RDL DDBBN2M Overview

The white DD-BN2M 2 x 2 Wall-Mounted Bi-Directional Mic/Line Dante Interface from RDL is a complete wall-mounted Dante audio network interface. It features two XLR mic or line inputs on the front panels, plus two line outputs on a rear-panel detachable terminal block. Special software is not required to configure the DD-BN2M. Each XLR input provides three switches that may be set from the front of the unit when the cover plate is not installed. The first switch enables or disables P48 phantom, second switch selects the mic or line gain range, and the third switch sets the gain. Each rear panel output provides a switch to set the output to balanced professional or unbalanced consumer level.

The DD-BN2M fits a standard US dual-gang electrical box or an RDL WB-2 back box for installations in thinner European or equivalent walls. It is PoE powered and is available with optional customized graphics.

The two XLR inputs are each converted to a separate Dante network transmit channel. Three gain settings are switch-selectable for both the mic and line input ranges to match condenser or dynamic mic levels and standard line levels.

The two Dante audio channels are converted to balanced line level on the rear panel detachable terminal block. Each output provides +4 dBu balanced for a network digital audio level of -20 dBFS. Each output is equipped with a selector to unbalance the audio and attenuate the level to -10 dBV. These switches are located on the top of the chassis and are set by the installer prior to mounting the unit.

The rear panel outputs are intended for connection to RDL AMS connectors mounted in Decora-style plates that match the DD-BN2M. AMS audio connectors include RCA, mini, and XLR jacks. The output plate may be located together with the DD-BN2M in a triple gang box or may be mounted remotely in a single box.

The valid PoE power and synchronization to the Dante network are indicated by green LEDs visible from the front of the unit. The DD-BN2M features discrete mic preamplifiers for studio-quality fidelity and low-noise performance, coupled through metal XLR jacks housed in a stainless steel chassis with dual powder-coated Decora front plates.
