MADI Presence
MADI Presence on each of the four input streams is automatically detected and reported in the
MADI
Present
section of the
MADI Input
category.
If MADI is present, the following information is reported:
The number of channels per input stream (32, 56, or 64) along with the sample rate for each stream.
Each MADI input is divided into chunks of 16 channels (1-16, 17-32, 33-48, and 49-64) and these are
reported as active or not.
TDM Mapping
Through the PT-MADI4X-IBG parameter interface, channels in MADI inputs can be manually mapped to
the TDM stream and you can select if one or all of the MADI inputs contribute to the stream. A
maximum of 128 mono channels can be mapped to the TDM stream.
The
Mapping
parameter category provides a
MADI to TDM map
section in which you can select the
channels in each stream to map to the TDM.
For each of the 4 inputs, you can choose whether or not its channels contribute to the TDM stream.
Unused channels in the TDM stream are muted. Mapping from MADI inputs to the TDM stream has a
granularity of 32 channels, aligned at 32-channel boundaries. 56 channel formats are treated as 64
channel formats, with the unused uppermost channels always muted.
