WebMar 19, 2015 · A passive RIAA filter will attenuate the signal nonetheless, which is why we have the first gain stage. Then the signal won't be completely lost in the filter. What's more, the attenuation in the RIAA filter is higher as the frequency increases. Which is a very welcomed feature indeed. WebNov 28, 2015 · Inverting RIAA Network (Series-Parallel) Application This calculation applies to an RIAA impedance network that converts unequalized signal current into equalized output voltage. This includes inverting and current input stages.
