First time poster here...
I thought the TRXFB3 might be useful for a Director or Producer making verbal notes (as long as they remember to press the button!) and getting an IFB feed to them as well...another channel to record but could be useful for Post?
The only issue I have is, as with all my Zaxnet 2.4GHz equipment, I am running into interference from wireless Camera & Video when distance between the transmitter and the IFB receiver becomes too far. So for my critical/main client audio feed I have the RX200 go to Video Village - which solves most of my issues.
