Any chance to see the images again?

I included plans for a 3-wire battery box (avoid distortion, but still allow battery power) in another thread:

Thank you.

I think I need to save these pics before they go away. Seems like they can't stay...

I have the sp cmc 8 and am in the process of attaching the mini xlr connectors.  i just cut off the stereo mini plug and noticed that the wires inside my cable are different then what I'm reading they should be.  I have one red (not two) one white and the shield.  I'm assuming that the white is yellow and there will be no problems.   

Does it not matter that the wires I read are double are singe on mine?  And also is the white wire in place of the yellow.

Thanks

You've probably got the "ES943" version, which is a lav mic, so maybe a thinner cable.  The "ES933" is the hanging mic version, with a thicker cable (I think).

OK, I'm 99% sure that red is positive and white is the same as yellow, but I can't promise anything.  I guess try it and see if it works.  You could phone Audio Technica service and ask too.  Sorry I can't help more...

Hey, do you remember how they were wired by SP?  The miniplug has L, R and shield.  I can never remember what is L or R, but if red wires were connected to the L and R and whites and shields were connected to ground, then we know that Red is positive, and White is audio (equal to the Yellow in my drawing).

Oh yeah, one wire instead of two is fine.  I'm thinking they use two for reliability (long runs, mics hanging by their cables).

Please let us know how you make out.  We need more "3-wire" people out there...

I may be being really dense here but what do the phantom power modules actually do? If the mics can only handle a maximum of 9V are they just taking the 48V phantom power and stepping it down to 9V (with a 3 wire powering design)?
If so then I might as well make a 3 wire battery box as per poorlyconditioned and save myself some cash

Phantom power modules do two things: They give a low voltage (3 to 9V) to the electret elements, in 3-wire configuration.  But also they provide a low impedance balanced output, using a transformer, or some transistor circuit.  If you're doing long runs and/or you need to connect to an XLR mixer input, you want the phantom power.  However, for us tapirs, we're probably running from our hat to our pocket, and we're probably running unbalanced lines anyway, so the batt. box is fine.

That said, I must admit that I love the convenience of plugging my AT853Rx XLR connectors into my UA5, turning on phantom power, and letting it roll.  So, for open taping I would prefer the Phantom power, but for stealth, or for saving money!, batteries are the way to go.

So the results are in.  The white wire does take the yellow wires place.  But I did have problems with one channel cutting out.  I noticed the wires were extremely thin and I would bet that this has something to do with it.  I know it is becuse of a bad connecton but if the wires were thicker (as in the at853 version) that it would be much easier to get and hold a good connection.  The thin wires are very fragile.  I wish I got the at853's, I'm using the caps for them anyway.

do you have any of the 943 caps or are you using all at583 caps?
