<p>PROBLEM TO BE SOLVED: To reproduce a sound signal which is dynamic and is rich in presence with a simple operation and to improve operation convenience by performing display in which switching to a low-pitched sound reinforcement processing means or/and the adjustment of a sound output converting means are possible. SOLUTION: Application software where an interacting means of a graphic user interface(GUI) is available is stored in a storage medium 10 of a RAM 10, etc. When a user selects the GUI, a controlling part 12 displays a graphic pattern representing a low-pitched sound reinforcement function on the screen of a displaying means. A pointer shown on the screen is moved to a slide knob position by a mouse and moved to a prescribed position, and when a click is performed, volume setting and volume disconnection setting at initialization are performed. When an on button for low-pitched sound reinforcement is clicked at the pointer, the part 12 switches to a lowpass boost circuit 4 side through a bus 9. Thus, an operator can select a lowpass reinforcement effect by actually recognizing the lowpass reinforcement effect.</p> |
