the system can be pre-set with up
to five external sync sources, plus
internal, such that if the 1st source
fails, it will automatically switch
to the 2nd, and so on. one of the
external sources can be Video, (Pal
or ntSC). ttl wordclock is another
possible external source.
AES inputs on the console can also be
used as an external source. Please note
that the facility for locking to external
AES sources is restricted to the first six
SynCHrOnISatIOn
inputs of each AES card in the console.
When using a digital input or wordclock
as a source, the system will tolerate
a variation of up to +/- 100 Hz in the
frequency of the source.
Assigning Synchronisation Sources
Synchronisation sources are assigned
by selecting an available source from the
list on the left side of the screen, then
selecting one of the five places in the
priority list on the right side of the screen,
and selecting Patch To.
Reset to 1st
If the first source has failed, and the
system is running on any of the selections
2 to 6, when the first source becomes
available again, the system can be RESET
TO 1ST during any convenient off-air
period.
Save Options to Disk and Flash
The Options screens are used to preset
the system to the required settings. These
settings are not stored in the individual
console memories but are saved and
loaded separately. Changes to options
take effect as soon as they are made, but,
if they are not saved, the next time the
desk boots up the options will revert to
their previous settings.
