Mic/Line Bi-Directional Network Interface
The RU-MLB2P modules are Dante audio network interface products compatible with microphones and 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-MLB2P is a high quality converter that provides professional line-level outputs from two Dante network received audio channels. It also converts two professional or consumer line-level sources, or dynamic or condenser microphones to Dante network audio channels.
If PoE power and an external 24 Vdc supply are both feeding an RU-MLB2P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.

Note: For non-POE Version, please see 555-27660
