Hi,

1st of all, i'd like to know the exact connections inside a jack plug :

For a stereo jack :
An externally hosted image should be here but it was not working when we last tested it.


the extremity is the left signal
the middle is the right one
then it's ground (the bigger one)

Is this correct ?:confused:


For a mono jack :
the extremity is the hot point
then the bigger part is the ground ?

Correct as well ?:confused:

An externally hosted image should be here but it was not working when we last tested it.



If so, when you connect a mono (male) plug inside a stereo (female) one, is there a risk to short-circuit the right channel of the female plug (through the common ground of the male plug) ?

I am designing a headphone amp so this has to be taken into account :D
 
Hi Johnix
Stereo: correct
Mono: correct
Yes, you will ground your right signal. This is not correct but not harmful to the headphones or amp.

Edit: It's harmless at line level, which isn't your case. You will short your amps right output and that's not good.
