Auto Delegation

Panel Delegation

Some of the controls on the Model 2200 Switcher are delegated to
other controls under conditional control of the operator or system.
This feature is called “auto delegation.” The effect of auto
delegation is that pressing a button on one subpanel may activate
the controls on another subpanel of the control panel. For
example, the single chroma keyer subpanel is used for controlling
all chroma keyers, and is activated by pressing the CHR KEY
button on either of the M/E Keyer subpanels. Auto delegation is
normally on, but can be turned off via the User Preferences menu.
Table 2-1 shows some of the delegations present in the Model 2200
Switcher.
