Recently I picked up a RCI 2970N2 and added talkback to it that runs on/off via a switch and I am now in the last 2 weeks experimenting with studio audio via a Yamaha mixer board and a Behringer dynamic microphone! Only great reports on the audio quality!
Your FX1 makes the hook ups to the radio and mixer board so easy and has worked flawlessly so far.
Thanks Rich! 73s!
