RU-RN44

RDL RU-RN44 - bidirectional Dante/AES67 network interface 4x4 microphone/line with 8x8 matrix and DSP

The RDL RU-RN44 is a wired, bidirectional Dante/AES67 audio interface from Radio Design Labs, designed to connect microphone and line devices to an audio network. The device offers 4 analog microphone/line inputs, 4 network inputs, 4 network outputs, and 4 analog microphone/line outputs. The built-in 8x8 mixing matrix allows any input - analog or network - to be routed to any output with independent level control, and programmable DSP filters provide capabilities far beyond a standard format converter. In factory settings, the module converts 4 analog sources to network channels and 4 network channels to analog outputs. Input gain is adjustable from 0-60dB, each input has phantom power P48 and a switchable compressor/limiter, and the analog outputs feature a microphone pad, 180° phase inversion, and protection against external phantom voltage. A delay of 2ms, THD+N distortion below 0.05%, and 24-bit conversion at 48kHz ensure high sound quality. Configuration, monitoring, and updates are done over the network using RDL Console 3 software, and volume and preset control are enabled by RDL D-NMC1R and D-NLC1R remote panels. The module is powered via PoE (class 0, IEEE 802.3af) or a 24V DC power supply. The steel housing from the RACK-UP series works with a full range of mounting accessories - from surface mounts to 19" rack enclosures to DIN rail adapters. The device is intended for rack cabinets, technical rooms, conference tables, shelves, and mounting panels in commercial and industrial installations. The product is covered by a 7-year manufacturer's warranty.

Functionality

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