{"product_id":"rdl-ru-lb2p","title":"RDL RU-LB2P – 2x2 Line-Level Dante Interface, PoE","description":"\u003ch2\u003eWhat is the RDL RU-LB2P?\u003c\/h2\u003e\u003cp\u003eThe RDL RU-LB2P is a RACK-UP bidirectional Dante interface that converts two line-level sources to Dante and two Dante channels back to balanced line level. It connects mixers, DSPs, media players and amplifiers to a Dante network in one compact module. Inputs accept both -10 dBV unbalanced and +4 dBu balanced sources with more than 18 dB of headroom, and the unit runs from PoE.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ru-lb2p.jpg\" alt=\"RDL RU-LB2P line-level Dante interface\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eOn the network side, the RU-LB2P converts two Dante channels to balanced line outputs that deliver +4 dBu for a network level of -18 dBFS. Crosstalk stays below the noise floor across the audio spectrum and the noise floor is better than 80 dB below operating level. A front-panel green LED for each received channel indicates audio level, which helps setup without a networked computer on site. On the input side, two line-level sources are converted to Dante channels. Each input has a front-panel gain trimmer with a dual-LED VU meter, so installers can set an operating level that preserves full headroom with the lowest noise floor. Conversion is 24-bit with RDL analog filtering. LEDs show network sync status. The RU-LB2P runs from a PoE network switch, and with an external 24 Vdc supply also connected it switches to PoE automatically if that supply is lost. The module mounts in a rack or on a surface using RDL RACK-UP accessories such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-hra1\"\u003eRU-HRA1 10.4-inch rack mount\u003c\/a\u003e, \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-rc-1ur\"\u003eRC-1UR 19-inch universal rack chassis\u003c\/a\u003e, \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-sma1\"\u003eRU-SMA1 surface mounting plate\u003c\/a\u003e and \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-br1\"\u003eRU-BR1 under-surface bracket\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2x2 Dante interface\u003c\/strong\u003e — Converts two line sources to Dante and two Dante channels to balanced line outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible line inputs\u003c\/strong\u003e — Accepts -10 dBV unbalanced or +4 dBu balanced with more than 18 dB headroom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain trim and VU meters\u003c\/strong\u003e — Front-panel trimmer and dual-LED VU meter for each input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional outputs\u003c\/strong\u003e — +4 dBu balanced outputs with more than 18 dB headroom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal LEDs\u003c\/strong\u003e — Indicate audio on each received network channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoE with hot standby\u003c\/strong\u003e — Runs from PoE or 24 Vdc with automatic switchover.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRack or surface mount\u003c\/strong\u003e — Works with RDL RACK-UP mounting accessories.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is it typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConference rooms and boardrooms\u003c\/li\u003e\n\u003cli\u003eTraining rooms and classrooms\u003c\/li\u003e\n\u003cli\u003eAuditoriums and multi-purpose rooms\u003c\/li\u003e\n\u003cli\u003eHouses of worship\u003c\/li\u003e\n\u003cli\u003eGovernment and commercial facilities\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"\u003e\u003ctable border=\"1\" cellpadding=\"6\" style=\"border-collapse:collapse;width:100%;min-width:300px;table-layout:fixed;border-color:#ddd\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:44%\"\u003e\n\u003ccol style=\"width:56%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eNetwork Connector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRJ45 with Link and Speed indicators\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eDigital Audio Ethernet Protocol\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDante\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eTransmission Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eSample Rates Supported\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e44.1 kHz, 48 kHz (default)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eBit Depth Supported\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24 bits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eAudio Operating Levels\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-18 dBFS = +4 dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\" bgcolor=\"#f5f5f5\"\u003e\u003cstrong\u003eLine Inputs to Network Interface Section\u003c\/strong\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eInputs (2)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBalanced, detachable terminal block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput Level for +4 dBu\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-16 dBu to +12 dBu, +22 dBu maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput Impedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;
