Ultra Compact Attenuator

Quick Mix (QM) is named as such because this project was intended to be quick. There are no active components, just 6 pots, 11 jacks, and 5 resistors. This gets you 5 individual attenuators and with a mix output in 4hp. Although amplitude can drop rather drastically through the mix output, it is easily amplified elsewhere in the rack.



  • 5 separate attenuators

  • All channels summed to Mix output

  • Attenuation on Mix output

  • 4hp

  • Cheap as hell



  • Add reinforcement near potentiometers to prevent the module from flexing during use

  • Figure out best resistor combination for passive summing
