DPA 4061 and 6061 on Lectro SM & SMA hiss after high spl from client hitting mic.

Need some tech advice! Pop and hiss on DPA 40/6061!

For reference I am using a lectrosonics SMA and SM tx going to a UCR 411a. The LAV mics are a DPA 40/6061 wired for Ta5F. I use a 1k ohm resistor in the wiring as I do them myself to save some $$ and the 3k-4k makes them just a bit to soft for standard speaking.
The client we worked with today had a habit of cupping their hands and putting them to her chest. Whenever this happens a loud pop occurs, and then the audio becomes full of hiss. I can unplug the mic, then plug it back in or turn off the tx and it would sound fine after.
But has damaged occurred to my DPA lavs at this point? It sounds like they were overloaded potentially? Looking to hear your thoughts and how I can prevent this in the future?
Here is a clip of exactly what happened:

Oh that is curious. After reading your description I thought it would be the limiter, but now it’s a limiter that never opens anymore. 
So I‘m not clear yet what happens now. The interview is over and you rebooted your transmitter and everything sounds fine again? Or does this recur?

That is crazy, never heard that before.  I'm very interested in this, I hope it gets solved.  Did it happen with more than one mic?  It does kind of sound like resistor hiss, but I can't imagine this being that since they recover and sound normal again.  It may have something to do with those resistors?  Are you trying to simply add a dB pad? Maybe remove the resistor and see if it still happens. (Calling John Blankenship!)

Yep, after reboot it sounds fine. I went ahead and re-terminated the pin without the resistor. The issue was still present. After hours upon hours of experimenting, I found my issue. In the pictures I took before re-soldering the connectors entirely, I saw that the jumper between pins 3 and 4 were making contact with an exposed portion of the shield in pin 1.

 

After shrink tubing the shield and wiring both the 4061 and 6061 with no chance of the shield and jumper touching, the problem went away.

 

Basically this has turned into a PSA post on doing proper soldering and cable management.

Haha!  Nice.  I once had an issue with a guitar amp where everything was working great, but when I installed the chassis into the cabinet, the sound disappeared. I took it in and out and couldn't find any cause. Then I looked at where the chassis screws went and noticed another wire in close proximity to one of the holes. Turns out the screw was grounding a signal wire and I had to reroute the wire and repair the break in its insulation.  Glad it's solved
