Delay Output
Because the ARC130S contains a synchroniser,
the through delay depends upon the setting of
vertical genlock timing.
If the input and output video are co-timed, then the
delay through the ARC130S is four fields (80 ms
for 625 line systems and 66.7 ms for 525 line
systems). If the input and output video are not co-
timed then the range of delay through the ARC is
3.5 to 4.5 fields.
The delay pulse output from the ARC130S
accurately represents the delay through the unit.
The pulse is high for a period equal to the delay
through the ARC. It can be connected to a Snell
and Wilcox audio delay module to automatically set
a compensating audio delay.
If the ARC130S is put into Bypass mode or, field
pairing mode, then the nominal delay remains at
four fields. However because the unit acts as a
frame synchroniser in these modes, the delay
range of the unit is now increased to between 3
and 5 fields.
