Radio Design Labs' RU-NL4P modules are Dante audio network interface products compatible with line-level audio equipment inputs. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in commercial/industrial installations. The RU-NL4 is powered from an external 24 Vdc power supply, available separately. The RU-NL4P is equipped to operate from a PoE enabled network switch. The RU-NL4P will reserve power from the switch even while being powered from an external 24 Vdc supply. If PoE power and an external 24 Vdc supply are both feeding an RU-NL4P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply. The RU-NL4 is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured product is engineered and manufactured in the U.S.A for continuous duty in demanding installations.
