Key Bus
Each MLE includes a Key Bus (a sample of which is shown below):
Synergy 3 — Key Bus Indicators
1. Key Bus
The Key Bus allows you to make key and fill selections on both MLE keyers — Key 1
and Key 2 (for the upstream MLEs), or DSK 1 and DSK 2 (for the Program/Preset
MLE). Even though the Key Bus buttons are shared between the two keyers, each keyer
can have its own independent key and fill selections.
Please note:
• Pressing any button in a keyer switches control of the Key Bus to that keyer .
• When the Key Bus is assigned to Key 1, changing a button on the bus has no effect
on Key 2. Similarly, when the bus is assigned to Key 2, changing a button has no
effect on Key 1.
• When a keyer has control of the bus, its crosspoint selection will be brightly lit on
the bus row. The crosspoint selection for the other bus (the one that does not have
control) will be dimly lit.
2. Key Control LEDs
The two Key Control LEDs indicate which Keyer has control of the Key Bus buttons.
3. Key Bus On Air LED
The Key Bus ON AIR LED indicates, when lit, that the video feeding that Keyer is on
air (and contributing to the switcher’s main program output). When lit, the source
selected on that bus will be tallied.

Note
If you press a Key crosspoint button that is assigned to an external
device, the device control menu will be displayed. Pressing the button
again will cycle through the device menus and the
Key Type Menu .
