F. Ground loop protection (GROUND LIFT)

FADED-50 amplifier is equipped with GROUND LIFT function, which

can be activated/deactivated by switch n.19.

The meaning of this function is to disconnect the ground

loop which most likely comes from using the effect loop (different

grounding points) to eliminate disturbing hum noise.

The GROUND LIFT function disconnects this disturbing

ground loop together with preserving all safety measures.

There is no need to use this function if disturbing hum is not

present.

Please do not mistake common signal noise/hum of the

amplifier itself or noise of single coil guitar pickup with noise caused

by GROUND LOOP. Identifying the ground loop:

Compare the hum noise of amplifier without (only guitar,

amplifier and speaker) and with respective effects connected to the

effect loop or directly to the amplifier input.
