The growth of 5.1 and 7.1 audio has increased the number of audio channels that must be managed in a production. FS3 accepts embedded SDI audio on all four SDI inputs (two coax and two optional fiber), and has an internal 64x64 audio matrix that allows routing of all embedded audio channels.
Front Panel Control The FS3 front panel offers the most direct control, ideal for use in machine rooms or wherever quick changes and status checks must be made. The buttons and knobs control menus in the display, allowing you to fully configure the system according to your purposes.
• Single Output SC connector • Dual Input LC connectors • Dual Output LC connectors FS3’s Fiber I/O supports the 3G/HD/SD SDI protocol. Only AJA modules are supported; use of other manufacturers’ modules is not supported and may void the warranty.
Proc Amp controls and RGB color correction. Audio Processor The FS3 can accept and route any embedded audio input to the logical SDI1 thru SDI4 outputs. Audio on SDI1 thru SDI4 outputs is duplicated on SDI5 thru SDI8 and Fiber1 thru Fiber4 outputs.
That Mapped Output Format is recalled if the frame rate selection is changed. Forty different presets are available that can be used to restore the FS3 to a previous state. Many parameters can be individually reset to factory values using individual menus, or the entire FS3 can be reset to defaults (with the PRESET, Factory Preset menu).
ALARM Alphanumeric Display The FS3’s control system is designed to be quick and easy to use. The four-line alphanumeric display shows menus that are numbered and grouped by function. The menu groups are easily accessed using pushbuttons which correspond one- to-one with the groups (one button per menu group).

Alarm Suppress parameters.) Incompatibility Alarms The FS3 produces signal incompatibility alarms for a number of reasons. For example, incompatible conversion alarms can occur because the FS3 cannot convert between frame rate families (59.94/29.97/23.98, or 50/25, or 24).
Using the REMOTE menu group, you can program the actions of the GPI inputs and outputs individually. Contact closures on the inputs can trigger a wide variety of FS3 functions. Alarms or loss of video can trigger the GPI outputs. 10/100/1000 LAN This RJ-45 connector provides an Ethernet 10/100/1000 port for connection directly to a computer or to a LAN through an Ethernet hub or switch.

Chapter 3 – Installation & Configuration Installation Overview The installation and set up of an FS3 is very simple. Plug both AC supply cords into AC mains power (separate branch circuits for redundancy), connect the LAN connector to a LAN, WAN or local computer with a web-browser, and then connect source and destination video and audio equipment.
If you find shipping damage, contact your AJA dealer or distributor for details on how to have your FS3 repaired or replaced. NOTE: Save packing materials and the shipping box. If your FS3 ever requires service or you move your system, use the packaging materials and box for safe shipment.
FS3 units. Note the location of cooling vents on all equipment next to the FS3 and ensure none are obstructed. NOTE: FS3 units can be stacked vertically without limit as long as there is an adequate supply of cool air around the FS3 vents.
Networking Using DHCP or Default Static IP The FS3 factory default configuration automatically looks for a DHCP server to issue an IP address. If your network includes a DHCP server, plug the FS3 into the network and connect with the unit as follows: 1.
If the FS3 cannot get an address from the network DHCP server, the FS3 will automatically use a preset factory static IP address of 192.168.0.2. You can access the FS3 using the default static address as follows: 1. Set your computer’s IP address to whatever address you prefer in the 192.168.0 (class C) network.
Using Ping to Test the Network Connection If you have connected the FS3 to a computer and set up the IP address and still do not see the FS3 screens in your browser, you can ping the network to verify the connection.
To control the FS3 from a web browser on a network attached computer, enter the FS3 IP address as a URL in the browser. For example, if the FS3 IP address were “90.0.6.31”, you would then type into the web browser: http://90.0.6.31. This topic is explained in greater detail in Chapter 5: Browser Remote Control.
FS3 web screens. If the FS3 did not update successfully, run through the update steps again. NOTE: The configuration of the FS3 prior to the upgrade is preserved. The unit returns to service exactly as it was before the upgrade.
"GPI Pinouts" on page 93 for information on how to wire the GPI connector to work with external devices that you want to use to control the FS3 or that you want the FS3 to control. Stand Alone Tests The stand alone tests can be performed without a computer, using the FS3 front panel controls and rear connections.

SNMP, alarm, and screen saver configurations. 1 System Name This parameter defines a unique name for the FS3. This same name is used both when displaying systems via the web interface and when displaying the FS3’s screen saver.
Without a properly configured default gateway (whether you have a router/ gateway or not), the FS3 will be unable to see other FS units on the network, although you may still be able to control this unit via a web browser. Also, without a proper gateway defined, the discovery feature on the Network web page will fail to list other FS units on the network.
Alarm will not be triggered by a format incompatibility. 7 Reference Alarm This parameter controls how the FS3 responds when the Video Processors has a format that is incompatible with the Reference video signal. When set to NORMAL, the alarm triggers if the Reference signal is not detected or is incompatible with the processor format.
The PRESET Menu Group provides the means of saving, editing the names of, and loading FS3 presets. A preset is a set of all System, Video, Audio, and most Config parameters as they were set at the time the preset was stored.
1. 1 -1.40 Presets #1-#40 These parameters let you recall, edit the name of, and store an FS3 preset configuration for the selected storage register. Forty storage registers are available. Preset #1–#40 Shows the currently selected preset register number. Turn SELECT choose the desired register.
2 physical input. Choosing Auto Detect or Dual Stream in SDI1 3G Detect does not switch away from the physical input. In the Dual Stream setting, the FS3 assumes both channels of Dual Stream 3G video are muxed onto a single wire at the SDI1 input. The SDI 2 video signal is then taken internally from the SDI 1 Stream 2 signal instead of the SDI2 In connector.
Input Use the input signal as the genlock source. Free run Free run mode (FS3 syncs to its own timebase, not locked to an external source). 6 Output Frame Rates This parameter selects the HD video frame rate associated with the video standard.
The output is the test pattern generator. NOTE: Normal output can be a version of its currently selected input, a Sidebar or Letterbox display, a Freeze of last good video, or Black, depending on the current configuration. FS3 Frame Synchronizer/Converter v1.1r1 www.aja.com...

AUDIO PROC Menu Group The following descriptions explain the Audio Proc Menu Groups, which allows you to make adjustments to the audio inputs to the FS3 audio processor, and to control audio routing. The Audio Proc Menus are formatted as follows...
• Each of the individual eight SDI1 audio input channel pair delay values are applied to the input delay of each channel pair. • The range of delay is -16ms (-768 samples) to +256ms (+12288 samples). 48 samples = 1 millisecond. FS3 Frame Synchronizer/Converter v1.1r1 www.aja.com...
When set to 5.1 or 7.1 Channel Mode, additional menus follow that are used to select the source of the incoming multi-channel audio, adjust the levels of each of the incoming channels to the Left and Right outputs, and adjust the gain of the Left and Right output channels. FS3 Frame Synchronizer/Converter v1.1r1 www.aja.com...
Page 66
Multi-channel audio, typically embedded in an SDI signal, can be passed through the FS3 converter unchanged. The multi-channel sound can also be mixed down to stereo, using the two Mix Down Modules built into the FS3 audio processor. The default 5.1 to 2 ch. mix-down equation is:...
No embedded audio (HANC) is generated. About Audio Routing The SDI1 through SDI4 Audio Output menu titles refer to portions of the FS3 SDI embedded audio output signal (embedded audio groups), not the SDI 1-4 BNC connectors. The selected input source audio is routed to all the corresponding FS3 output connectors.
Page 68
4K and UltraHD video can carry four groups of 16 channels (64 total) of embedded audio. The FS3 can receive up to 64 audio channels, 16 on each input connector, and can route these incoming audio channels to the embedded audio outputs, via the internal embedded audio groups, called SDI1-SDI4.
Select the source to route to the selected output from the following through sources: SDI1 Output Ch 16 -SDI1 Ch1 - Ch16 -SDI2 Ch1 - Ch16 -Fiber1 Ch1 - Ch16 -Fiber2 Ch1 - Ch16 -Mix Down L - R -Sig Gen 1kHz -Sig Gen 400Hz -Mute FS3 Frame Synchronizer/Converter v1.1r1 www.aja.com...
"17.0 SDI1 Audio Output" on page 69 21 Global Audio Output This parameter allows routing the same source or set of sources to all the FS3 outputs. The rules used for Audio Out apply if the number of outputs do not match the number of inputs.
