Grass Valley iTX System v.2.6 - Manual (Page 206)

Configuring the audio output for a playout channel
Compatibility of source tracks
For iTX to be able to use a particular source track for playout, the track must be: either of the
same audio type as the required output track; or of another audio type that makes the source
track compatible with the output track.
A compatible source track is one that iTX can use to produce the output track. In the table
below, we list some compatible source track types for possible output types. The table relates
to primary events only.
