The rear panel of the Page Station offers a variety of auxiliary audio I/O interfaces and GPIO for expanding its capability. The auxiliary audio inputs can
accommodate accessories such as a secondary microphone or an MP3 audio source. The Page Station auxiliary output can drive an amplifier input,
powered loudspeaker or other destination device. And the Page Station GPIO interface can be configured to use external events to affect paging
operation or to be the source of events to affect external control systems.
The Q‑Sys Q‑LAN Network
The Q-Sys solution is designed to be deployed on QSC’s high performance Q-LAN network
(Figure 1)
. Q-LAN is a proprietary time-sensitive gigabit
Ethernet 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.
Figure 1
shows a very simple Q-LAN network implementation with a Q-Sys Core, a Q-Sys I/O Frame, Ethernet switch, and a Q-Sys Page Station.
All devices are connected to a managed Gigabit Ethernet switch that includes the appropriate QoS (Quality of Service) suitable for a high-performance
gigabit network to support multimedia applications. The network switch is also a PSE device, offering a number of PoE ports to power the Q-Sys Page
Station devices.
The Page Stations can be configured via Q-Sys Designer to source page announcements or prerecorded audio streams to the Q-Sys Core. The Q-Sys
Core can then redistribute these announcements or audio streams throughout the facility by forwarding them (with or without additional signal
processing) to Q-Sys I/O Frames. The Q-Sys I/O Frames can then drive the inputs of QSC amplifiers or powered loudspeakers.
Note that a PC or laptop 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.
There are no special unpacking precautions. However, it is recommended that you keep the original packing materials for reuse in the rare event that
service is required. If service is required and the original packing material is not available, ensure that the unit is adequately protected for shipment
(use a strong box of appropriate size, sufficient packing/padding material to prevent load shifting or impact damage) or call QSC’s Technical Services
Group for replacement packing material and a carton.

Windows Based Computer
A PC or laptop running Q-Sys Designer or remote management
application. This computer is required only during the design and
configuring the system. The computer is not required for runtime
operation, though it may be used for on-going system management.
Q-Sys Page Station
In conjunction with the Q-Sys Core, the Page Station
provides paging services for the Q-Sys system. All audio and
management communication traverse the Q-LAN network.
