E to E Timed Outputs
In some applications, you may want to precisely switch an output from a live
video feed to playback of recorded material. Since the live input will be delayed
as it passes through the Profile unit, you must set a corresponding delay on the
playback. The E to E Timed Output option sets a 16-line delay on all the system
outputs, allowing a zero-timed input to be exactly timed with a play to air
signal. To set all your Profile unit output for E to E operations:
1. Choose Options | System Timing or click the System Timing button on the
toolbar. The System Timing dialog box appears.
