I'm fairly new to electronics and I didn't know where else to ask this. I was wondering, I noticed that most electronic devices, well, pretty much anything you plug in is grounded by the 3rd prong on the outlet.
However some new audio equipment like mixers and record players still have the grounding wire that you have to ground by hand. Does anyone know why this is?

Theloniouszen,
WELCOME TO THE COPPER FORUM!
Ok I will try, most items generally have the 3 prong plugs designed for the Newer houses with 3 wire electricial wire.
While the equipment that uses more power comes with the extra Wire so you can attach it to the Screw in the Cover Plate (Assuming that will give you a ground) for the houses / business's that still have/use the older 2 wire system to the outlet.

Much of the home audio equipment has just 2 prongs. Guess they were concerned with possible ground loops? |

See what do you mean by possible ground loops? The only explanation I can think of is that since any RF interference from grounding could possibly affect the audio output of this equipment (I'm talking all the way up to top end turntables, DJ mixers, etc.) it would be better in some fashion to ground locally as opposed to through the outlet. And I don't understand why. |
