RDL DDB-BN31 Wall-Mounted Bi-Directional Mic / Line Dante Audio Network Interface 4 x 4

The Radio Design Labs DDB-BN31 Pro Wall Plate puts Dante audio where you need it — at the wall. Engineered for AV integrators, security and surveillance teams, this wall-mounted 4 x 4 Dante network interface converts two XLR mic/line sources and a stereo mini-jack into Dante channels while providing four network-to-line outputs for monitoring and distribution. PoE-powered operation removes the need for separate power runs, and the unit fits a standard US dual-gang electrical box for tidy, professional installations.

Installers and system operators benefit from front-access switches that enable P48 phantom, select mic or line gain ranges (40/48/62 dB) and set mini-jack stereo/mono routing without special software. Rear output switches let you choose balanced professional or unbalanced consumer levels to match downstream equipment. Ideal for call rooms, control centers, video surveillance audio, paging and distributed monitoring, the DDB-BN31 delivers dependable, low-latency networked audio with flexible local I/O. Add this Radio Design Labs Pro Wall Plate to your next security or AV project for streamlined Dante integration and rapid commissioning.
