Minijack to banana

Post by Ekofisk » Sat Mar 06, 2010 6:56 pm

Hey,

I am finishing up my Blacet DAD kit as we speak.

However, I am making it banana and not minijack.
When omitting the board mounted jacks, I have to solder in a couple of wires. I am fairly new to all this, and was wondering which bit I need to worry about.
The minijack has points for C, T, S and Jx (where x is a number).
I am assuming C is (common)ground, and should therefore be ignored.
S is sleeve I reckon?
T is tip?
As far as I can tell, the only point in contact with anything else (when ignoring ground) is T (tip). Would this be correct?
Just wiring a single wire from the bananajack to the T?

If so, what is the point of the Jx points?

Thanks!

"Jx" is just the jack number from the circuit diagram. J4, for example is the unattenuated output jack.

Looking at the board diagram, your assumptions are partially correct. C is common, T is tip however I think S is more likely to be the switched connection in the minijack. In all cases on this circuit, the switching function of the jack is not used so you can just connect the T pad on the board your banana jacks.

S is for switch, of course!

Thanks for clearing this up!

No problemo.

Don't forget to post photos of your finished bananafied module when you're finished!
