What is the signal path -- the red line?

I know, I know why the flame has begun!

Because at least 2 definitions of a signal path exist:

1. First one, is a "red line" for technicians, to understand how to read the schematic: where the signal come from, how it goes through stages, and so on, to help them to troubleshoot the device.
2. Second one, for those who is concerned in which element passes signal current, and adds own distortions due to own non-linearities.

However, 1. and 2. are totally different things.

But strictly speaking, In short: a signal path is any path through which a signal currents flow, including parasitic capacitances between cathodes and filaments, between wires and a chassis, etc...

So, like when you design a dress for a person with obesity disorder, you should ask where he/she wants to place a belt, defining what is in the signal path you always have to choose precision with which you are going to place "a belt". What is above the belt is "In the signal path", what is below the belt is not "in the signal path".



But where to put the belt, really?

Hello SY,
in the headline you asked:
What is the signal path—the red line?

In this forum of course not because most of the users here have a commercial interest.
Those who want to sell some Voodoo components tell you something like:
The signal is manifested in almost every part of the circuit .
Suggests signal path is in every part of the circuit. e.g.
#70
Therefore you have to paint the circuit red, hi hi. This is a technical forum rule and users have to accept it!
I don't like this Voodoo and it looks like this forum is more by-audio than diy-audio , isn't it? 😉 fan club forum

PS: I know that you want to 'rescue' your friends but this is not a good thing to split and edit a thread the way you did it.

Think you mean "buy - audio than diy - audio"
