ground lift

icon HOME icon DOCUMENTATION LIST icon

After testing the CHRT Synth on many stages and in rehearsal rooms, often with dodgy earthing conditions, I came to a conclusion that Ground-Lift circuit is of no practical use. Should anyone encounter a hum problem due to earthing conditions, it is best solved with any DI box. Such solution is also much clearer to electrical safety authorities. From rev.2.0, the Ground Lift circuitry and swich is omitted and therefore this page is not relevant.
