Product Description

The RU-MLB4 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. Application: The RU-MLB4 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, or dynamic or condenser microphones to Dante network audio channels. Network to Line Level Interface SectionThe RU-MLB4 converts four Dante audio channels to balanced line level. Each output provides +4 dBu balanced for a network digital audio level of -18 dBFS. The professional output directly interfaces with other professional and commercial equipment without the need for additional gain. Crosstalk is below the noise floor between all outputs across the entire audio spectrum. The noise floor is better than 80 dB below operating level.
