You want to build your own RIAA stage or change an existing? You want to use different capacitors for your platINA? Then check out our online RIAA calculator. You can simply enter the value of the capacitors you want to use and calculate the necessary values of the resistors. The calculator even recommends a parallel circuit of two E24 resistor values, that match the necessary value best.
This calculator is specifically designed for a passive/active RIAA equalization, but expect more calculators in the next time. Another feature that is planned is an online frequency response plot that shows how the filter deviates from the optimal RIAA equalization.
