Helixnet : Can I place the Helixnet PGM (input) into 2 separate IFBs
Yes this is possible, please note in HelixNet the Program Audio is cut for everyone listening to the IFB channel, not only at the IFB Destination.
Therefore if at your station you have access to a couple of IFBs and they are both using the same PGM input as the IFB source. Then the side effect is that if you are listening to both IFB1 and IFB2 channels and the program feeds both IFBs then cutting the program audio on one or the other has the same effect for you: no Program Audio is heard at your station
