The stainless steel DDS-BN40 4 x 2 Wall-Mounted Bi-Directional Mic/Line Dante Interface from RDL is a complete wall-mounted Dante audio network interface. It features four XLR mic or line inputs on the front panels and two line outputs on a rear-panel detachable terminal block. Special software is not required to configure the DDS-BN40. 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 for that input, 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 DDS-BN40 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 four 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. 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 outputs are connected through a detachable terminal block.

The rear panel outputs are intended for connection to RDL AMS connectors mounted in Decora-style plates that match the DDS-BN40. AMS audio connectors include RCA, mini, and XLR jacks. The output plate may be located together with the DDS-BN40 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 DDS-BN40 features discrete mic preamplifiers for studio-quality fidelity and low-noise performance, coupled through metal XLR jacks housed in a stainless steel chassis with stainless steel Decora front plates.
