PURPOSE:To simplify the operation, to improve the space efficiency and to reduce the cost by providing a means discriminating number of times of depression of a key switch and applying start or stop of cyclic readout depending whether number of times of depression is an odd number or an even number. CONSTITUTION:With a key switch 2 depressed once, a graphic equalizer decoder cyclic readout means 22 including a preset memory storing a data of a graphic equalizer curve starts its operation. Then a sequential data is read and outputted from the preset memory for each prescribed time. The data output is started again from the beginning when the data readout stored in advance is circulated. When a desired equalizer curve is displayed on a display device and the key switch 2 is depressed again, the operation of the graphic equalizer data cyclic readout means 22 is stopped and the data at that time is consecutively outputted. Then the desired equalizer curve is set by having only to operate a single key switch twice. |
