This is the diagram od electro-harmonix graphic equalizer. You can specify the number of channels according to your needs. You just need to parallel the components: C1, C2, R1, an om-amp, Potensiometer and a 470 ohm resistor. The frequency to be boost decided by C1, C2 and R1. See the diagram for the C1, C2 and R1 combination versus the frequency.

For the op-amp, you can use op-amp IC TRX6221, NE5532 or LM833. Use regulated power supply and high quality components to obtain the quality audio output.

Here the 20 band graphic equalizer schematic diagram. This is stereo graphic equalizer, it should be 2×10 channel equalizer. Graphic equalizers device are popular with both domestic users and professional users. This equalizer is has simple design and easy to construct. It has no coil. It uses 15V split / dual polarity power supply to work (+15V / 0? / -15V). You may use search menu to find the circuit diagram of split / dual polarity / symmetrical power supply.

Equalizer allows the listener to correct deficiencies in the linearity of either his speaker system alone, or the combination of his speaker system and his living room.
