The AB Mixer is an integral 2 input video switcher, which provides the
background video source to the program keyers. The mixer can be configured
for both cut and variable fade transitions from this menu. Using the front
panel control keys (⊳ ) display the transition type you wish to select then
press the enter key.
Note Pressing the enter key will activate the transition.
A CUT transition is an instant switch to the selected source. This is achieved
between frames in the vertical interval so the active picture is allowed to
finish before the new data is transmitted.
A FADE transition is the gradual process of switching to the selected source
with rates adjustable between 1 and 999 fields (16.65 seconds @ 60Hz)
The front panel display will identify the background video source. Either A
or B will appear on the top line of the display depending on which is active.
