Introduction
Q-Sys is a platform of software and hardware products that provide the system designer and system operator with all the tools necessary to design,
configure, and manage medium to large scale audio systems. In addition to the primary signal processing and system management components that
make up a Q-Sys audio system, the Q-Sys solution includes peripheral components that offer services including conferencing, paging, remote and
mobile control. This manual addresses the features and specifications related to the hardware components of the Q-Sys I/O-22 peripherals.
Q-Sys operates on the Q-LAN network. Q-LAN is a third-generation networked media distribution technology providing higher quality, lower latency
and greater scalability when compared to its third generation peers and previous-generation audio networks. Q-LAN operates over gigabit and higher
rate Ethernet variants. Q-LAN is a central component of QSC’s comprehensive Q-Sys integrated system platform. Interactive integration with Q-Sys
means that Q-LAN can be configured and monitored using the graphical and scripting tools available on the Q-Sys platform.
The Q-Sys I/O-22 is a sophisticated network device that provides microphone and line level inputs, line level outputs, and amplification services for
a Q-Sys audio system. Like all Q-Sys system components, functionality of the I/O-22 is defined and configured by the system designer using Q-Sys
Designer. Q-Sys Designer is Windows-based software used to design, and optionally manage, a Q-Sys system. Once a Q-Sys design file has been
created, it is then deployed to a Q-Sys Core Processor over the Q-LAN network. The Q-Sys Core Processor is the centralized processing entity for the
Q-Sys system. And as such, the Q-Sys Core Processor pushes all necessary design and configuration information to each end node in the system,
including the I/O-22.
The I/O-22 connects to a Q-Sys system by joining the Q-LAN network. Once connected to the network, the Q-Sys Core Processor can automatically
discover the I/O-22 device, assimilate it into the Q-Sys system and push the appropriate configuration, as defined in the Q-Sys Designer design file,
to the I/O-22. Once assimilated into the Q-Sys system, the I/O-22 can be used, without further need of a PC connected to the network, running
Q-Sys Designer.
I/O-22 Features
• The I/O-22 is a network enabled, Power over Ethernet (PoE) device. The I/O-22 products are designed to connect to a Q-Sys system via Q-LAN
to which the system Core Processor(s) is connected. Q-Sys, via the Q-LAN network, provides configuration and management services to all Q-Sys
products and peripherals in the system, including the I/O-22.
• In addition to, or instead of PoE, the I/O-22 can be powered by an external 24 VDC power supply.
ROTE!:
Power must be supplied by PoE or the AUX PWR external power supply.
AUTIORG!:
The power supply used to provide 24 VDC power to the unit shall be a UL Listed ITE power supply, marked LPS, or a UL
Listed direct plug-in power unit, marked Class 2, with a rated output of +24 VDC, 30 watts minimum, 1.25 A.
• The I/O-22 is an Input/Output device. Analog input sources can be connected to the I/O-22 and the analog audio is converted to digital audio and
sent over the Q-LAN network to the Core for Processing. Likewise, digital audio can be sent from the Core over the Q-LAN network to the I/O-22
which converts the digital signal to analog for local use.
• The I/O-22 has two General Purpose Input Output (GPIO) connectors providing digital input and output control signals.
• The RS-232 connector on the I/O-22 allows you to make a connection to the Serial Port and Control Script components in a Q-Sys design. When a
connection is made, and an appropriate Lua script written, you can control and read from devices such as DVD players, recording hardware, video,
lighting, and so on.
• The I/O-22 includes an amplifier that can power a small (4 or 8 ohms) local loudspeaker (not included).
• The I/O-22 includes a quick-release Mounting Bracket for mounting in various situations.
