Product Overview
The Model 543D IFB Interface offers broadcast-standard powered and line-level analog IFB outputs through Dante® audio-over-Ethernet media networking technology. IFB, or "interruptible foldback," facilitates one-way audio signals for broadcast on-air talent and personnel during live-event broadcasts, crucially ensuring they remain informed. Widely utilized in sports and entertainment, IFB is indispensable for broadcast applications. Leveraging Dante's ease of use, high performance, and broad interoperability, the Model 543D extends these capabilities into the specialized realm of broadcast and production IFB, serving as a vital link in the communication chain for seamless coordination during live broadcasts.
