5.4 3403 SDI Frame store synchroniser
The 3403 is an advanced SDI frame store synchroniser capable of synchronising
asynchronous feeds or providing a fixed delay. When used with the TX Series master control
systems the unit is used to provide a fixed 1 frame delay compensating for the delay
introduced by the system DVE.
Configuration of the module is from a card edge switch, shown in the diagram below and,
detailed in the following tables.

Delay/ Offset controls
In delay mode (switch 2 ON), the rotary controls alter the delay with respect to the input. Full
details of these switches can be found in the 3403 handbook. When used with the TX series
mixer these switches need to be set as defined in the following table to provide a delay that
matches the delay through the 3426 DVE.
