RDL DD-BN31


Bi-Directional Mic/Line Dante Interface 4 x 4 w/PoE - White

BSW PART: DD-BN31

DD_BN31.JPG
The DD-BN31 is a complete wall-mounted Dante audio network interface. It features two XLR mic or line inputs, one stereo Mini-jack line input and one stereo Mini-jack line output on the front panels, plus two line outputs on a rear-panel detachable terminal block. Special software is not required to configure the DD-BN31. 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 for that input; the second switch selects the mic or line gain range; the third switch sets the gain. The Mini-jack input provides a switch to configure the input for stereo or summed mono. The Mini-jack output provides a switch to configure the output for stereo or left-channel mono. Each rear-panel output provides a switch to set the output to balanced professional or unbalanced consumer level. The DD-BN31 fits a standard US dual-gang electrical box or an RDL WB-2 back box for installations in thinner European or equivalent walls. The DD-BN31 is PoE powered, and is available in multiple finishes with optional customized graphics.
