Multi-Level Switching

There are two modes of multi-Level switching: All-Level Takes and Break-
away Takes. All-Level Takes switch the same input number on all Levels,
to the controlled Destination, as shown in

Figure 2

Figure 2. Traditional All-Level Take

A Breakaway Take is performed by accessing the control Levels of a Desti-
nation individually and selecting a different Source on at least one Level
other than that selected on the others. Breakaways allow a Destination to
selectively utilize video and audio from different Sources.
