[sdiy] stereo output questions.....

[John Mahoney]

Here are 2 ways to carry stereo signals:

1) A pair of 2-conductor cables, one for L and one for R. Each cable 
has a hot (signal) line and a ground.
2) One 3-conductor cable, with a hot line for L, a hot for R, and a 
common ground.

3-conductor stereo cables typically have TRS connectors. Example: headphones.

However, TRS connectors are also used for mono, balanced cabling, 
which also has 3 wires (signal+, signal-, and ground).

XLR connectors can carry stereo signals but they are usually used for 
balanced mono.

When you say "stereo not TRS", do you mean separate Left and Right 
cables instead of one stereo cable?
