Jrc 4558 Ic Bass Treble Circuit Diagram. Also it uses an integrated circuit op amp that is low many noises or low noise. Figure 1 the circuit diagram of low noise pre tone control circuit using ne55532.
Ic 4558 is a monolithic integrated circuit designed for dual. So it makes a good sound and easy to build too. The megabass circuit is a modified baxandall tone control with no bass cut and no treble control.
And a transistor c945 as a buffer circuit and other components of resistors and capacitors.
It boosts frequencies from about 30hz to 160hz can boost by 14db. For more information just check passive low pass filter. We use the a ne5532 is the heart of the circuit. Parametric tone control ic4558 circuit diagram to increase the quality passive tone control this we must add the tone booster turbo bass subwoofer module or another pre amplifier circuit so that the sound that produced parametric tone control to be as original sound or even louder and powerful output.
