Abstract:
1. A digital mixing system having a plurality of input signal systems and a plurality of output signal systems, wherein input signals from said plurality of input signal systems are subjected to a mixing process and the mixed signals are output to said plurality of output signal systems, the system comprising: a console section including panel operating elements used to input parameters relating to the mixing process, a computer connection interface, a first communication interface, an output device that outputs at least a mixing control signal in response to operation of said panel operating elements, and a first non-volatile memory that stores a first operation program; an engine section including a mixing processing device that executes the mixing process of mixing the input signals from said plurality of input signal systems based on the mixing control signal output from said output device and outputting the mixed signals to said plurality of output signal system, a second communication interface, and a second non-volatile memory that stores a second operation program; communication lines connecting between said first communication interface and said second communication interface; and a computer connected to said computer connection interface; wherein when said computer connected to said computer connection interface executes an upgrading program, the first operation program stored in said first non-volatile memory and the second operation program stored in said second non-volatile memory are upgraded.
