Abstract
PURPOSE:To realize a correspondence to any type of specifications just through a change given to an operation part and a control signal generating circuit, by giving mixing to an optional channel signal into an optional combination with an optional level. CONSTITUTION:The digital signal of m channel supplied from an input terminal 6 is converted into a set level through an input interface circuit 7 and supplied to a multiplier 16 after time-division multiplication applied with every channel through a multiplex circuit 8. While the data obtained by an A/D converting means 10 is stored temporarily in a memory circuit 11. The operating information like a fader that is delivered from the circuit 11 and the zero signal supplied from a zero-level data generator 12 are switched through a selector circuit 13. This switching is carried out by the output of a switch signal generating circuit 14 consisting of a parallel input/series output shift register or the like that read the value set by a setting switch group 15. The result of the multiplier 16 is added and accumulated by an accumulator 17.
