Mixing console having visual marking system applied to manual operators with subgrouping

摘要

In a mixing console apparatus, an input section inputs a plurality of electric signals, a processing section processes the inputted electric signals, and an output section outputs the processed electric signals. A plurality of operators are provided in correspondence to a plurality of circuit components contained in those of the input section, the processing section and the output section, and are assigned with various functions in correspondence to the respective circuit components. The operators are manually operable to act on the corresponding circuit components for controlling the electric signals. The plurality of the operators are arranged to form at least one group operation section such that the operators having similar functions are grouped into the same group operation section. The group operation section is divided into subgroups with markings such that operators belonging to one subgroup is distinguished from operators belonging to another subgroup by the respective markings.
