RDL RU-MLB2 Mic/Line Bi-Directional Network Interface

Bring reliable, professional audio I/O to your networked AV and security systems with the Radio Design Labs RU-MLB2 Mic/Line Bi-Directional Network Interface. Engineered as a compact Dante audio interface, the RU-MLB2 converts two Dante receive channels to balanced +4 dBu outputs while simultaneously sending two mic or line sources onto the network — ideal for conference rooms, surveillance audio, monitoring stations and distributed AV installations. Each input features automatic gain selection (60 dB for dynamics, 40 dB for condensers) and P48 phantom power when set to mic, removing the need for manual trim during device swaps. Front-panel variable-intensity LEDs speed commissioning when a laptop isn’t nearby. With low noise (better than 80 dB below operating level) and crosstalk below the noise floor, the unit preserves clarity for recording, security playback and live monitoring. Choose 24 VDC power or the PoE-capable RU-MLB2P for flexible mounting in racks, tables or backboards. Add the RU-MLB2 to your Dante network to streamline installations and improve audio quality for surveillance, monitoring and professional AV — order or specify it for your next project.

• Simplifies integration of analog mics and line sources into Dante AV networks for security, conferencing and monitoring systems
• Automatic mic gain and P48 phantom support eliminate on-site adjustments and speed deployments
• Balanced +4 dBu line outputs deliver clean, pro-level audio that interfaces directly with commercial amplifiers and recorders
• Dual-direction operation converts two Dante channels to line outputs and two mic/line inputs to Dante for flexible I/O routing
• Flexible power options (24 VDC or PoE available) allow installation in racks, closets, tables, or remote enclosures
• Compact, all-metal design with front-panel LEDs for quick setup and reliable performance in demanding installations
