RDL D-RN2ML

Overview

The D-RN2ML is a complete wall-mounted Dante or AES67 audio network interface. It features one XLR mic or line input on the front panel, one stereo Mini-jack line-level input summed to mono 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-RN2ML 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-RN2ML is PoE powered and is available in multiple finishes with optional customized graphics.

Mic/Line to Network Section
The XLR input is converted to a Dante network transmit channel. Five gain settings are software-selectable for the XLR input. 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 the XLR input is set for mic level.

Line Input(s) to Network Section
The Mini-jack input is converted to one Dante network transmit channel. The left and right Mini-jack inputs are actively summed. Three software-controlled gain settings are provided to increase or decrease the gain by 5 dB from the normal gain setting, optimized for an input level of -10 dBV.

Network to Line Outputs Section
Two Dante audio channels are converted to balanced line level, feeding a rear-panel detachable wiring block. Each output provides balanced +4 dBu 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-RN2ML 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-RN2ML is a professional grade product with an RDL mic preamplifier for studio quality fidelity and low noise performance, with audio coupled through XLR and Mini-jacks housed in a steel chassis with a powder-coated or stainless-steel Decora front plate.

The D-RN2ML’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.
