PURPOSE: To immediately know what frequency characteristics are given to an audio signal at present, by displaying control data in two dimensions on a display device which performs the two-dimensional display.
CONSTITUTION: A display part 26 consists of a matrix display device 26a and pilot lamps 26f∼26l provided in respective keys 25f∼25l, and the matrix display device 26a performs two-dimensional display by arraying 5×9 dot display elements 26al in a matrix. When the pilot lamp 26f of the memory key 25f is turned off, the contents of a corresponding preset memory are supplied as they are to an output data memory and at this time, analog switches are controlled by previously stored control data, namely, preset data to obtain corresponding equalizing characteristics, which are displayed on the display device 26a.
