Disconnect would be cool.

Thinking aloud here-
I'm now considering revising the OMT snake to include a single multi-pin disconnect for all 8 lines at both the mic end (adjacent to the stud) and at the recorder end, with short fan-outs to the mics and to the recorder inputs.  Would probably retain the individual cables within the snake and terminate to an multi pin Amphenol connector or something like that.  Something more robust and a better form factor than a D-sub connector.  We use Amphenols for connecting control-pendants on hydraulic boating equipment we build at work and they provide a robust connection.  Just need to keep the size (and weight) of of the disconnect at the aloft mic-hub/stud end small enough.

I can't picture the connector you're describing.  Could you link an example?

I'd need 10+ pins minimum (7 two wire mics + 1 balanced).  Here are some examples. Generally round with metal housing.  Will mock it up first it to see if a rectangular form connector works better.

There is always LEMO:  https://intra28.lemo.com/PartSearch?app=medical&mat=metal&ref=&lang=en

^ yeah, may be a better option as it would probably make for a more compact in-line connection.  I just wonder how fidgety is soldering 8 cables to 10 pins in one of them.

It's pretty easy because you solder the wires to the pins first, then insert the pins into the connector. Just make sure you order the proper pin extraction tool from LEMO if you go that route. This also makes re-termination very easy.

That sounds more easily managed, thx.

You can sorta see how this worked out.  I need to make a few more short jumpers and will fashion a proper mount for the cable head end.
