– Video Switching
Main Source and Sub Source Rows
The Main Source Row of buttons is the active channel, this is the Live output. The active channel will appear as the
Program Output (PGM). You can switch or CUT from one source to another directly on the Main Source Row. You
will see the PGM Output change as you press different keys along this row of buttons.
The Sub Source Row is the Cued channel; this channel will appear in the PST or Preview window. The Sub Source
selection determines which input will be transitioned to when using any of the transition controls.
N.B. The keys on the Main and Sub Source Rails will be inactive while the T-Bar is active. Only when the T-
Bar is fully up or fully down will the keys respond.
