In broadcasting routing for IFB, which path is used according to the material?

• A. Pre aux sends
• B. Post aux sends
• C. Both
• D. Neither

Answer: (B)

The key idea is that the IFB feed should track what’s on the air. To make that happen, the IFB signal is sent from each channel through a post-fader auxiliary send. That means the path to the talent’s earpiece is after the channel fader, so when the show’s levels change (fader moves or master adjustments), the IFB level changes in step with the program.

If the feed were pre-fader, adjustments to a channel’s fader wouldn’t affect the IFB level, which can lead to the talent hearing something out of balance with the on-air mix. Using the post-fader aux path also lets you control the overall IFB level via the aux master, independently of the original source levels, while still preserving the needed synchronization with the program.

So the material specifies using the post-fader aux sends for the IFB routing.
