Product Description
RDL RU-RN22 Mic/Line Bi-Directional Network Interface 2x2
Overview
The RU-RN22 modules are Dante/AES67 audio network interface products compatible with microphones and line-level audio equipment inputs and outputs. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in commercial/industrial installations.
The RU-RN22 has two analog mic/line inputs, two Dante/AES67 network digital audio channel inputs, two Dante/AES67 network audio channel outputs and two analog mic/line outputs. Each output stage, local analog or network digital, is driven by an incorporated mixer fed from all four RU-RN22 inputs. Independent control of all mixer levels plus multiple DSP filters with adjustable parameters make the RU-RN22 far more versatile than a basic format converter. Each DSP filter may be set to None (audio pass-through), High-Pass, Low-Pass, Shelf High/Low or Notch Boost/Cut. Multiple filters may be set to the same function to obtain higher order filtering.
The RU-RN22 factory default settings provide high-quality converters that feed professional line-level outputs from two Dante/AES67 network received audio channels. Those settings also convert two analog line-level, dynamic or condenser microphone sources to Dante/AES67 network audio channels. The RU-RN22 provides an XLR or a detachable terminal block for connection to each analog input or output. Normal operating line level is +4 dBu balanced for -18 dBFS. The balanced terminal blocks may be wired unbalanced.
