For the record, it's "IFB" as in "Interruptable FeedBack"...

Essentially this allows the field reporter/anchor to hear the other
"aircheck" audio(Studio anchor and taped segments)...

Usually is fed "MixMinus" which is a state that has everything except
the voice of the field reporter/anchor.  This is because the
satellite lag time for ones own voice is so distracting that it makes
it almost impossible to continue talking.

It also allows the field reporter/anchor to hear directions from the
producer back in the control room. (Hence, "Interruptable")
