The RU-MLB4P 4x4 mic/line bi-directional Dante network interface with PoE provides professional, high-resolution audio conversion for commercial and industrial installations. This versatile unit converts four microphones or line-level sources to Dante network channels and simultaneously converts four Dante network channels to balanced line-level outputs, delivering seamless integration with professional audio systems. The front-panel LED indicators show both input and network channel audio levels, facilitating easy setup and monitoring.
Each input is switch-selectable for mic or line operation. Microphone inputs provide automatic gain of 40 dB for condenser mics and 60 dB for dynamic mics, along with P48 phantom power. Line inputs accept both balanced +4 dBu or unbalanced -10 dBV signals with over 18 dB of headroom. Output channels deliver +4 dBu balanced line level with low noise and minimal crosstalk, ensuring pristine audio quality across the system.
Powered via PoE or an optional external 24 Vdc supply, the RU-MLB4P supports normal and hot-standby operation, automatically switching between power sources without interrupting operation. Housed in a rugged all-metal enclosure, this unit supports surface, rack, or free-standing mounting, making it ideal for conference rooms, broadcast environments, and other professional networked audio applications. Built in the U.S.A., the RU-MLB4P is engineered for continuous-duty reliability and exceptional audio performance.
