Introduction

Q-Sys is a platform of software and hardware products providing system designers and operators with 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 such as remote management and paging. This manual addresses the features and specifications related to the hardware components of the Q-Sys networked page station peripherals.

The Q-Sys Page Stations are network devices that provide paging services for a Q-Sys audio system. Like all Q-Sys system components, functionality of the Page Stations are defined and configured by the audio system designer using Q-Sys Designer. Q-Sys Designer is Windows-based software used to design, and manage, a Q-Sys system. (For information about configuring the Page Station, refer to the Q-Sys Designer Online Help.) Once a Q-Sys design file has been created, it is then deployed to a Q-Sys Core over the Q-LAN network. The Q-Sys Core is the centralized processing entity for the Q-Sys system. And as such, the Q-Sys Core pushes all necessary design and configuration information to each end node in the system including Page Station peripherals.

The Page Stations connect to a Q-Sys system by joining the Q-LAN network. Once connected to the network, a Q-Sys Core can automatically discover the Page Station, assimilate it into the Q-Sys system and push the appropriate configuration to the Page Station, as defined in the Q-Sys Designer design file. Once assimilated into the Q-Sys system, the Page Station can be operated entirely via its front panel user interface (UI) and microphone without further need of a design computer in the system.

Page Station Description

The Q-Sys Page Station is a networked page station that connects to a Q-Sys system via Q-LAN. All audio deliveries to and from the Page Station use the Q-LAN network. The Page Station provides two Q-LAN network interfaces for connecting to the Q-Sys system. This allows Page Stations to connect to two switch ports or to be deployed on two separate networks to support a variety of redundant operation modes for mission critical applications.

The Q-Sys Page Station comes in four different models: PS-400, PS-800, PS-1600, and PS-1650. Each of these models has a handheld microphone version (indicated by an "H" in the Model number), and a goosenck microphone version (indicated by a "G" in the Model number). The differences are indicated in the table below.

Model	Total Buttons	Command Buttons	Keypad Commands	Security
PS-400	4	Four Buttons	No	No
PS-800	8	Eight Buttons	No	No
PS-1600	16	Four Buttons	Yes	Yes
PS-1650	16	Sixteen Buttons	No	No

Command Buttons - Assign Commands to the available buttons.
- Keypad Commands - Has a numeric keypad; you can specify the Commands that can be entered using the keypad.
- Security - Sets Automatic logoff timeout, logon requirements, and restricts Users. A Page Station must have a keypad to have security requirements.

Power

In addition to audio and data deliveries via Q-LAN, the Page Station is designed to receive its power from the Q-LAN network via IEEE 802.3af compliant power sourcing equipment (PSE). This technology is better known as PoE (Power over Ethernet). A PSE node can be an appropriate PoE enabled switch port or a PoE enabled power injecting device. When both Q-LAN ports on the Page Station are connected to PoE enabled sources, the Page Station enters a load sharing mode that balances the power draw from each source to supply the page station. Should a port failure event occur, the page station draws the full power load required from the remaining healthy PoE enabled source. The Page Station can also be operated from a separate +24 VDC power supply in applications where PoE power is unavailable or undesirable.

User Interface

The Q-Sys Page Stations provide a front-panel user interface that includes a 16-, 8-, or 4-button capacitive-touch keypad. The keypad offers visible feedback and tactile cues, yet there are no buttons or membranes to wear out. Paging status, operational detail and alerts are also reported via illuminated status indicators and the station's 240x64 monochrome graphics LCD.

Microphones

For Page Stations with the letter H in the model number, voice input is provided through a push-to-talk, dynamic paging microphone. A unique magnetic docking system and cable strain relief allow flexibility in microphone placement when not in use. The letter G in the model number indicates a dynamic gooseneck microphone.

Inputs and Outputs

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.

Page Station Configuration and Setup

Q-Sys Designer is the software application required to configure your paging system. Refer to the Q-Sys Designer online help for details.

This section covers connecting the hardware to the Q-LAN network, powering up, and re-setting the Page Station to the factory defaults.

Optional Connections

The following are optional, and should be connected prior to powering up the Page Station.

• MIC/LINE (3-Pin Euro)
  LINE OUT (3-Pin Euro)
  GPIO
• AUX POWER (If you make this connection and plan to use PoE, do not turn the auxiliary power supply on until you have made the network connection with PoE turned on. See About PoE and AUX POWER, page 11)

Required Connections

• LAN-A - Connect one end of a CAT-5e cable with an RJ45 connector to the LAN-A connector on the Page Station. Connect the other end of the cable to the Q-LAN network.
• Connect LAN-B in the same way if you are going to be using LAN-B.

When power is supplied to the Page Station it may take several minutes to boot fully. The message "Q-Sys not configured" displays. This message remains until the network details are configured for the Page Station and it is included in a valid paging design.

About PoE and AUX POWER

There is no On/Off switch for the Page Station, making the order in which the power is connected important. The following information describes the events when power is lost based on which power is supplied to the Page Station first.

If AUX POWER is supplied first:

• The Page Station boots using AUX POWER.
  If PoE is then connected, it is not used.
• If AUX POWER fails, power to the Page Station is lost, the Page Station re-boots using PoE.

• If PoE fails with AUX POWER still available, there is no effect - PoE was not being used.

• If PoE is supplied first:

• The Page Station boots using PoE.

• If AUX POWER is then connected, it is not used.
• If PoE fails, the Page Station switches to AUX POWER. There is no re-boot.
• If AUX POWER fails with PoE still available, there is no effect AUX POWER was not being used.
• If PoE returns, the Page Station remains on AUX POWER.

Wall-mounting the Page Station

NOTE: The product shall be installed in accordance with the applicable code requirements.

Q-Sys Page Stations are designed to be mounted on a wall or podium with an appropriate cutout and cavity to allow all cables and power sources to connect to the Page Station rear panel with adequate stress relief. The included Mounting Bracket is designed to mate with a standard triple-gang U.S. electrical box, but does not need one to be mounted. Using an electrical box provides contractors with the option of pre-wiring, then installing the Page Station at a later time; if an electrical box is used, its dimensions should meet the NEMA standards. The Mounting Bracket should be firmly attached to the wall using the electrical box (if installed) for alignment only.

1. Remove the Mounting Bracket from the Page Station. It is secured by one screw on the bottom of the Page Station. Set the screw aside for later use.
2. Route all Page Station wiring and connectors through the center of the Mounting Bracket.
