{"product_id":"rdl-ru-lb2","title":"RDL RU-LB2 – Bi-Directional Dante Line-Level Interface, 2x2","description":"\u003ch2\u003eWhat is the RDL RU-LB2?\u003c\/h2\u003e\u003cp\u003eThe RDL RU-LB2 is a bi-directional Dante network interface with two line-level inputs and two line-level outputs. It converts two consumer or professional line-level sources to Dante channels and converts two Dante channels back to balanced +4 dBu outputs. Front-panel gain trimmers and dual-LED VU meters make input setup possible without a networked computer at the module. It suits rack rooms, conference tables and equipment closets where analog gear needs to join a Dante audio network.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ru-lb2.jpg\" alt=\"RDL RU-LB2 Bi-Directional Dante Line-Level Interface, 2x2\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe line-to-network section accepts unbalanced -10 dBV or balanced +4 dBu sources on detachable terminal blocks. Each input has a front-panel gain trimmer and dual-LED VU meter, so the operating level preserves full headroom with the lowest noise floor. The network-to-line section converts two Dante channels to balanced outputs at +4 dBu for a network level of -18 dBFS. One green front-panel signal LED for each received Dante channel shows audio presence with variable intensity, which simplifies setup in the field. Conversion is 24-bit A\/D and D\/A, with more than 18 dB of headroom and a noise floor better than 80 dB below operating level. LED indicators show network sync status, and Ethernet Link and Speed indicators sit on the RJ45 connector. The RU-LB2 runs from an external 24 Vdc supply at 120 mA plus connected loads; RDL recommends the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX\u003c\/a\u003e, and the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-lb2p\"\u003eRDL RU-LB2P\u003c\/a\u003e adds PoE.
