Abstract
In a mixing system where a console, engine and I/O devices, each possessing a plurality of supply sources and destinations, are connected to a network, a plurality of transmission channels of the network are allocated to the individual devices. In response to human operator'"'"'s connection instruction given via the console for instructing a connection between a supply source possessed by one of the devices and a supply destination possessed by another of the devices, the device possessing the supply source transmits an audio signal of the supply source to the network using one of the transmission channels allocated to the device. The device possessing the signal supply destination, for which the connection instruction has been given, receives the audio signal transmitted via the transmission channel and supplies the received audio signal to the supply destination.
