I recently had just such a need and ran into some difficulties, so I decided to build an Inverse RIAA Network. This simple passive circuit adapts both the signal amplitude and equalisation curve to satisfy the phono preamp input requirements. It works both for Moving Magnet (MM) and Moving Coil (MC) levels, and the PCB makes it really simple to implement. Two really important sources of information used in the making of this video: ➠➠ https://sound-au.com/p80-Inverse-RIAA.pdf ➠➠ https://www.ovationhifidelity.com/wp-content/uploads/2018/04/Accurate-Inverse-RIAA.pdf
