Going back to the VTR 1 example, each of the 3 routing switcher outputs (SDI, AES/EBU, and analog
audio) could be assigned to a different level, under the VTR001 label.
Whenever destination VTR001 was selected all 3 crosspoints in the 3 different routing switchers would
switch together. This approach is often the simpler approach to implement, and understand, but it can
limit future flexibility in operation, as we will see.
