Interruptible Foldback (IFB)
An audio source such as “on-the-air” or “program” audio can be routed
through the matrix to a presenters ear pieces. In a typical broadcast
application, program audio is routed to the “talent”– a collective term
for any person in front of the camera broadcasting directly to an
audience. A director or other audio person can then interrupt or dim the
program audio to the “talent” for announcements (commands) or cuing
by using the “interruptible foldback” or IFB feature.
