SL4K-E01

PriceFrom €309.84

  • The SL4K-E01 preamp is a DIY audio kit that recreates the classic preamp design used in a 4000E desk. It features the original Jensen input transformer for a balanced input signal and a preamp section based on the E01 schematics. The two op amps used for gain provide excellent audio performance. Thanks to the input transformer, the preamp has its own unique characteristic sound that makes it stand out from other preamp designs.

     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, which can be selected Pre or Post Fader. The 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.
