half normalling solder TT patchbay, help?

Hi guys need some help. I need to half normal two channels on my tt patchbay. I have no idea how to connect the wiring to do this. I've searched through google and found images like the one I have attached however I have no idea how to read it. I just need a basic image, actual photo from the back of a connector half normalled so I can solder the correct wires to the correct terminals.

Any help would be greatly appreciated.

Every manufacturer makes the interrupted TRS jacks a bit different.

Look at the diagram you have there and figure out what solder tabs correspond to which parts shown there.

There are tabs which contact the plug, when inserted and tabs that break contact from those when the plug is inserted.

...or you could hire someone to do it at a local electronics repair.

As tINY says, there is no generic answer to your question. It depends on exactly what you are dealing with. To answer your question to your satisfaction would require either a really good photo of the jack stack (from the side so we can see all the leaves), or else the identity (make, model#) so we could look up the same info from the mfg's website.

To people who have done it before, it is obvious upon inspection, but that doesn't help people with no previous experience tracing it out.

What kind of documentation do you have now? Are the connector terminals labeled in any way?

It's all good man I was able to find some documentation on the audio accessories website. Finally figured it out. :-)
