The SF-DN4 is a digital audio interface that converts two stereo digital audio sources to four Dante network audio channels. The SF-DN4 automatically detects a valid input on any of the three input jacks: S/PDIF optical, S/PDIF coaxial, or AES/EBU XLR. The input is decoded, re-clocked and transmitted to the Dante network. A yellow front-panel LOCK LED indicates a valid source received without any lock errors. Special software is not required to configure the module. The SF-DN4 is a professional grade product for studio quality performance. The SF-DN4 is PoE powered. Valid PoE power and synchronization to the Dante network is indicated by a green LED visible from the front of the unit. The SF-DN4 is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX® product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of SYSFLEX® products adds enormous flexibility in the design and installation of professional A/V systems.
