9. INTERCOM OPERATIONS
TALKING TO IFB (SOME MAPS CONTAIN IFB OPERATION)
IFB's or Interruptible Fold Backs are fixed audio routes which can be broken /
interrupted by a panel keying over the audio. When an IFB is keyed, the panel
replaces the original audio with his panel microphone. Therefore an IFB is made
up of three elements:
•
The IFB Destination - usually a 4-wire port.
•
The IFB Source. This is the "normal" feed to the IFB Destination.
•
The IFB Talker who keys over the source and interrupting the audio to the
destination.
IFB's can be used to interrupt background music on a PA system while someone
is paging. Normally in broadcasting presenters, talents, news anchors, guest, field
reporters, OB Vans etc are fed a mix of program sound. The Director or Sound
Engineer can then key over the program (interrupt) and talk to the talent or OB
Van.
The diagram below shows a typical example of an IFB. In this example the
Presenter on the Studio floor is normally listening to the program from the
Sound desk. When the Director presses the speak key to the Presenter, it breaks
the audio from the sound desk and replaces it with the audio command.
