Sample rate
➭
General Sample Rate
– Set the general sample rate for the SDI unit to match
the wider environment.
➭
Sample Rate Adaptation Source
allows the unit’s sample rate to be
automatically adjusted as an external device changes.
The adaption source can be set to any of the separate or embedded clock
reference signals.
➭
Word Clock Output Sample Rate
– Used to set the word clock to 48kHz or
44.1kHz (for use if the general sample rate is a higher rate e.g. 96kHz –
sometimes called legacy mode).
Synchronization
Set the hierarchy of clock sources. Double-click in the
Priority
cell to alter the
settings.
word/video Sync Termination
Select the sync termination box to add 75Ω terminator to the sync input BNC.
MADI

Optional Module
tab.
➭
Input Sample Rate
can be determined automatically from the incoming
signal or locked to the internal clock.
➭
Output Frame Rate
sets the frame rate of the MADI signal (for use at 96kHz):
• High – 96kHz framing pattern
• Legacy – 48kHz framing pattern
➭
Output Channel Status
controls user-bit data handling:
• Transparent – Provides pass-through of user bits
• Default – Removes user bits
➭
Output Channel Count
– Select 56- or 64-channels
