PROBLEM TO BE SOLVED: To minimize an error by determining a value of each boost/cut based upon a position of any height of a curve to cross two points near each reference line when setting acoustic characteristics of a graphic equalizer by drawing the curve on a touch panel. SOLUTION: A control part 7 graphically displays a slide groove for each of a plurality of bands on a display part 1, and senses the position of any height of an acoustic characteristic curve which is drawn on a surface of the display part 1 by contact from the outside to cross the slide groove by a sensor for at least two points near each slide groove. The control part 7 respectively calculates the inclination of the acoustic characteristic curve crossing each slide groove at positions for the two points and when the inclinations associated with the adjacent slide grooves are positively and negatively the same sign, the value of each corresponding band is set based upon the average position of the two points associated with the slide grooves and when the inclinations associated with the adjacent slide grooves are positively and negatively different signs, the intersection position of the inclinations is calculated. Then, the value of the band associated with the slide groove in which the average value of the two corresponding points is closer to the intersection position is set based upon the intersection position.
