Overview
Studio Technologies Model 543D IFB Interface, with Dante Audio-over-Ethernet technology
The Model 543D IFB Interface provides broadcast-standard powered and line-level (non-powered) analog IFB outputs from audio signals that are supplied by way of Dante® audio-over-Ethernet media networking technology. IFB, also known as "interruptible foldback" or talent cueing, is a method commonly used by broadcast on-air talent and related personnel to receive one-way (listen-only) audio signals associated with live-event broadcasts. Especially important in sports and entertainment events, IFB plays a crucial role in virtually all broadcast applications that require people to stay "in the know." Dante has found wide acceptance as an audio "backbone" due to its ease of use, high performance, strong interoperability, and wide adoption by a large number of equipment manufacturers. The Model 543D is a unique product that helps to extend Dante’s capabilities into the important but specialized world of broadcast and production IFB.
