The RDL SF-BNC2 is a bidirectional Dante audio network interface. It features two unbalanced audio inputs (left and right) on RCA or stereo 3.5 mm Mini-jack connectors, as well as two unbalanced audio outputs (left and right) on RCA and stereo 3.5 mm Mini-jack connectors. Special software is not required to configure the SF-BNC2. Each input provides a network digital audio level of -20 dBFS for an unbalanced -10 dBV input. Each output provides -10 dBV unbalanced for a network digital audio level of -20 dBFS. The SF-BNC2 is a professional grade product for studio quality fidelity and low noise performance.

The SF-BNC2 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-BNC2 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.
