6.7.2 Binaural audio over Optocore/ProGrid MADIs
Optocore/ProGrid MADIs allow each channel of the MADI to be routed
individually to any channel of any destination. The AES streams do not have to
be routed and configured in pairs. The ProGrid equipment allows fully flexible
routing and it is possible to mix close packed mono and conventional stereo
pairs on one MADI interface.
It is the routing matrix in the ProGrid equipment that is used to get the main
panel port to the A channel of the AES interface. Also, it is the routing matrix in
the ProGrid that is used to pair the audio channels as required.
In all cases, when using a router such as ProGrid, ensure that the
configuration of the E-MADI card and the configuration of the ProGrid
matrix are consistent with each other.
For example, if ports 1,2,3,4,5,7,9,11… are defined as panels in EHX, the
ProGrid must be used to ensure that the channels 1,2,3,4,5,7,9,11… are routed
to and from the A channels of the AES interfaces.
6.8 Set the EHX Audio Mixer screen option for
binaural audio routing
1) Select Configuration>Panels>Audio Mixer>Layout Basic Settings
in the EHX software and chose either Layout Binaural coax/AES or
Layout Binaural coax/AES + D25. See Fig. 6.6.
