This circuit makes the RIAA equalization for signals obtained from a turntable for signal recovery in other media. At the input of this circuit we will plugl one turntables for vinyl records retrieval and output is plugued to other media such as PCs, MP3, etc. They can use two operational amplifiers 741 or the double version of this component as the MC4136 or MC1448. Consumption is low, but the power supply must have excellent filtration. The circuit is adapted from a 1993 Popular Electronics, with amendments enabling their assembly today. Signal input cables and output cables must be shielded.
