Default The difference between Balanced TRS and 1/4" stereo jacks?

Are these actually the same thing?

The guy at Maplin says they are, but I'm guessing that TRS works on the same principle as XLR and so would consist of a + and -, plus a ground.

I would have thought that a stereo jack isn't quote the same?

Can anyone help clear this one up for me a bit please? I've mostly worked in the digital domain, but since I've upgraded my outboard setup, just want to make sure I don't have any weak links in my signal path :\

Yes, they are one and the same thing. When used as a stereo jack, the tip and ring carry the left and right signal and the sleeve carries the common earth connection. When used as a balanced connector, the tip and ring carry the +ve and -ve phases and the sleeve carries the ground connection.

Is that just the same as balanced and unbalanced? When one has the 1 black ring on the connector (unbalanced) and one has the 2 rings on the connector (balanced)?


Scrap that, i'm think i'm on about something else.

Thanks very much Dave, I had always thought they were the same also, but read something in Wiki-Recording that made me question it. I'm no electrician, but beginning to understand that the conductors do not have pre-defined purposes as I imagined, they are more like 'blank' conduits/connections.
