Unity Summer - patch programmable unity gain mixer


  • Eurorack power cable and M3 screws are included
  • DC-coupled mixer with dense functionality
  • Two identical circuits (top and bottom), each with a 3-input and 2-input mixer
  • The 3-input mixer has only an in-phase (non-inverted) output
  • The 3-input mixer's output is normalled in to the 2-input mixer (if the 3-input mixer's out is used, the normal disabled)
  • The 2-input mixer has both in-phase and inverted outputs
  • If the 3-input mixer's output is not used, the circuit becomes a 5-input mixer with in-phase and inverted outputs
  • Switches on the rear of the module can pad each mixer by 6dB, allowing more headroom in the +/-12V system

*The Unity Summer is a tight fit, but we haven't found a case that the Unity Summer is too tall for.
