SF-BNC2

Bidirectional Unbalanced Stereo Audio Network Interface

The 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.
