= Transcoder mode
Router Mode allows the user to route any input (MADI, AES or Analogue) to any output (MADI, AES
or Analogue). When multiple cards within a single frame are set to the same level they are treated as
a single larger router (refer to section 6.2.4 for details of internal expansion)
Transcoder Mode fixes the crosspoint and simply routes the AES or Analogue inputs onto the MADI
outputs and MADI inputs onto the AES or Analogue outputs with 1-1 mapping.
Example:
On an Analogue module set to 64 Channel MADI in transcoder mode…
MADI Input channels 0 and 1 route out to Analogue Output Port 1 L+R
Analogue Input Port 30 L+R route out to MADI Output Channels 58 & 59
(Full port mapping for Transcoder Mode is detailed in Table 26; it shows AES or Analogue Input to
MADI output – simply reverse for MADI input to AES or ANALOGUE output)
Vari-Speed is used when the module is in 56 or 64 Channel MADI Transcoder Mode and locks the
sample rate to the active MADI Input.
The module can dynamically switch between router and transcoder modes without a reset.
