The next level of complexity is
a vertical delay cluster
where a video unit can have up to eight audio delays
tracking - of the same or different types.

From one to eight audio delay products can be connected via RollCall™ to a single frame synchronizer, for
example. If the synchronizer delay changes, then however many audio delays are connected will track the
delay. The audio delays can also have a manual delay which will be added to the RollTrack delay.
The next level of complexity is
a horizontal delay cluster
where an audio delay can track up to four video units.
