I think if the equipment is turned off, it’s O.K. to unplug at equipment end. To be extra sure, find which circuit breaker provides power and trip it before unplugging. Some equipment these days remain active, somewhat, even when turned off. Not and issue, IMO.
Unplugging power cords from amps/ pre amps
This might be a stupid question but when there is a thunderstorm lightning storm I used to unplug my power cords from the outlet but now I can’t do that because of a lot of things in the way to reach my plugs from the outlets. I want to know if it is ok to unplug my amps / pre / cdp from the female end that goes to my equipment and then replugging them back after. Of course the units are off when unplugging / plugging them back. Ty.
