The NEXUS Controller Card for Large Mixing Consoles
The RMC card is the heart of every AURUS or CRESCENDO mixer. It handles every single operation, manages the mixer projects and controls the entire data exchange between the console interface, the NEXUS network and the DSP cards assigned to the console. Up to two mixing console surfaces can be connected to one RMC card. In addition, there are connections for time code, MIDI and other controls such as RAS. The connection between RMC card and mixing console surfaces is established via LC-duplex optical fibres.
The actual, central mixing console module for the surfaces of the AURUS and CRESCENDO series is the RMC card. It is housed in the NEXUS Star Router and controls and links the operating actions with the audio processing. With a refresh rate of an incredible 100 Hz, it reads out all changes made to the mixer surface, calculates their effects and writes back updates for arc and level displays, graphs for EQs and dynamic units, selected layers and all other displayable values and of course the metering data so that they can be displayed by the console.
In addition to the large amount of control data, the audio channels required in the console are also transmitted via the connection. These are limited to the control room signal and the return channel for the talkback microphone. The RJ45 sockets located below the SFP ports allow an Ethernet connection to the console-internal PC, an additional socket allows the connection of an external control PC for a console-independent project configuration or protection in the event of an emergency.
DAW control software makes it possible to integrate and automate workstations that support the HUI or OASIS protocol with the console and mixing projects. The Virtual-Surface is a PC application that provides an additional mixer control panel. A time code signal for use especially with the dynamic automation of the AURUS mixing consoles can be fed in; a 15pin D-Sub socket is available to implement a RAS control via RS232 or RS422, via which fader starts or other mixing console functions can be triggered in an automated operation. In addition, there is a MIDI interface, e.g. to either receive or send MIDI messages and MIDI machine control contained in the automations.
