This is a five band graphic equalizer circuit. Comparatively this is a very simple diagram and working voltage is 8 volts. However you can supply up to 15 volts, but we do not recommend that much of supply. The specialty of this circuit is it operates by eighteen pins of a single chip IC ( BA 3812L ). The other components are very less.
The five frequency bands are 100Hz , 300Hz, 1kHz, 3kHz, 10kHz . You can use this simple equalizer with Hi Fi amplification systems as it provide low noise, wide dynamic range and very low distortion. If you want you can use two ICs of BA 3812L and make 10 band graphic equalizer.
