3.5.3 Audio Crosspoint
The audio crosspoint is located after the video crosspoint. The audio crosspoint routes
individual audio channels from external MADI inputs and from internal de-multiplexed audio
channels to external MADI outputs and to internal audio embedders on the video outputs.
The audio crosspoint is 736 x 928.
Sources of audio signals:
•
Vega 30 Router’s MADI audio inputs 1 to 3.
These inputs each contain up to 64 channels of audio.
•
Internal
‘
Audio De-muxes’:
These are de-embedded audio channels from each internal routed video signal. (16
channels of audio per routed video signal.)
•
Internal audio silence and test tones (not shown in figure).
Destinations for audio signals:
•
Vega 30 Router’s MADI audio outputs 1 to 6:
These outputs each contain 64 channels of audio.
•
Audio re-mux channels:
These are audio channels to be re-embedded into the routed video signals to form
the Vega 30 Video output. Each output has 16 embedded audio channels.
Figure 8 shows the routing architecture with audio channel source and destination numbers
annotated onto the audio crosspoint.
