There are people out there still using ground lifts for AC.. Not a good idea.. Use a isolation transformers for your inputs from the house console with a pin 1 lift switch on them and you will never have to lift a AC ground again.
Chris,
By "use a isolation transformers for your inputs from the house console..." you are referring to preventing ground loops from plugging a rig into the console, correct?
Wouldn't you still need to lift the AC ground from the quad or whever you plug in your power conditioner/surge protector if you need AC power for a recorder/computer/external pre-amp, etc.?
I am still learning all this electrical stuff, so I am eager to see your response. It has been my experience in a lot of smaller clubs that the problem originated from plugging in to the AC outlet of a quad/power strip that is not adequately wired, and that no issues occured when plugging in to the console while running my recording rig on battery power.
