Anyone got any good photos or drawings of the wiring for an input jack with two quarter inch and two speakon inputs? I'm building a Jack 212 and went with that option for the Jack plate, but I'm just unsure about how to wire that up.


Thanks.

Make eight pigtails all about 6 inches(12mm) in length. Strip and tin each end. Attach an end of the pigtail to a Speakon or jack post. Do the same for the other seven.
Now, all the +1 and the centre post of the jacks, get soldered together at the other ends of those pigtails. All the -1 and outside jack posts are soldered together.
From there, run a length of wire to the driver or cross-over.

Wow, awesome. Thanks for the clear explanation. That should be no trouble at all.


Thanks.

Your welcome.

What do you guys do to make the 1/4" inputs airtight?

Not install them.

I remember someone on the forum said ear plugs work to seal the jacks.

Thanks. I guess when the cable's plugged in I don't need to worry about it and i can seal the other one up with and ear plug.

If you absolutely need 1/4" use the Neutrik Speakon combo jacks.

Just be aware that the combo jacks are not air-tight. They claim to be, but they are not.

They are if you seal the back of them with hot-melt glue after the wires are soldered on. 1/4" doesn't offer that option. Even without doing that they're almost airtight.

Couldn't you also used sealed 1/4" jacks? They're most common on basses, and aren't cheap.

That.
Or, if you are cheap, like me, and in a 3rd world country, like me, you could cut an aluminum can (ie: spray deodorants) with an old pair of scissors to make a small cup, run the cables through a small hole in the bottom, apply plenty of glue, clamp in place, leave overnight to solidify, hot plastic gun the whole mess just to be sure. Hey, it worked!

DIY to the bone!
