9.3.4 An example of setting offsets

A practical example of setting offsets is given
here.
The master DA-98 contains the tape with the dia-
log and reference tracks from the video worktape.
Another DA-98 (the slave) has a tape with some
tracks containing video backing music.It is neces-

when the master is played, the music tracks will
start at the correct time relative to the dialog and
reference tracks.
