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

BSW PART: DDB-BN2M

DDB_BN2Mpic1.JPG
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.
