AJA FS1 - Manual (Page 22)

Notes:
1. In the case of 1080pSF/23.98 input—and when 1080i59.94 (or 525) is
selected as an output format, the FS1 automatically adds 3:2 pulldown to get
the correct frame rate. Similarly, in the case of 1080pSF/24 input, FS1
automatically adds 3:2 pulldown to get the correct frame rate.
2. When passing 24 or 60 framerate video, the standard definition outputs will
not output valid video (the FS1 is not a framerate converter).
Rear Panel
About Inputs and
Outputs The function of the FS1 Inputs and Outputs depend on the operational mode.
Operation is simple in steps: first select an output format, and then select the
desired input. All outputs are active all the time. By selecting an output format first
and then the input source, the FS1 can automatically put in place any conversion
required (up/down/cross). Audio embedding/disembedding is also automatic,
following any parameter settings you’ve selected for your application. For example,
even though the input selected might be HD-SDI with embedded audio, the analog
audio output connectors will output proper analog audio that has been
disembedded from the serial digital stream.
Please study Chapter 4 Parameter Menus, for a full understanding of all the FS1
settings possible.
Connectors
Connectors on the rear panel are arranged in groups for easy installation and
maintenance. Connectors provided are:
• 2 AC power connectors, each 3 pin (with Ground), one for each independent
power supply. Each power supply is autosensing from 100 to 240VAC at 50/
60Hz. Only one has to be connected for FS1 operation, but redundant
operation can only be ensured if both connectors are plugged into mains
power.
• 8 channels AES/EBU digital audio in and out, two pairs per BNC.
