USB-Powered High Precision Hi-Fi Phono Preamp

Abstract: A quad, low-noise, op amp and LDO are used to build a stereo preamp with RIAA equalization to allow
converting signals from a record player (phonograph) to a linear output for digitizing by computer sound cards
etc.


A phono preamp is needed for preamplifying and equalizing the analog output of the good old record player. The
former hi-fi amplifiers or stereos included a phono input, but at this time it is not very common because the CD
player has a linear output and doesn't need linearization. If you still want t……
