Abstract

PURPOSE:To accomplish a desired tone quality characteristics with a simple operation, by controlling a boost circuit of low, medium and high tone with an output signal of a programmed logical circuit in advance with the selection of a tone quality selection button. CONSTITUTION:A signal applied to a signal input terminal 1 is inputted to an operational amplifying circuit 3 and given at an output terminal 3, and also inputted to a low frequency boost circuit consisting of a resistor 6 and a capacitor 7, medium frequency boost circuit consisting of resistors 10, 13 and capacitors 11, 14, and high frequency boost circuit consisting of a resistor 16 and a capacitor 17. Further, with a control signal obtained at an output terminal of a logical circuit 19 programmed in advance according to the selection of tone quality selection buttons 20a, 20b...20l, a connecting switch 9, selector switch 8, and connecting switches 15 and 18 are controlled to set the frequency characteristics to the desired presence, sound volume and balance.
