RU-RN04

RDL RU-RN04 - Dante/AES67 network interface for microphone/line 0x4 with 4x4 matrix and DSP

The RDL RU-RN04 is an audio interface Dante/AES67 from Radio Design Labs that converts network channels into analog microphone or line signals. The module has 4 Dante/AES67 network inputs and 4 analog microphone/line outputs. Each output is powered by an internal mixer that receives signals from all 4 network inputs, with independent level control. This allows the device to offer much more than a standard format converter. In factory settings, the RU-RN04 converts 4 network channels into professional line outputs. The balanced outputs are provided on XLR connectors and detachable terminal blocks, which can be wired unbalanced. Each output can programmatically enable a microphone pad that reduces the level from +4dBu to -46dBu, as well as a 180° phase reversal. The outputs are protected against external phantom voltage up to P48. Very low latency, THD+N distortion below 0.01%, and 24-bit A/D conversion ensure high sound quality. Configuration, monitoring, and updates are done over the network using RDL Console 3 software, and volume and presets can be controlled from RDL D-NMC1R and D-NLC1R panels. The module is powered via PoE (class 0, IEEE 802.3af) or from a 24V DC power supply. The steel housing from the RACK-UP series allows for mounting in rack cabinets, technical rooms, conference tables, shelves, and mounting panels. The product is covered by a 7-year manufacturer's warranty.

Functionality

• 4 Dante/AES67 network inputs and 4 analog microphone/line outputs
