The RU-MLB2 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-MLB2 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.

Network to Line Level Interface Section

The RU-MLB2 converts two 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.

One front-panel green signal LED corresponds to each of the two Dante input channels. Received audio level is indicated on the variable-intensity LED indicator, facilitating setup when a networked computer is not connected at the module’s location.

Mic or Line Level to Network Interface Section

The RU-MLB2 converts two audio sources to Dante networked digital audio channels. Each input is equipped with a rear-panel input selector the installer sets to mic or line. In the mic position, the balanced input provides P48 phantom to an associated microphone jack. Connection of a dynamic microphone sets the preamplifier gain to 60 dB. Connection of a condenser microphone sets the gain to 40 dB. The automatic gain setting is always active so that no user adjustment is required when changing microphones. In the line position, the balanced input accepts a standard +4 dBu source, and the unbalanced line input terminals accept a -10 dBV source for normal operating level. Separate wiring terminals are provided for balanced and unbalances sources. A front-panel variable-intensity LED indicator is provided for each of the two inputs to facilitate setup.
