■ Press the TAKE key to complete destination selection
The level displays will indicate the sources currently selected
(status) on the destination you have chosen. No change has yet
been made; you are simply being informed of the current
configuration. LEDs in the LEVEL buttons beneath any protected
source/destination configurations will flash to indicate that
protect is active.
Presetting a destination, rather than permitting a blind take,
ensures that you can view current status and accurately predict
the effects of a take. You will know before performing a take which
crosspoints are protected and which levels are responding.
Presetting Sources
Sources on the various levels may be preset one-at-a-time for
breakaway operation or they may be preset as a group. (If the
panel is set to All Levels using the rear-panel switch, it will only
preset all levels of a source as a group.)
Before you can preset a source, the panel must be displaying the
status of the intended destination.
To preset levels selectively:
■ Press the LEVEL button under the selected preset
display(s)
The display will load with dashes awaiting entry.
■ Enter the number of the desired source using the numeric
buttons
The number will be loaded into the selected preset display(s) and
will flash to indicate it may be edited without disturbing current
selections. To edit, you may enter a new number (overflowing the
display) or you may press the CLEAR button and begin again.
Pressing another LEVEL button will cause the just-entered
number to flash slowly, indicating that it is a non-editable preset.
Should you wish to return and re-edit, simply press the associated
LEVEL button.
