5 bands Stereo graphic Equalizer circuit diagram

This stereo equalizer circuit is built with TL072 operational amplifier and performs an amplification or attenuation of each frequency range with around 13dB.
When all five potentiometers P1 + P5 positions are settled on the middle tier will get a virtual frequency response (0 dB). The entire controlled domain by this circuit is about 33 dB.
The signal / noise is 90 dB for an input signal with an amplitude of 1 V.
Resistance coils and resistors in series total in each feedback loop must be maintained to 680 ohms.
