Multi−Source, One−take Splits
The CP 3830 will allow operators to perform complex split switches using multiple sources on levels not defined for all
sources, similar to a salvo switch to a single destination. For example, assume the user has defined Camera−1 with Video and
TimeCode only levels. However, he or she desires CD−1 for audio. To perform this switch in one take:
1. Select all levels to be switched.
In this example, the operator would press the buttons corresponding to Video, Left, Right, and TimeCode. The buttons
will light in “high” green, indicating they are selected.
2. Select the first source.
In this example, Camera−1 would be selected.
3. Deselect the levels that apply to the second source.
In this example, Left and Right.
4. Select the second source.
In this example, CD−1 This source will automatically be assigned to the remaining levels, Left and Right audio.
5. Press TAKE.
