Each mixer can act as a mixer, source selector, priority paging inserter or volume control. Four mixer outputs feed Dante channels and two drive balanced line-level outputs, so one module handles zone mixing, paging priority and level control in commercial systems.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/03\/ru-nmp44-1.jpg\" alt=\"RDL RU-NMP44 network mixing processor\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eFour Dante network inputs feed each of the six virtual mixers, with level adjustment in 1 dB steps on every input and on each mixer output. Two mixers can be paired for stereo audio. When ducking is used, one network input is assigned as the priority input and connected to all six mixers. An audio detector with installer-defined threshold and recovery delay can be assigned to any mixer, attenuating the other inputs to a fixed level between -10 and -64 dB during a page. Selectable high-pass filters help reject hum from a paging source. Up to four presets store routing, mixing and level settings and can be recalled by network command, an RDL remote, a switch closure or an open-collector output. The unit can power up to a preset, to its last settings or with all levels off. Configuration uses RDL CONSOLE or other network control software, and RDL network remotes such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-nmc1\"\u003eD-NMC1\u003c\/a\u003e provide user control.
