Ideal for adding volume control, mixing, switching, and ducking to existing network audio systems, the RDL RU-NMP44 is a network mixing processor containing six virtual audio mixers controlled by network commands from RDL and other network remote controls. Each mixer operates independently with input signal attenuation from unity to off. The output level from each mixer is independently adjustable from unity to off. Based on the commands sent to the RU-NMP44, each mixer can be used as a mixer, a source selector, a priority paging inserter and/or as a volume control. The outputs from four of the mixers drive corresponding network audio channels. The outputs from two of the mixers drive line-level +4 dBu audio outputs.
The RU-NMP44 is configured using RDL CONSOLE or other network control software. The unit may be powered from an external 24 VDC power supply, available separately. The RU-NMP44 is equipped to operate from a PoE enabled network switch. The digital signal processing offered in the RU-NMP44 often fulfills all the requirements for an audio system design, such as in classrooms, meeting rooms, restaurants/bars, fitness gyms, and retail stores. The RU-NMP44’s superior performance specifications make it ideally suited to the most demanding installations, and an exceptional value in commercial networked audio systems.
