areas.
Total System redundancy eliminates any
single point of failure by combining all
fourprimaryredundancytypes:network,
Core, I/O, and amplifier.
N +1 Amplifier redundancy is made
possible with the QSC DAB-801 (DataPort
amplifier backup panel), which configures
five 2-channel QSC DataPort amplifiers so
that the fifth amplifier automatically kicks
in if a problem is detected with any of the
other four (4 + 1 redundancy). A second
DAB-801 may be added to implement
8 + 1 redundancy. When 4-channel
amplifiers are selected, a single
DAB-801 provides 2 + 1 redundancy,
while adding a second DAB-801 will
implement 4 + 1 redundancy.

I/O Peripherals
I/O Frame
The Q-Sys™ I/O Frame provides the
points of connection that interface Q-Sys
with other components of the audio
system, including microphones, mixers
and power amplifiers. The I/O Frame
converts analog audio input signals to
digital and passes them over the network
to the Core. The I/O Frame also receives
the processed digital audio signal back
from the Core, converts it back to analog
and feeds it to the output devices.
High-performance A/D and D/A converters
are used to ensure audiophile quality
throughout. In the case of the Q-Sys Core
250i and 500i, the I/O Frame and the
Core are integrated into a single unit.
I/O Cards
Typically located near an audio source or
destination, each I/O Frame enables up
to 16 channels of input and/or output by
housing up to four cards, which may be
mixed and matched in a single unit. The
following cards are available for both the
integrated Cores (up to eight cards total)
andtheI/OFrame:
• Mic/Line Analog Input Card (CIML4/
CIML4-HP) — Four channels of
switchable mic/line-level analog audio
input with 48 V phantom power.
This input card provides the interface
between Q-Sys and input devices
such as microphones, mixers, and CD/
DVD players. The input card is also
available in a high performance version
(CIML4-HP) featuring broadcast quality
pre-amps and A/D converters.
