Video output (encoder output) signal adjustments
After this system has been connected, the video output signal (ENCODER OUT) must be
adjusted if AB roll editing (editing using two source machines) using an editor, for instance, is
to be error-free and accurate. (This adjustment must be repeated when one of the
connecting cables has been replaced and whenever the connections are changed.)
The adjustment procedure using this unit is outlined below.
1
Check the connections. (See page 22.)
2
Set the REMOTE/LOCAL switch @2 on the front panel bottom section to the adjustment
position (LOCAL).
REMOTE: For adjusting the video output signals using an external encoder remote
controller.
LOCAL: For adjusting the video output signals using this unit.
