Product Description

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 in multiple finishes with al 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.
