Thanks for your feedback MJ; that's been very thought provoking and helped me pull focus on the task
If you're used to soldering small stuff, you'll be fine with the LEMOs
Now, not wishing to defocus you, but just to add a few practical details:
Firstly, I see that I mistakenly mentioned "LEMO 0B" size connectors. Just to avoid confusion, I meant to have said that the ones used by Zaxcom, Sennheiser, (Shure?) for radio-mics are actually the "00" size screw-on, with 3 or 4 pins & internal links. These are probably more suitable for hanging onto the fragile cables of your DPAs. Just to add to the confusion, I just looked up the Lectrosonics circuit & they use a TA5 plug &, again, internal links are required to get the powering correct. It's another option, cheaper & a bit easier to assemble.
But without looking up & comparing all of the manufacturers' specs, I can't say for certain whether any of them are directly interchangeable, even if they use the same connector. I think it's part of tying you into their system! So if you're likely to ever want to use your mics with a bodypack transmitter, you probably need to decide which brand and model you might use & go from there.
But back to LEMOs
Depending on your supplier & how you buy the connectors, you'll probably have a limited choice. But the part numbering system allows you to specify every last detail.
In case you haven't got it, here's a useful pdf with great internal links to the appropriate sections to help you compile the part number:
https://www.lemo.com/catalog/ROW/UK_English/unipole_multipole.pdfI actually prefer the push/pull latching arrangement to the screw-on variety, and with 2 pins, you know where you are. So for the plug on each of the DPA leads, I'd suggest:
FGG.00.302.CLAD.22.Z
That's: push/pull plug size 00, chromed brass shell, 2 pin male, solder connection, 1.4-2.2mm cable collet, strain relief backnut.
The rubber strain relief boot will be:
GMA.00.------ (you'll have to select the options)
Then you'll need the matching sockets & cables to go to your 5pin XLR.
Mogami 3031 mini balanced cable is probably a good choice as it has a tough braided* screen & is about 3mm overall dia. I've used Belden 1804A mini starquad, which is a similar size but 4 core & overkill for an unbalanced connection, (but I have a length of it bought years ago for something...). Each pin (signal & ground) can then have its own wire & the screen is separate & connected only to the shells & finally grounded at the preamp (or in your 5 pin XLR). One of the minor quirks of the LEMOs is that there's no separate terminal for the screen. The trick is to fold a short length of the braid back on itself so that it's on the outside of the cable sheath, (a bit like turning down the cuff of an overly long rubber glove), then push the whole lot into the clamping collet before tightening down. This means that the collet needs to be of a slightly larger diameter than the nominal cable sheath. Having a few spare collets of differing sizes doesn't hurt...
Ahh... The quirks of LEMOS. But, overall, they're very well thought out connectors: they just impose a bit of rigour on the assembly process!
* I'm sounding like a cable geek here, but the real advantage of braided screen over spiral lapped is that if you tug on the cable (which happens) it tightens on the inner cores and hangs together. A lap screen cable tends to stretch & twist as the spiral wants to unwind. This causes kinks in the cable & also puts stress on the tiny internal wires.
Phew!
Now you know why these pro radiomics cost so much - it's the hours that go into choosing the connectors! (then the time taken to wire them, & not forgetting the cost of the LEMOs themselves...)
Good luck with it all:)
