The SF-XMN4 is an interface that converts four XLR microphone inputs to Dante network audio channels. Special software is not required to configure the SF-XMN4. Each XLR input is equipped with a switch to set the gain for dynamic or condenser microphones. A dual-LED VU meter displays the level for each input to facilitate selection of the ideal gain range. P48 phantom voltage is supplied to each microphone input. The SF-XMN4 is a professional grade product with discrete mic preamplifiers for studio quality fidelity and low noise performance.

The SF-XMN4 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-XMN4 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.

SYSFLEX

The SysFlex® series is a family of A/V modules providing complex interface solutions at the click of a connector. Certain SysFlex modules provide connectorized interface between data networks and analog and digital audio devices. Other SysFlex modules include 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.
