How many separate IFBs can the Model 41 Interface create?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (C)

An IFB is a private audio feed for someone involved in the production to hear the program without it going out on the main mix. The Model 41 Interface is designed with multiple independent outputs, each capable of carrying its own feed. Because there are four separate outputs, you can route four distinct IFB channels to different recipients, keeping each feed isolated from the others. That means you can create four separate IFBs with this device. Trying to go beyond four would require another interface or a shared feed, which would lose the separate, private nature of each IFB. So, the number of separate IFBs you can create is four.
