I bought many products for my new rack set up but they have on and ground lift. Wich one should I choose and why?
 
If it buzzes, try the ground lift on ONE piece of gear (not all of them).
The ground lift prevents/eliminates/cures ground loops.
Ground loops can happen when many pieces of gear get plugged in to each other.
 
What the switch is actually doing is tying signal ground (on the PCB) to the chassis ...
 
"Typically" you want to lift the ground on all but one piece and that's usually your power amp...again "typically"
