Multi Function Control
Key 1...6
These buttons delegate the Keyers Panel and indicate which keyer is cur-
rently delegated to the Keyers Panel.
Due to the Auto delegation
the keyers panel is automatically delegated to the
appropriate keyer when it makes sense.
When Auto Menu
is enabled, the menu display of the attached side panel will
switch to the appropriate Key Menu
and sub-menu. Parameter adjustment is
performed by the menu digipots.
Key Sources
Matte Fill
The Matt button serves to select a color matte as a fill signal for the respec-
tive key in place of the fill bus signal.
Self - Couple - Split Key Buttons
When the Miscellaneous Bus is delegated to a keyer, a source selection
always selects the Fill signal for the corresponding keyer.
The Self - Coup and Splt buttons define the way in which the key signal is
selected.
• If Self is selected, the selected fill signal is also used as key signal.
• If Splt is active, the key and fill sources can be selected separately.
• If Coup is active, the operator selects a Key Fill source on the Key Buses
row, and the switcher automatically selects the Key Source signal using
the Coupled Key table.

The Coupled Key table is defined in the menu. 
The default table entry for Coupled Key is White . For DVEs, character
generators, graphics, etc., the input where the Key signal from such an
image source is connected should be coupled to the input where the
video signal is connected.
Key Types
Add Key
The Add button serves to select the additive key mode. In this mode, an
external unit (for example, modern caption generators, paint systems) gen-
erates and supplies the key signal and the associated fill signal.
The background signal is multiplied with the key control signal and added
to the supplied fill signal. This mode ensures that the supplied fill signal is
not influenced and that all details contained in it are reproduced true to the
original.
