RDL RU-LB4 RACK-UP Series Line-Level Bi-Directional Network Interface Converter

Streamline networked audio for commercial AV, security and surveillance systems with the Radio Design Labs RU-LB4 Dante audio network interface. This bi-directional RACK-UP series module converts four Dante receive channels to balanced line-level outputs (+4 dBu) and sends four line-level sources (supports -10 dBV and +4 dBu) onto the Dante network, enabling direct connection to mixers, amplifiers and DSPs without extra gear. Front-panel gain trimmers, per-channel signal LEDs and Dual-LED VU meters simplify setup and diagnostic work when a PC isn't at the rack. Choose PoE power with the RU-LB4P or use an external 24 VDC supply for flexible installs in racks, closets, conference rooms and monitoring hubs. With low noise floor, minimal crosstalk and a rugged all-metal chassis built for continuous duty, the RU-LB4 is engineered for demanding commercial, industrial and security deployments. Ideal for system integrators and IT teams who need reliable, low-latency audio transport for paging, intercoms, surveillance monitoring and distributed audio. Add the RU-LB4 to your networked audio rack to improve system reliability and simplify deployment—contact your distributor or order today.
