Tip
The switcher allows you to perform a split key on any DSK. This
function holds the DSK crosspoint’s alpha signal, and assigns a new
video source to fill the hole. To perform a DSK split key, hold down
the desired DSK crosspoint, then press a crosspoint on any bus
except
the Preset Bus .
Operating
Tip
Pressing
KEY2
instead of
KEY1
would assign the Key bus to Key 2 .
Note If, after setting up the split, you select another Key type, the split is
released and you must set it up again if desired. Pressing
AUTO
SELECT again does not re-establish the split.
