Dedicated circuits

Current doesn't always go up when voltage goes down, it's a little more complicated than that.

I agree with your statement, and my explanation of it probably wasn’t as specific as it could have been, but I didn’t want to get too crazy with theories, formulas and examples. Anyone is free to supply some if they wish.

That is true. For AC induction type motors if voltage goes down due to Line voltage drop, current go up.

Not so for audio equipment power transformers. If voltage drops so can/does current as well as wattage, (VA)... In the case of a power amplifier lower wattage, lower power...

Another question sort of related to the dedicated circuit topic:

either here or on AA I once read something to the effect that the class D of most powered  subs would "dirty up" the power for whatever other audio component was on the same circuit.  I apologize if I am misquoting this, this is a rather foggy subject for me.

So my questions are:  is there any truth to that, and if so, I guess that means your sub should be out there on it's own island?

I am currently running my amp on one circuit, my pre and my CD player on another circuit, and due to what I typed above being stuck in a cloudy recess of my brain, I have my sub on it's own circuit. . . .

Thank you.
