This circuit allows you to equlize the audio signals in ten band. It uses low cost op-amps to form a professional equalizer circuit. The heart of the design is a classical band-pass active filter. The U11 acts as an attenuator to prepare the signal level for equlizing. The U13 acts as a final voltage amplifier to deliver the equlized audio signals to the next stage. The VCC is in range of +12 ~ +15 VDC and The VDD is in range of -12 ~ -15 VDC respectively.
