PA Router
The PA Router is the hub of the Q-SYS Paging System. It performs the following tasks:
- Routes pages.
- Delays, queues and sorts delayed pages based on priority and zone availability.
- Plays and routes prerecorded messages.
- Queues and sorts message playback based on priority and zone availability.
- Mixes pages and messages with background music (BGM), including ducking.
- Routes BGM.
- Controls the Gain and Mute for Pages, Messages, and BGM.
The PA Router accepts audio files for preambles, messages and BGM. One track is supported (additional tracks are ignored). The files can be loaded onto the Core using the Q-SYS Core Manager > Files page.
The files for preambles and messages are selected in the Q-SYS Administrator > Commands tab. The files for BGM are selected in the Q-SYS Designer Schematic.

Refer to the Core-to-Core Paging topic for details.
Inputs
Station Audio - One input for each Page Station as defined in the PA Router property Station Count. The audio source can be the microphone or the Aux input on the physical Page Station, any audio source in Q-SYS Designer (Audio Player, Mic/Line Input card, and so on)
Station Control - One input for each Page Station as defined in the PA Router property Station Count. Connect the Station Control from the Page Station (virtual or proxy) to this input on the PA Router.
BGM Input - Connect the background music source here. The number of inputs is set in the PA Router Properties BGM Input Count.
Outputs
Zone Audio - One output for each Page Zone defined in the PA Router Properties Zone Count.
Note: You must have at least one Page Station and only one PA Router in your design to set up a Paging System. If you have more than one PA Router in your design it will not compile.

Note: The number of signal pins is variable and set in the component's Station Count and Zone Count Property.
Input Pins
Station
Page Station Control pins carry control type signals unique to a Q-SYS Paging System. They are found on Page Station Components (proxies for the hardware), Virtual Page Station Components, and the PA Router to which both of the Page Station Components connect. The pin is represented by a down-pointing triangle.
By default, the PA Router component is set to 8 Stations and 8 Zones, which provides 8 inputs and 8 outputs. Additionally, you can choose between 1 and 256 inputs and outputs.
Output Pins
Zones
Audio signal pins are represented by a () circle, and traditional wiring is represented by a thin black line. You can use Signal Names on audio signal pins.
By default, the PA Router component is set to 8 Stations and 8 Zones, which provides 8 inputs and 8 outputs. Additionally, you can choose between 1 and 256 inputs and outputs.

In this example, we have two microphones from two Page Stations feeding into a PA Router.

Tip: For additional properties not listed, refer to the Properties Panel help topic for more information.
PA Router Properties
Station Count
Sets the number of Page Stations you have in your Q-SYS Design. The Page Stations can be the Virtual Page Station or the hardware proxy. The number of stations you define is available for configuration in the Administrator.
Zone Count
Sets the number of PA Zones for your paging system.
The number of Zones you define, is available in the PA Router Control Panel where you can select the BGM for each Zone.
The number of Zones is also available for configuration in the Administrator.
BGM Input Per Zone
Sets a single BGM input assigned for each PA Zone.
BGM Input Count
Sets the number of BGM inputs you want for your paging system. You can assign any one of the BGM inputs to one or more PA Zones.
Note: This setting is only available when BGM Input Per Zone is set to No.
BGM Selector Controls
Sets the selector type for choosing the BGM input source per zone.
Remote Sources Count
Sets the number of external PA Router sources to the current Core PA Router.
Remote Destination Count
Sets the number of outputs the current Core PA Router can send to other external PA Routers
Remote Source
Name
Sets the name for the assigned Remote Source
Type
Sets whether the assigned source is via a patched audio path, or Q-LAN stream.
Channel Count
Sets the number of audio channels for the assigned source.
Q-LAN Redundant
Enable this property if the Q-SYS Core is connected to both LAN A and LAN B for network redundancy.
Note: For the Q-SYS Core 110f and 110c, each Q-LAN Receiver with this property enabled consumes two streams instead of one. Use File > Check Design to see your design's Network Audio Input count.
Q-LAN Verbose
This property currently has no effect.
Remote Destination
Name
Sets the name for the assigned Remote Destination
Type
Sets whether the assigned destination is via a patched audio path, or Q-LAN stream.
Channel Count
Sets the number of audio channels for the assigned destination.
Q-LAN Redundant
Enable this property if the Q-SYS Core is connected to both LAN A and LAN B for network redundancy.
Note: For the Q-SYS Core 110f and 110c, each Q-LAN Receiver with this property enabled consumes two streams instead of one. Use File > Check Design to see your design's Network Audio Input count.
Q-LAN Verbose
This property currently has no effect.


Zone 1 - n

Name
The name as specified in PA Zones (Administrator).
Mute
Mutes all signals to the Zone. One Mute button for each Zone.
Gain (dB)
Sets the gain for all signals to the Zone. You can enter the value using your keyboard, or change it by selecting the field and dragging the mouse.
Squelch Priority
Allows you to silence pages and messages at and below the Priority level selected.
You can create a Control Command and Schedule it to change the Squelch Priority to prevent pages and messages from being played in certain zones at certain times.
Buffer
Displays the amount of PA Router audio RAM in use.
Note: You may notice the PA Router buffer percentage increases each time a new message is sent to be played. This behavior is expected. There is one hour of buffering allocated in 1 second increments available for delayed pages, messages, and preambles. Pages are discarded immediately after playback (and optionally archived). Messages and preambles will remain cached in buffers in case they are played again, but they will be discarded on a last used basis when more space is needed.

Squelch
LED indicating that the associated PA Zone is being squelched.
Active
LED indicating that the PA Zone associated with the LED is Active (illuminated) or not.

BGM Ducker Attack (seconds)
The Attack is the time it takes the BGM to fall to 63% of the Depth level when the a Page or Message is played.
Use this control to provide a smooth transition from the BGM audio to the Page or Message audio.
BGM Ducker Depth (dB)
The Depth sets the amount of gain applied to the BGM Input channels when the BGM Ducker is activated. The Page or Message is mixed with the BGM, so the Depth setting controls how much of the BGM is heard in the output. Setting the Depth to 60 dB of attenuation essentially mutes all BGM channels used by the Page or Message.
BGM Ducker Release (seconds)
The Release Time is the time it takes the BGM channel outputs to return to 63% of their normal level when the BGM Ducker is deactivated - the Page or Message ends.
Use this control to provide a smooth transition from the Page or Message audio back to the BGM channel audio.

Note: Remote Source tab only appears in the Controls when Remote Sources Count is set to a non-zero number and the Type property of the Source is set to Q-LAN.
