{"product_id":"rdl-ddb-bn31","title":"RDL DDB-BN31 – Black 4x4 Dante Mic\/Line Wall Plate Interface","description":"\u003ch2\u003eWhat is the RDL DDB-BN31?\u003c\/h2\u003e\u003cp\u003eThe RDL DDB-BN31 is a wall-mounted 4 x 4 Dante mic\/line interface in a black Decora-style finish. It provides two front-panel XLR mic\/line inputs and a stereo mini-jack line input, along with a front-panel stereo mini-jack output and two balanced line outputs on a rear-panel terminal block. It converts four analog sources to Dante network channels and returns four Dante channels to analog, all powered from a single PoE network connection. Every setting is made with on-board switches, so integrators can commission a Dante wall plate in a conference room, training room or multi-purpose space without special configuration software.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ddb-bn31.jpg\" alt=\"RDL DDB-BN31 black 4 x 4 Dante mic\/line wall plate interface\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe DDB-BN31 installs in a standard North American dual-gang electrical box (4\" square deep recommended) or an RDL WB-2U international wall box for thinner European-style walls. Each XLR input has three switches, reachable from the front with the cover plate removed: one enables P48 phantom power, one selects the mic or line range and one sets the gain. Mic gain is switch-selectable at 40 dB, 48 dB or 62 dB to suit dynamic or condenser microphones, and each XLR input feeds its own Dante transmit channel. The front-panel stereo mini-jack input feeds two Dante transmit channels at -20 dBFS for a -10 dBV source, and a selector sums left and right to mono for single-channel playback devices. The front-panel mini-jack output normally carries Dante receive channels 3 and 4 in stereo, or channel 3 to both sides in mono mode. The rear-panel terminal-block outputs deliver +4 dBu balanced for a -20 dBFS network level, and a per-output switch on top of the chassis converts each one to -10 dBV unbalanced for consumer equipment. Those outputs are intended for RDL AMS connector modules (RCA, mini-jack or XLR) in matching Decora plates, which can share a triple-gang box with the interface or mount remotely in a single-gang box. Green front-panel LEDs confirm valid PoE power and Dante network sync, which speeds up troubleshooting during commissioning. Discrete mic preamplifiers, 24-bit A\/D and D\/A conversion and metal XLR jacks in a stainless steel chassis give studio-grade fidelity in a commercial wall plate built in the U.S.A.
