True or False: IFB's can only be mono.

• A. True
• B. False
• C. Not sure
• D. Depends on model

Answer: (B)

An IFB (interruptible foldback) is a one-way audio feed from the control room to the talent for cues and talkback, and it isn’t tied to a single channel count. While many setups use a mono feed, you can configure IFB systems to deliver stereo as well, sending two separate channels to a stereo earpiece or to two drivers. This lets the talent receive different cues on each channel or monitor program audio on one side while hearing cues on the other. Hardware and workflow choices determine whether mono or stereo is used, so saying IFBs can only be mono isn’t correct.
