Link Audio Design 512 Preamp
This Preamp is a recreation of a Classic Preamp design of a 512 Preamp. The preamp section is based on the 512 schematics and uses a 1:10 Transformer for a balanced Input Signal. The Preamp design itself uses one Op Amp for Gain. Add your DOA of your own choice ( NOT INCLUDED IN THE KIT) Due to the Input Transformer the Preamp has its own unique characteristic sound that could not be achieved with only semiconductors based Preamps. 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.
