Reference lock only mode
•
A group of pairs or a MADI stream can be locked to the AES reference or one of the
four physical video reference inputs without sample rate conversion being enabled.
•
If no reference signal is present on the selected reference input all the SRCs on
the 4929 module using that reference input will be free running and independent
of any other module in the frame.
Example reference lock only mode (AES)
SRC settings required for reference lock only mode on a group of eight AES pairs locked to
video reference 1 (See Figure 115 on page 178 for setting locations):
SRC rate
: Any
SRC Reference
: Ref 1
SRC Enable
: Unchecked
Use SRC
: Unchecked
Example reference lock only mode (MADI)
SRC settings required for reference lock only mode on a MADI stream locked to the AES
reference (See Figure 116 on page 178 for setting locations):
SRC Rate
: Any
SRC Reference
: Ref 5
SRC Enable
: Unchecked
Use SRC
: Unchecked
Note:
•
AES
- If channels within a pair are asynchronous to each other then sample drop or
repeat is used on the right channel to match the left channel.
•
MADI
- If channels from the audio crosspoint are asynchronous to each other then
sample drop or repeat is used on all channels to match the first active channel in
the MADI stream.
