The RDL RU-NL4 is a professional four-channel Dante network audio interface designed to deliver high-quality, line-level audio outputs for commercial and industrial installations. Ideal for equipment racks, conference tables, AV closets, and distributed audio systems, the RU-NL4 provides four balanced +4 dBu outputs from Dante network audio channels with exceptional clarity, low noise, and high headroom.
Each channel features a dedicated front-panel signal LED with variable-intensity indication, allowing quick visual confirmation of audio activity even when a computer is not connected to the network. Engineered for premium performance, the RU-NL4 delivers crosstalk levels below the noise floor and maintains a noise performance better than –80 dB, ensuring clean, reliable audio in demanding environments.
The RU-NL4 operates from an external 24 Vdc power supply, while the RU-NL4P variant adds PoE capability for hot-standby or redundant powering from PoE network switches. The unit intelligently switches to PoE if external power is lost, providing uninterrupted operation.
Built in a rugged, all-metal enclosure suitable for free-standing, surface-mounted, or rack-mounted use, the RU-NL4 is engineered in the U.S.A. for continuous duty and long-term reliability—making it an outstanding value for any Dante-enabled audio system.
