Wiring audio out jack.

[radfaraf]

I'm using a 3.5mm audio jack for my audio out and need help wiring it. I have a diagram of the one I have
http://rocky.digikey.com/WebLib/CUI%20Inc/Web%20data/SJ-3535.pdf
There are 5 possible connectors. From that diagram I figured which connector is which number on my audio jack but do I do not know where go from there. I don't know how to read the part of the diagram labeled schematic in the top left of the pdf, it shows some diagram along with the 5 connectors and connect 1 is labeled S, connector 2 is labeled R, and connector 5 is labled T. What does S, R, and T stand for ?

From the schematic of the mini-synth. It appears I need two connections only? One where C22, R23 which are in series are connected to something and another for ground. Is it as simple as connecting ground to what is labeled 1 on the audio jack diagram and 2 to C22,R23?

I'll give it a shot this is what SRT stand for:

Sleeve=ground
Ring=usually for black wire on battery to turn an effect on/off when the
input jack is put in
Tip=Input/output of circuit

with that said you should only have to(like you said) have 2 connections
ground to Sleeve and output to Tip

good luck hope it helps

Thanks I got it wired that way. Can't test it yet as I have to do a lot more wiring still. Here's a pic of what I wired so far.

Your connector is stereo, where mono was specified in the schematics. This is not a problem though.

When you connect 1 from the schematic to (1 S) of the connector and 2 from the schematic to both (2 R) and (5 T) it will work for both mono and stereo cables.

Conector pins 3 and 4 are switched. When the plug is not inserted 3 will be conected to 2 and 4 will be connected to 5. Both conections will break when the plug is inserted.

This switching capability can be useful for patch plugs, where you can then make a default conection by using the switches which will then be broken when you insert a patch cable.

When using the 3.5 mm stuff this is always a bit fragile and tends to become unreliable with time, best to use the big ones for reliability.

I see, I got 1/4" jacks too but I don't have much use for them right now as I have nothing with a connector that big.
