The black DDB-BN22 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 and two XLR mic or line outputs on the front panels. Special software is not required to configure the DDB-BN22. 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 XLR output provides a switch to set the output to balanced professional line level or mic level.
The DDB-BN22 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 front panel XLR jacks. Each output provides +4 dBu balanced for a network digital audio level of -20 dBFS. Each output is equipped with a selector to set the output to line level or attenuate the output by 50 dB to mic level. These switches are located on the top of the chassis and are set by the installer prior to mounting the unit.
The valid PoE power and synchronization to the Dante network are indicated by green LEDs visible from the front of the unit. The DDB-BN22 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.
