8x Mixing Attenuverter

Octaverter was built to handle attenuation for my entire system. This project went through a record number of revisions due to my indecisiveness and I eventually got bored of working on the same thing all the time. Files are available for this module if you are interested in building it or making your own design.



  • 8 independent attenuverters

  • Each output is normalled to the one below it if no cable is inserted

  • Each input is normalled to 5V if no cable is inserted

  • Bi-color LEDs to help visualize the output

  • 12hp



  • Move actual circuitry to separate daughter board

  • Remove empty space between jacks and potentiometers

  • Find satisfactory implementation for variable gain
