Patent ID: 7366313

Claim:
A mixing console apparatus comprising: an input section that inputs a plurality of electric signals; a processing section that processes the inputted electric signals; an output section that outputs the processed electric signals; and a plurality of operators being provided in correspondence to a plurality of circuit components contained in those of the input section, the processing section and the output section, and being assigned with various functions in correspondence to the respective circuit components, the plurality of operators being manually operable to act on the corresponding circuit components for controlling the electric signals, said plurality of operators being divided into groups and subgroups, wherein the plurality of the operators are arranged to form a plurality of group operation sections such that the respective group operation sections have specific functions that are different from each other, wherein the plurality of the group operation sections are arranged in tandem with each other, wherein each group operation section is divided into subgroups with color markings such that operators belonging to one subgroup is distinguished from operators belonging to another subgroup by the respective color markings, wherein the subgroups belonging to one group operation section and the subgroup belonging to another group operation section correspond to each other, such that the corresponding subgroups include the same number of operators in the same arrangement, wherein all of the subgroups belonging to the plurality of the group operation sections are arranged in tandem, and the sequence of the subgroups in one group operation section is the same as the sequence of the subgroups in another group operation section, and wherein the color marking have a predetermined order, such that the color markings are applied sequentially to the sequence of the subgroups in the same manner among the respective group operation sections according to the predetermined order, so that the corresponding subgroups have the same color marking.
