Each input button of the CP 3832 / 3864 can be assigned to a specific source using a CP Input set (page 5−74.) The name of
this set, and the name of the destination to be controlled, is entered on the MPK Devices table (page 5−110 and following).
To verify destination − for the CP 3832, press MENU. The destination will be shown in the Preset window. Then press
CLEAR. On the CP 3864, the destination is always shown in the “Destination” window.
Audio−follow−video switching - (PRESET off.) When one of the source buttons is pressed, a Take* command is issued to
all levels of the switcher matrix (pressing the TAKE key is not necessary). A status* signal is then returned to the control panel;
this confirms the action by lighting the input button that was pressed and displaying the name of the input in the “Current”
window.
To verify a source before switching (PRESET mode) − To examine the mnemonic of a source in the Preset window before
a Take, the PRESET button should be flashing red or green (press if needed). Select the desired source and check the mne-
monic in the Preset window. Then press TAKE.
Breakaway switching − single level Take − (PRESET Off, or, blinking green.) To switch only a specific switcher level, the
level is defined by first pressing the LEVEL button; the name of the first level will be displayed in the “Preset” window. To
advance to the next level, press LEVEL again. The TAKE command to the switcher will be executed when an input button
is pressed.
If the switch was made on level 1 (usually video) the new input will be displayed in the Current window. If the switch was
made on another level, use the LEVEL button to return to that level; the new input will be displayed in the Current window.
(To turn off the LEVEL button, press CLEAR.) Notice that only the button for the lowest level will illuminate.
Breakaway switching − multi−level Take − To switch different sources to different levels with a single Take command, press
PRESET (so that the button is flashing red). Then press the LEVEL button. The name of the first level will be displayed in
the Preset window. Advance to the desired level by pressing LEVEL; then select an input for that level. Press LEVEL to select
another level; select the next input, etc. When all selections have been made, press TAKE.
The input for level 1 will be displayed in the Current window. To check the status of another level, use the LEVEL button
to return to that level; the new input will be displayed in the Current window. (To turn off the LEVEL button, press CLEAR.)
Notice that only the button for the lowest level will illuminate.
