Prostage S.L.
Brainsystem developed the hard- and software for the StageWire® technology for the European company Prostage. StageWire is a bus system that enables several remote controllers and receivers to communicate with each other via single, standard microphone cables. StageWire is four times faster than the MIDI standard. Furthermore, the remote controllers are powered over the microphone cable. StageWire was developed especially for use on stage.
