Overview of GV Matrix Audio
GV Matrix supports audio by incorporating an audio router in the IFM-2T fabric module,
and by incorporating embedding and de-embedding of audio from SDI streams passing
through the XIO-4901 modular card. The XIO-4901 also provides access to the audio router
for MADI audio streams. There are no other discreet audio inputs or outputs to the GV
Matrix.
Audio functionality is affected by:
• The MDX option (see Options , on page 79) - enables embedding and de-embedding on
the XIO-4901.
• The GV Node Manager - the control point for selecting the status of audio on the XIO-
4901 inputs and outputs.
The audio functionality available at each of the XIO-4901 rear panel inputs (9) and outputs
(9) is summarized in the table:
