Audio Tone Control 3 Band
Audio tone control circuit can be used to set the tone of the bass tone 3, tone Midle and treble tones. Audio circuit 3 band tone control is built using TL072 IC for each channel. The system filters the tone used in auido 3 band tone control uses a system baxandal. OP Amp TL072 is used for building and reinforcing the front end amplifier with symmetrical supply voltage +15 Vdc and-15VDC. Complete circuit of audio tone control 3 band can be seen in the figure below.
