A global IFB means that any panel on the system will be interrupting the fold back audio going out on the IFB port.
Just follow this 4 step process to create one:
1. You need to enable the “Global IFB” in the “Advanced Settings” for the IFB port. Then, set the dim level or cutting level.
2. Add the IFB label to the panel or panels that need to talk to the IFB destination.
3. Route the audio to the IFB. To do this, go to “Local Advanced”, then “Forced Listen” and add a crosspoint from the PGM (source) port to the IFB destination port.
4. Perform “Apply Changes to Frame”.
