Hi,
The circuit showed in the photo it's from an EQ, thepot simpy controls the cut or boost in the center frequency, in this case 650hz.
From what I can understand by analyzing the circuit to change the center frequency is just a matter of changing the values of resistors R12 and R14. Higher Values will lower the Frequency.
Can you please help me on how could I calculate this values?
let's imagine I would like to have 250hz has the center frequency, what would be the values for R12 and R14?
Thank you
