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-ND2 is a digital audio interface that conver ts two Dante network audio channels to a stereo digital audio output. The
output is switch-selectable to provide an AES/EBU on XLR, or coaxial and optical S/PDIF. The switch enables the appropriate output jack and
any required electrical and data format conversion. Special software is not required to configure the module. The SF-ND2 is a professional
grade product for studio quality performance.
The SF-ND2 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-ND2 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.
