RU-NMP44

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.

Allen & Heath – dLive DM48

The MixRack is the heart of any dLive system. It houses the XCVI processing core complete with audio I/O, control and audio networking ports. It is typically connected to a dLive Surface, but can also be controlled at the same time as or even without a Surface using a laptop or iPad, Allen & Heath IP remotes or third party controllers via TCP/IP. There are 3 sizes of dLive MixRack available. All feature the same mix engine and differ only in the number of analogue I/O. All models can work with the full 128 channels by adding DX expanders or patching digital sources.

Nixer – RL128

A 1U 19inch rack mounted AoIP monitoring and mixing unit.

4 models are available the RL64, RL128, RL192 and RL256 and each unit can be configured at time of purchase to be Dante or Ravenna

RL Series units allows two modes of operation a mixing mode which can mix up to 256 channels at 48kHz (128 channels at 96kHz) plus microphone input (via headphone connector) and AES input to create a 259 into 2 mixer. Alternatively, it can be set into a simple Listen mode where touching a channel instantly routes to the LR output and cancels any previous selection.

The outputs of the LR bus are presented to the user via the inbuilt 4mm x 9mm full range speakers or via the 3.5mm headphone jack. The speakers are automatically muted when a headphone jack is inserted. Simultaneous outputs are also available in the form of the stereo balanced line outputs and AES output accessed via XLR connectors on the rear of the RL Series Unit. The mix output is also routed to the AoIP output.

The RL Series units are operated and controlled via the large letterbox 6.6” diagonal (168mm) 1440 x 240 24-bit colour LCD and capacitive touch panel.

A simple and elegant menu system has been designed to be intuitive to navigate allowing the user to access all the features of the RL Series unit very quickly.

The high-resolution screen is easy to read presenting comprehensive metering, routing and status information to the user.

Firmware updates of the RL Series unit are achieved via a dedicated USB micro AB connector on the front panel. There is also a dedicated 3.5mm jack socket for the headphone output

On the rear of the RL Series unit there are 4x Primary and Secondary ports for up to 4x AoIP inputs. 2x balanced line outputs on 3 pin male XLRs and AES output also on 3 pin male XLR. These outputs can be configured to follow the main volume settings of the speakers/headphones or they can also be set to follow the main Mute control.

Additionally, there is an AES input via 3 pin female XLR connector

The RL Series unit can be powered via either of the two 2.5mm DC input connectors requiring 24V @ 2A. These inputs also have a screw lock to prevent accidental unplugging. Using both inputs provides redundancy.
