Mix/Effects Banks
CHR (chroma key): A particular hue
(usually blue) in the key source signal
is used to determine the hole to be cut
in the background.
You can use the following signals as
chroma key signals (foreground).
• In a D2 system: an analog
component signal.
• In a D1 system: an analog
component signal, or a primary
input.
PTN (pattern): This uses a wipe pattern
(generated by the dedicated wipe
generators on each M/E bank) to cut
the hole in the background and insert
the key fill. As for a wipe, you can
also apply a variety of modifications
depending on the pattern, but the wipe
direction and edge modifiers are not
available.
4 KEY INV (invert) button
To invert the sense of the key source
signal. Instead of the normal black titling
on a white background, you can use this
function to provide a key source with
white titling on a black background.
You can also use this button as the
programmable button by assigning other
functions.
For more details, see "Changing switcher
functions (OPERATION MODE menu)"

5 Key insert/remove buttons
Use these buttons to insert and remove
keys 1 and 2.
KEY ON: These buttons
(instantaneously) cut the respective
keys in, or when the key is already
inserted, cut it out.
When the corresponding key is
inserted in the output of this M/E
bank, these buttons light amber, and
when it is present in the final program
output from the switcher these buttons
light red.
KEY MIX: These buttons fade the
respective keys in, or when the key is
already inserted, fade it out.
During a fade in or fade out, when key
1 or key 2 is present in the output of
this M/E bank, the corresponding
KEY ON button lights amber; when
the key is present in the final program
output from the switcher the button
lights red.
The durations for a fade in or fade out
can be set independently for key 1 and
key 2, to be different from the
transition duration of an M/E
transition.
