Description

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.

The RU-MLB2P is equipped to operate from a PoE enabled network switch. The RU-MLB2P 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-MLB2P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.

Features:

  • Interfaces Two Dante Inputs and Two Dante Outputs
  • Converts Two Standard Mic or Line Audio Sources to Dante Network Channels
  • Each Input is Switch-Selectable for Mic or Line
  • No User or Installer Gain Adjustments are Required
  • Automatic Microphone Gain of 40 dB for Condenser Mics and 60 dB for Dynamic Mics
  • P48 Phantom is Provided on Each Microphone Input
  • Line-Level Inputs Accept Unbalanced -10 dBV or Balanced +4 dBu Signals with > 18 dB Headroom
  • Front-Panel Signal LED for Each Audio Input
  • Converts Two Dante Network Audio Signals to Balanced Line Level
  • Line-Level Outputs Provide +4 dBu with > 18 dB Headroom
  • Signal LEDs Indicate Audio for Each of the Received Network Signal Channels
  • High Resolution 24 Bit Analog to Digital and Digital to Analog Conversion
  • Legendary RDL Analog Filtering Enhances Superb Audio Performance
  • LED Indicators Show Network Sync Status
  • Normal or Hot-Standby Operation from PoE (Model RU-MLB2P)
  • Equipped for Rack Mounting or Surface Mounting

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.

The RU-MLB2 is powered from an external 24 Vdc power supply, available separately. The RU-MLB2P is equipped to operate from a PoE enabled network switch. The RU-MLB2P 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-MLB2P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.

The RU-MLB2's superior performance specifications make it ideally suited to the most demanding installations, and an exceptional value in commercial networked audio systems.

The RU-MLB2 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. Built to last. Built to outperform.
