PI312

PriceFrom €297.55
Excluding Sales Tax
  • The PI312 is a high-quality preamp that recreates the classic design of a 312 preamp. It uses a 1:7 transformer for a balanced input signal, ensuring that your audio is clean and clear. The preamp design features one op amp for gain, and you can add your DOA of choice (not included in the kit) for even more customization. Thanks to the input transformer, the PI312 has a unique character that sets it apart from other preamps on the market.

    The Sound of the preamp is definite and has a rough nature in Sound that works definitely in every music production. Instead of a Gain pot we are using a stepped Grayhill Switch and make this Preamp full recallable.


    The Addons of this Preamp are Peak LED and a full Meter. The Output Attentuator Fader at the End of the Preamp module gives the most flexible options to make this Preamp use in different situations. In that combination of Preamp and Fader there are already a lot of possibilities for sound colouration with the Preamp. In addition we added a variable Low and High Cut Filter, to clean up the Signal before recorded and DIYRE compatible Colour Modul Option to add another Colour to this preamp.
