3.5.1 M/E MODES
The basic operation mode of keyers can be selected with the buttons M/E1 Mode,
M/E2 Mode and M/E3 Mode.
Layered Press the associated function button to switch over to Layer mode for the individual
mixing levels M/Ex. In Layer mode, background A and background B become inde-
pendent from each other with each background bus functioning as a key bus. Each
signal is limited with a key pattern. The background is black.
The PVW path is used to create a B/W key transition signal which unites all cur-
rently active layers. If, for instance, in the DSK a mixing level in Layer mode is
selected as a fill signal, this key signal will automatically be added to the key transi-
tion signal. The keyer should be switched to Linear.
Note for using the Layer mode:

ating functions:

els M/Ex. In this mode, the Mask Bus button in the respective keyers menu is dis-
abled.
