RDL RU-NL4 4-Network to Line Level Interface, Provides +4 dBu with 18 dB Headroom

Bring Dante network audio into your line-level world with confidence. The Radio Design Labs RU-NL4 network-to-line interface converts four Dante channels into professional +4 dBu outputs with more than 18 dB of headroom, so AV integrators and security teams can route multichannel audio to mixers, amplifiers or recorders without clipping or added noise. Built around high-resolution 24-bit digital-to-analog conversion and RDL’s analog filtering, the RU-NL4 delivers low distortion and crosstalk below the noise floor—critical for intelligible paging, monitoring and surveillance audio.

Designed for commercial and industrial deployments, its compact metal chassis mounts in racks, on shelves or in furniture and includes signal and network LEDs for fast diagnostics on-site. Outputs mute automatically when digital streams are absent to protect downstream equipment; a PoE-capable hot-standby model (RU-NL4P) and 24V DC support give you flexible, redundant power options. Ideal for security, surveillance and large-scale AV networking projects, the RU-NL4 is a reliable bridge between Dante networks and line-level systems—contact your dealer to specify it for your next integration or security command center deployment.
