Keyer Delegation Buttons
The keyer delegation buttons select which of the keyers is being
changed. In normal mode, the Keyer Subpanel, located in each
M/E row, can be delegated between Key 1 and Key 2.
In layered mode, four keyers are available –
Key 1, Key 2, Background B, and Background
A.
KEY ON Indicator
The key oN indicator lamp lights when the delegated keyer is in
use. This indicator is a logical AND of the ON indicator in the
transition subpanel and the keyer delegation selection.
Key Type Buttons
The second row of buttons from the
bottom of each keyer subpanel selects
one of five keyer modes.
Pressing the LINEAR KEY button selects a linear key with a gain
fixed at unity, clip fixed at 50%, and no S-shaping. The LINEAR
KEY
button lamp (only) is illuminated when linear key is selected
on the delegated keyer.
If a linear key is desired, but the key signal is not at the correct
level, adjustments can be made with the (CLIP) and (GAIN) knobs.
(CLIP) adjusts the offset of the key signal (over a small range) in
linear key mode. (GAIN) adjusts the amplitude of the key signal
(over a small range).
