Renegade Labs Gray|328
Adjusting SDI Output SRC Controls
The Sample Rate Converter (SRC) control is used to bypass or enable
the SRC on the SDI output module.
BYPASS indicates that the SRC is not in the audio path. This is
the default setting. Bypass mode is used when the Gray|328 is
running at a 48kHz sample rate and locked to the same house
sync as the incoming SDI signal.
ENABLED indicates that the SRC is in the audio path. Any mis-
match or slip between the embedded audio sample rate and the
Gray|328 master clock is compensated for with the SRC. This
mode is used when the Gray|328 is running at the 96kHz or when
the input video and the Gray|328 are not locked to the same
house sync.
To adjust the SDI output module SRC:
1.
Enter into the Output Function Menu as previously described.
2.
Press the SELECT soft button to toggle to the SRC. The BYPASS or
ENABLE will be highlighted to indicate that it is selected.
3.
Press the CHANGE soft button to toggle between BYPASS and
ENABLE.
4.
Press the EXIT soft button to exit the Output Function Menu.
OR
Press the CANCEL soft button to abort the operation.
SDI Output Module Status
The SDI output module includes two status indicators to display
information regarding the incoming SDI signal:
•
INP:
There are 4 positions, each corresponding to the 4 groups in the
SDI signal, to the right of INP which indicate the following:
Symbol
Meaning
1, 2, 3, or 4
Indicates that an embedded group is present in that position and is
being passed through to the output.
-
No group is present in that position.
R
Embedder is replacing that group.
C
Embedder is cascading in a new group in that position.
X
The existing group in that position has been stripped out by the
embedder.

•
LOCK:
Indicates which SDI standard is present, SD or HD, and the
lock status of the two Phase Locked Loops (PLL) on the module: one
for video clock (V) and one for the audio clock (A). Normally, both A
and V should be displayed indicating that the module has locked both
PLLs. If one or both are missing, check your connection.
