The Q-Sys Q-LAN Network
The Q-Sys solution
(Figure 4)
is designed to be deployed on QSC’s high performance Q-LAN network. Q-LAN is a proprietary network
implementation that bundles several industry standard protocols into a data transport solution appropriate for live performance multimedia
environments. Q-LAN offers gigabit data rates, device and network redundancy, 32-bit floating point audio data transfers, and low-latency support on
local area network deployments. Accurate synchronization of end nodes and high-quality clock distribution are built into the Q-LAN solution using
the IEEE-1588 Precision Time Protocol. Discovery of end nodes and auto-configuration of end nodes are all included in the solution using industry
standard protocols over a standards-based IP network implementation that utilizes off-the-shelf hardware components.
The figure below shows a very simple Q-LAN network implementation with a Q-Sys Core Processor, a Q-Sys I/O Frame, a Q-Sys TSC-8 touchscreen
controller, Ethernet switch, and a PC running Q-Sys Designer.
All devices are connected to a managed 1000 Mbps Ethernet switch that includes the appropriate QoS, (Quality of Service) suitable for a
high-performance gigabit network to support multimedia applications.
The TSC-8 can be configured via Q-Sys Designer to provide remote management services for the Q-Sys system. Services may include level control,
audio source selection, room combining, and so on. All management requests from the TSC-8 touchscreen controller are forwarded to the Q-Sys Core
Processor. The Core Processor services these requests appropriately, either locally or by enlisting the appropriate system components such as I/O
Frames or other peripherals.
NOTE!:
A PC is only required during initial configuration of the system or when a PC is the preferred means for providing on-going
management services to the system designer or operator.
• The Q-Sys I/O Frame provides an audio access point for the Q-Sys system by providing the means to get audio onto and off of the Q-LAN network.
• The Q-Sys Core Processor provides signal processing, distribution, and management services for the Q-Sys system. All time-sensitive audio and
management communications traverse the Q-LAN network.
• The Windows PC can be a desktop or laptop running the Q-Sys Designer or remote management application known as a User Control Interface
(UCI). The PC is only required by the Q-Sys system during the design phase for configuring the system. The PC is not required for runtime
operation, though it may be used for on-going system management
• The Q-Sys TSC-8, in conjunction with the Core Processor, provides dedicated remote management services for the Q-Sys system. All management
requests are directed through the Core Processor and traverse the Q-LAN network.
