To clarify a little;
"Balanced" audio cables impose the audio voltage across the two "inner" wires, with the shield connected to chassis ground and not contributing to the signal.
(In fact, there is a standard practice to cut the connection to chassis ground at one end of the cable; this basically "extends the shield" from one piece of grounded gear but does not allow a ground loop.)
"Unbalanced," the kind most seen in consumer gear, omits the shield and ties the "sleeve" to signal ground.
Balanced interconnects are superior in that the signal is the difference between two leads (not one and a ground reference). Thus, most extraneous EM that gets into the signal leads will occur across both of them equally and be canceled out at the input transformer. |

Again, you are skirting the fact that you originally claimed that not "matching the impedance" would cause amplifier damage. In a solid state amplifier of modern design, it is simply impossible to match the load impedance to the final amplifier output impedance. Thus, your statement was wrong.
Do you disagree? |

Let me put it another way that clearly proves my point.
Lets say your washing machine leaks water from the pump and this allows current to travel to ground. What happenes to the grounded motherboard? Remember, its circuitry is highly sensitive to even static electricity!
Thats why the motherboards actual circuitry is carefully isolated from any earth grounding. |

Its not a nuclear reactor, but it is undergoing a nuclear reaction. Technically, a reactor purposely regulates the reaction. Now tell us why these watches are no longer marketed!
I remember when I was a youngster buying superballs that glowed in the dark out of a bubblegum machine, SOme kids actually believed they could aquire superhuman powers by EATING the superballs!
Just goes to show how stupid some humans can be , botht those who marketed the toys and those who ate them. Perosnally, I can forgive the children, but not the marketers.

Oh, and lest we forget -- the reason we got onto this subject of motherboard grounding was the contention that a battery would discharge if the negative terminal was earthed.
The box I took apart and photographed for your pleasure has maintained the charge on it's back-battery for the ten years I have owned it. For over a year it has sat plugged in and connected to ground (though powered down).
I don't need another test to prove to my satisfaction that a battery does not discharge when earthed. |
