Columns in the first set of control groups are numbered as Input 1- 16. Each of these can be assigned to any available audio source – whether analog (line level) sound supplied to rear panel connectors, SDI embedded audio from one of the four SDI inputs, available NDI source, or other system audio source (including network audio sources like Audinate’s Dante™, with appropriate drivers.

You may choose to think of these audio sources as being associated with the same-numbered video inputs in the nearby rows on the rear connector panel. This linkage, though the default, is not strictly enforced, however. You can connect directly to any external audio source in Advanced Configuration. Also, for reasons of your own, you may well prefer to treat various audio sources as independent of the nominally associated video input. The Follow (audio follows video) features play an important role in this context. See the sub-heading Follow Program Video in Advanced Configuration.
