RDL RU-NL4P Network to Line Level Interface

The Radio Design Labs RU-NL4P Network to Line Level Interface is a purpose-built Pro Audio Processor that brings Dante network audio into professional line-level systems with reliability and sonic transparency. Ideal for AV integrators, security and surveillance installers, and corporate conferencing, the RU-NL4P converts four Dante channels to +4 dBu balanced outputs with 18 dB of headroom and high-resolution 24-bit digital-to-analog conversion. Legendary RDL analog filtering and exceptionally low noise/crosstalk keep audio clear for paging, monitoring and recording workflows. PoE-enabled normal or hot-standby operation minimizes power cabling while LED indicators provide immediate network sync and per-channel signal status—making rack, closet or table installations faster and easier. Outputs automatically mute when digital inputs are inactive to protect downstream equipment and maintain clean system behavior. Deploy the RU-NL4P to streamline network audio distribution in AV, security, surveillance and monitoring environments, or contact your integrator to specify it in your next system design.

• Seamless Dante-to-line conversion: delivers four network audio channels as professional +4 dBu outputs for simple integration into AV, security and monitoring systems
• Studio-grade sound with 24-bit DAC and 18 dB headroom: ensures low-noise, low-distortion audio and crosstalk below the noise floor for critical listening applications
• PoE with normal or hot-standby operation: reduces wiring complexity and improves uptime in distributed installations
• Compact rack/desk mounting with status LEDs: fits closets, racks, conference tables or shelves and provides clear network sync and signal indication for faster troubleshooting
• Outputs mute automatically when inputs are inactive: protects downstream equipment and maintains clean system operation in surveillance and conferencing setups
