D-RN22

Wall-Mounted Bi-Directional Mic/Line Dante Interface 2x2

The D-RN22 is a complete wall-mounted Dante or AES67 audio network interface. It features two XLR mic or line inputs on the front panel and two balanced line outputs on a rear-panel detachable wiring block. The module is configured and adjusted using RDL CONSOLE or other network control software. The D-RN22 fits a standard US single-gang electrical box or can be used with the RDL EP-1 adaptor for mounting in EU/UK square back boxes with 60 mm distance screw hole mounting centers. The D-RN22 is PoE powered and is available in multiple finishes with optional customized graphics.


Mic/Line to Network Section
The two XLR inputs are each converted to a separate Dante network transmit channel. Five gain settings are software-selectable for XLR inputs. Three gain settings are provided to match condenser or dynamic microphones. Two gain settings are provided to match standard line levels. P48 phantom voltage may be software enabled when an input is set for mic level.

Network to Line Section
Two Dante audio channels are converted to balanced line level feeding a rear-panel detachable wiring block. Each output provides +4dBu balanced for a network digital audio level of -18 dBFS. Each output is equipped with a software-controlled attenuator adjustable in 1 dB steps to a maximum attenuation of 63 dB then OFF. The outputs may drive local power amplifiers or may feed additional XLR jacks mounted adjacent to the D-RN22 in a dual-gang box. Two XLR mic or line outputs may be provided using an RDL D-D2 equipped with two AMS-XLRMA jacks, available separately.


Valid PoE power and synchronization to the Dante network are indicated by green LEDs visible from the front of the unit.

The D-RN22 is a professional grade product with RDL mic preamplifiers for studio quality fidelity and low noise performance, coupled through XLR jacks housed in a steel chassis with a powder-coated or stainless-steel Decora front plate.

The D-RN22’s superior performance specifications make it ideally suited to installations requiring network control and exceptional value in commercial networked audio systems. This full-featured product is engineered and manufactured in the U.S.A. for continuous duty in demanding installations. Designed to outperform. Built to last.
