KA2107 tone control circuit
A very simple tone control circuit project can be designed using the KA2107 integrated circuit manufactured by Samsung Electronics . As you can see in circuit diagram the KA2107 tone control circuit project is designed for stereo application and it has some additional functions like volume control and balance control between channels . Adjusting the 10k potentiometers (bass and tremble) you will modify the high and low output signal frequency .
This electronic circuit project must be powered from a simple 12 volt Dc power supply circuit , but it works fine also with a 8 volt or 14 volt DC power circuit .
