RU-LB4P

The RU-LB4 modules are Dante audio network interface products compatible with line-level audio equipment inputs and outputs. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in commercial/industrial installations. The RU-LB4 is a high quality converter that provides professional line-level outputs from four Dante network received audio channels. It also converts four professional or consumer line-level sources to Dante network audio channels. If PoE power and an external 24 Vdc supply are both feeding an RU-LB4P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.
