TDM Output Mapping

Reference locking is controlled by the following parameters:
TDM Reference Source in the

(options are Sync1, Sync2, or Sync3)
MADI Reference source in the

(options are Sync1, Sync2, Sync3, or Same as TDM Ref.)
By default, audio encapsulated into the MADI transport stream is locked to the same
reference as the TDM receiver.
Using the TDM reference for MADI (default option)
If you select the same reference for MADI as for TDM ("Same as TDM Ref" option),
non-PCM data such as Dolby-E or Dolby-D can also be encapsulated into the MADI
transport stream.
Using a separate (non-TDM) reference for MADI
If the reference signal for MADI is different than the one used for TDM locking, channels
conveying non-PCM data (such as Dolby-E/D) are destroyed. Non-PCM data becomes
unusable because of a sample-rate conversion process that transfers received TDM data into
a new clock domain (MADI). As a workaround - for example, when you need to lock the
TDM data to a video reference - lock the MADI audio data to an unrelated 48kHz DARS
reference.
The TDM Input section reports on audio presence and format for each of the 128 mono
audio channels that can be received by the TDM receiver. Possible Audio formats are PCM,
non-PCM, Dolby-E, and Dolby-D.
You can map portions of the TDM stream to one or more of the four MADI outputs. The
MADI Output Format section provides mapping options for each of the 4 MADI Outputs.
You can map predefined channel ranges in chunks of 56 or 64 channels. The following
options are available:
TDM 1-56 (56 channels)

TDM 33-88 (56 channels)

TDM 65-120 (56 channels)

TDM 1-64 (64 channels)

TDM 33-96 (64 channels)

TDM 65-128 (64 channels)
