PURPOSE:To set a level of a graphic equalizer more quickly than a conventional level setting method by providing a frequency setting cursor switch moved in interlocking with a level of the preceding center frequency at level setting. CONSTITUTION:When the center frequency is at the position of 44 and its level is at the position of 46 (level '6') and when the center frequency is moved to an adjacent frequency 45 and set to the position of 47 (level '8'), the level is moved in parallel to the position 46 (level '6') without bringing the level to '0', and set to the position 48 (level '6') and then the level is increased by 1 to be set to the position 47 (level '8'). Cursor switches 49, 50 are switches for setting the center frequency, switches 51, 52 for setting the level are cursor switches in interlocking the center frequency setting level where the cursor switches 53, 54 are set to the preceding center frequency level in parallel movement. |
