Phono input
« on: June 17, 2020, 11:37:40 AM »

Request for a switch to reverse polarity for the single LP

Request  to modify via software the gain of the first stage

Request  to modify the complete RIAA to an incomplete  RIAA without the 75μS (2122Hz) turnover frequency

Many thanks

Alberto

Thanks Alberto

We can add those features and even have a user customizable RIAA curve as well as the industry standard ones ;)

Ok got to spend some time updating the firmware so have incorporated the requested mods for the phono preamp.
