Control Panel Controls
Control Panel ME Partition Delegation
When an ME has been split, the Pri and Sec delegation buttons on that ME
are activated.
Pri and Sec Delegation Buttons
The Pri and Sec buttons delegate the source selection buses and the Transi-
tion area and Local E-MEM area of that ME, to the selected partition.
Pressing one of the
Pri and Sec buttons deselects the other. At least one par-
tition is always selected on a split ME.
Delegating Both Partitions
Holding down one of the Pri and Sec buttons and pressing the other dele-
gates both partitions. When the panel is delegated to both partitions, the
E-MEM and Transition areas control both partitions simultaneously. Also,
the button tally indicators in the Transition area and the transition pattern
shape displayed in the ME Status display reports information for only the
Primary partition.
Source Selection
When an ME is split and its Control Panel controls are delegated to only the
Secondary partition, the alternate buses for that ME are reversed. Keyer 3
and Keyer 4 sources are selected on the keyer buses and Util 1 and Util 2
sources are selected on the background buses by default. Holding down the
delegation buttons allows source selection on the other Keyer 1, Keyer 2,
Bkgd A and Bkgd B buses. This works well for the typical situation where
an ME is split into equal partitions, with Keyer 1 and 2 assigned to the
Primary partition and Keyer 3 and 4 assigned to the Secondary partition.
If both partitions are delegated, source selection behaves the same as when
only the Primary partition has been delegated.
ME Partition Preview
Preview outputs are available for both partitions of a Split ME. The ___ MxpA
output of each bank is used for the Primary partition preview, and the ___
Mxp2 output is used for the Secondary partition preview. These preview
signals can be mapped to output connectors with the Output Assignments
menu, accessed by touching
Eng Setup , Outputs .
You can preview ME primary and secondary ME partitions on switched
preview using the System Bar. Press the
Sw PVW button and select an ME for
primary, select the ALT button (next to Sw PVW) to see the secondary.
