Level buttons
Breakaways can be accomplished either by presetting the levels to switch, and then selecting a source, or by selecting a source
and then deselecting unwanted levels.
Breakaways can be disabled on the CP Level Set table by setting the Break Flag for each level to ‘N.’ (See page 5−58.)
Level Preset Method
1. Press the Level button corresponding to the desired level.
The level mnemonic appears in the Preset window and the button will illuminate in “high” green with the current status
of that level in the current window. The level may be toggled off by selecting it again. The current window will be blank
if there is no status for that level.
Pressing CLEAR will cancel the operation.
2. Select a source.
Note: If the level window goes blank, the source may not exist on that level (e.g., audio from a camera).
3. Press TAKE (or, on a CP 3830P, PRESET TAKE, TAKE).
The source will switch only on the preset levels, while the non−selected levels will remain at the previously selected
source.
The Current window will display the defined mnemonic for the first level.
To check the status of individual levels, see Status Mode on page 6−96.
