<P>PROBLEM TO BE SOLVED: To speedily, surely, and simply recognize a present set point of the whole range to which a parameter can be set. <P>SOLUTION: A parameter display part of an acoustic signal processor (mixer) according to this invention displays a value of one parameter (a parameter for setting a channel group) by using a plurality of light emitting type display elements (LED) La to Lc, and the display elements La to Lc in the whole range to which the parameter can be set are in display operation. In that case, the display elements [(2)=La, (3)=Lb, (4)=Lc] corresponding to a set content are controlled so as to display in a 1st display mode (bright lighting), while the other display elements [(2)=Lb, Lc, (3)=La, Lc, (4)=La, Lb] not corresponding to the set content are controlled so as to display in a 2nd display mode (dimmed lighting). <P>COPYRIGHT: (C)2004,JPO&NCIPI |
