The 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.

If ducking is used one of the four network audio inputs is assigned as the priority input. That input is connected to all six virtual mixers. An audio detector with installer-defined threshold and recovery delay may be assigned to one several or all of the six mixers. For each of those mixers the priority input is set to a defined level and the remaining three inputs are each set to attenuate to a fixed level between -10 and -64 dB when a message is detected on the priority input. If hum is anticipated from the paging source one of four high-pass filter may be enabled.

Up to four preset configurations may be stored in the RU-NMP44. Each preset can define any or all mixer level settings. A preset is activated by a network command an RDL network or wired remote control a momentary switch closure or a compatible open-collector from other equipment. The RU-NMP44 may be configured to power up to a preset to the last settings used or with all levels “off”.

The RU-NMP44 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 RU-NMP44 will reserve power from the switch even while being powered from an external 24 Vdc supply. If PoE power and an external 24 Vdc supply are both feeding an RU-NMP44 the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.

The RU-NMP44 is ideal for adding volume control mixing switching and ducking to existing network audio systems. 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.

The RU-NMP44 is constructed in a durable professional all-metal enclosure suitable for free-standing surface-mounted or rack-mounted operation. This full-featured product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. Built to last. Built to outperform.
