I have a 4 way adapter socket which serves power to 4 hi-fi seperates. I notice that when they are connected to the socket and the main switch is in the on position that the hifi seperates have a almost inaudible hum despite being turned off.

I don't mean appliances that are on standby like video recorders and TVs. I mean things that are really turned off but still have electrons flowing through a turned on socket...not a turned on appliance.

Many modern appliances have electronic circuits that are "on" and consume a small amount of power even when they are "turned off". This probably includes your hi-fi. This is true of any appliance that can be turned on with a remote control, can be set to "turn on" at a particular time, that uses an electronic "on switch" instead of a mechanical on switch, or incorporates a clock.
The amount of power involved is usually very small, and the danger of it "turning on by itself" in a dangerous way is also small.

Those with the instant on feature consume a small amound of power (10-40 watts) which adds up with everyone wanting instant on for their TV and hi-fi. Only unplugging will stop that consumption. But you still have your clock radio sucking up some juice so you will never have a zero power consumption in your house.

Everything that is plugged in still consumes some power, even if it is turned off. It is still brining in power.

It needs to be on for the remote control to work.
