The SysFlex series is a family of A/V modules providing complex interface solutions at the click of a connector. SysFlex modules provide connectorized
interface between data networks and analog and digital audio devices, networked and conventional amplifiers and other application-specific solutions.
In RDL’s tradition of versatility, SysFlex modules can be used right where they are needed: Rack-mounted, Surface-mounted, or unmounted. They
are light-weight, compact and easy to install with simple, straightforward switch settings and LED indicators. Modules quickly snap into the SysFlex
rack mount and each is firmly secured with a single screw. The racking system segregates network and power wiring from the audio and digital audio
connectors. For connectorized network audio endpoints and A/V system components that provide unparalleled performance and advanced features without
giving up simplicity and ease of installation, SysFlex is the industry’s best value.
APPLICATION: The SF-BNC2 is a bidirectional Dante audio network interface. It features two unbalanced audio inputs (left and right) on
RCA and 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.
