Determining the left/right just by looking at the cable

post #1 of 5
Thread Starter 

Hey guys, I have a faulty connector, I'm about to chop her off and put a new one on, but then I stopped and realised - 

 

Hang on, which is left, right and ground?


What's the most obvious way to tell? Is there a universal standard for this?

 

 

 

 

The wire on the left has a stripe. The other two have no indicating marks.

TRS jacks are typically wired as:

 

Tip = Left

 

Ring = Right

 

Sleeve = Common Ground

 

You can always test continuity with a digital Ohm meter.

Yup  - Thanks! This much I've gathered from my cable making. I tried to apply the same theory here, then realised that all I have is basically three wires - what's the best way to distinguish which one is tip, which is ring, which is sleeve?

Continuity check.

All the headphone cables I have seen have the right channel marked in Stax it is the white dashed line on it. Put the headphones on--- holding the plug and using an ANALOG MM -- one lead to the sleeve--other leg onto tip--listen -to which side makes a click. Do same with ring[still keeping one lead on sleeve] and listen for click. Problem solved.
