The Model 43D IFB Interface is a specialized audio interface designed for broadcast and related IFB (talent cue) applications. Four audio channels arrive by way of the Dante Audio-over-Ethernet networking technology. Two independent, 2-channel powered IFB outputs provide audio and 28 Vdc for supporting connection of portable listen-only user beltpack devices. (Compatible beltpacks include the popular Models 32A, 33, and 34 from Studio Technologies.) Two transformer-balanced line-level "–10" analog outputs are provided for connection to devices such as wireless IFB transmitters, battery-powered user beltpacks, and amplified loudspeakers. Excellent audio quality, ruggedized outputs, status LEDs, and audio level metering make this a sophisticated yet simple-to-use product. Housed in a lightweight "1/2-rack" enclosure with optional rack-mounting front panels. Can be powered by Power-over-Ethernet (PoE) or an external source of 12 Vdc. See Accessories for PS-DC-02 and PS-POE-01, purchased separately.
