Key Buses
The Key buses in each M/E and the PGM/PST are delegated to the avail-
able keyers by the Key Bus Delegate subpanels in each section of the panel
as described below.
When a Keyer is selected in a subpanel, the currently selected source for
that Keyer will light on the Key bus. Selecting a different crosspoint will
change the key selection.
Selecting the
Util
button delegates the Key bus to be the Utility bus source
selector. A crosspoint selected on the Utility bus can be used as a key signal.
Selecting the
Macro
button delegates the Key bus to be a set of macro func-
tion buttons.
The Key source selector buses in M/E 1 and 2 are delegated six ways to
Key 1, Key 2, Key 3, Key 4, Utility, and Macro. Delegation of the Key bus is
assigned with the M/E Key Delegate Bus subpanel (
)
in each M/E.

Within this delegation, the row of buttons can be unshifted and shifted in
the same manner as the Background buses. In addition, the cut and fill
signals assigned to a key crosspoint in button mapping can also be split
using the

The Key Bus Delegate subpanel in the PGM/PST key row is delegated four
