Wiring questions...I need some help

[drummerdan]

I am finishing up on my e-snare project and I need to know some wiring tips. How do I wire the 2 piezos (dual trigger) to the jack? Since there are 2 piezos, I don't know the wiring configuration. Anyone know this?

Thanks.

hmmm...that is a TRS (Tip Ring Sleeve) jack. three wires. I think the center wire would to to the tip, and the other to the sleeve (not sure about the ring).

someone else might know. If you are doing two sensors, then the center of one goes to the Tip, the center of the other to the Ring, and both commons to the sleeve.

Dan,
Try this site it shows a diagram for wiring two piezos.

Hope this helps.

Not trying to seem dense here, and I appreciate the responses thus far, but I am still not getting anywhere.

The stereo and mono jacks I am using are just like the one posted by Drummerdan in the referenced thread.

However, I am not getting the "ring, sleeve, tip" thing at all.

I just see three potential solder points, and I would assume two of them (on the stereo jack) are for the live wires and the remaining terminal is where the grounds (black wires?) from both piezos would be soldered. Two of the solder points look similar (again, on the stereo jack, not the mono) and one has more of a square type appearance, which I would assume would be to differentiate pos/neg.

I just need to know

1) which positive lead from each piezo goes to which lead on the jack (which would also tell me which lead to leave clear for the ground wires)

and

2) if there is any difference between the two sides of the speaker wires that I will be using to extend the lengths of the piezos and if so, which side should go to red and which to black (ground)..

thanks

One positive to the tip from main trigger, one, from from the rim trigger, to the "ring". both grounds go to the sleeve. Best way to help visualize it. You got the female connector like above? Take a male 1/4. doesn't even have to be stereo (tip/ring/sleeve). Plug them together. Note which solder point the tip contacts, note which solder point the ring (which is about 1/4 inch up the tip of the male and will be "separated" by very small insulation material), and the last one is the sleeve.
If you sit and 'trace' the metal parts of the above photo, you can also see which solder point goes where. Also, you got a circuit tester? You can touch one probe to the solder point and then probe the others to see which one it makes connection to.

Jon,

After I found this diagram, it all made sense. Look it over and let me know if you have any questions.
