Gearshift

Gearshift exists is to give you a one-size-fits-all solution for translating between different CV requirements like 0v to 8v, -5v to +5v, -3v to 5v, etc. You set the jumpers on the back to raise or lower by 1,2,3,4, or 5 volts and that's that.

You can find the manual for Gearshift here!
