With the Split button off, the mixer's layers are ganged together, and two mutually-
exclusive sub-modes now determine the mixer's function: Mix Source and Swap .

One or two PIPs
One or two Keys
One PIP and one Key
With Mix Source mode enabled, both of the mixer's PIPs or Keys are perfectly
co-located. Layer A and Layer B are exactly the same size — in exactly the same
position — with exactly the same border and shadow. This mode is ideal for
transitioning images inside a static PIP. Even though two identical PIPs are used,
they visually appear as one.
With Swap mode enabled, both of the mixer's PIPs or Keys can be located
independently, with different positions, sizes, borders and shadows. Layer A and
Layer B can be positioned and sized as desired — but only one can be on
Program at a time.
With Toggle mode enabled, sources toggle back and forth with each transition.
When a PIP or Key source is selected in Preview and a transition is performed,
the Program source "flip-flops" to Preview. Subsequent transitions simply
alternate between sources. Any new source can be selected in Preview, and as
long as Toggle is on, the last two selected sources will alternate.
With Toggle off, the source selected in Preview stays in Preview, once the
transition is complete. In this mode, you must change Preview sources manually.
In Mix Mode , there is always a layer available In Preview for a new source to be
selected and taken to Program.
Four transition combinations are possible:
~
Mix Source with Toggle On
~
Mix Source with Toggle Off
~
Swap with Toggle On
~
Swap with Toggle Off
