DDB-BN2M - Overview

The DDB-BN2M 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 DDB-BN2M. Each XLR input provides three switches that may be set from the front of the unit when the cover plate is not installed. One switch enables or disables P48 phantom; the second switch selects the mic or line gain range; 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 DDB-BN2M fits a standard US dual-gang electrical box or an RDL WB-2 back box for installations in thinner European or equivalent walls. The DDB-BN2M is PoE powered, and is available in multiple finishes with optional customized graphics.

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 -18 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 DDB-BN2M. AMS audio connectors include RCA, Mini and XLR jacks. The output plate may be located together with the DDB-BN2M in a triple gang box or may be mounted remotely in a single box.

The DDB-BN2M is a professional grade product with discrete mic preamplifiers for studio quality fidelity and low noise performance,
