Bi-Directional Mic/Line Dante Interface 2 x 2 w/PoE - Black

BSW PART: DDB-BN22

DDB_BN22.JPG
The DDB-BN22 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. One switch enables or disables P48 phantom; the second switch selects the mic or line gain range; 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. The DDB-BN22 is PoE powered, and is available in multiple finishes with optional customized graphics.
