PI512
The PI512 Preamp is a faithful recreation of the classic 512 Preamp design. With a balanced input signal achieved through a 1:10 transformer, this preamp delivers pristine audio quality that captures every nuance of your sound. The preamp uses a single Op Amp for gain, and you can choose your own DOA to customize the sound to your liking (not included in the kit). Thanks to the input transformer, this preamp 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.- Shipping will be calculated depending on your location
