By the way, Sennheiser has lots of experience with protection of the diaphragm.
The MKE2 lav mic has a protective "dual diaphragm" in front.If you buy the raw KE4 capsule, it does not.
If you've got a mic (exposed 4.5mm dia capsule), look right into the hole.Shine a light in there and look at the reflection.  if you see gold you've got a raw capsule, if you see silver you've probably got a second diaphragm in there.
Sennheiser insiders may know more about this.
IMO the KE4 sound a little better and more clear than the MKE2.I've got both in my mic cache.

I used the mics tonight but it turned out sounding bad. Almost like clipping but it was set to peak at ~-9db. Maybe the CA9100 supplied too much power?

I was afraid of that. My tests show that they can run line in from a battery box. Did you try the "0" setting on the 9100? That would just make it a battery box without gain.

I'm planning to wire my first pair of these to mono mini XLRs.  Is there any reason I couldn't use the AT8531 power modules with these mics?

My first run with them was this morning. I cannot say enough good about what I've briefly heard of them. I let Sarge clamp the cans on, and she commented on how clear it sounded.
I record quite frequently in this room; noisy HVAC is my worst comment about it. Its a nice sounding room, just noisy.
I ran Gude Head as both Senn. protocol binaural, and, with the new MKE2 pair on Gudes head, as HRTF stereo. I also ran the cm3 pair as XY_90º as a "control copy", in case the building got nuked, and Gude exploded, the old folks started into slam dancing, or whatever.
All acoustic, except the vocalist.

If someone can help me with how I should wire these I'd appreciate it.  For now, I want to wire each mic to its own mini XLR.  Here's the info from the other thread:

I would put the red on pin 2 and put the blue and shield on 1 or 3 then put a jumper between 1 and 3. Remember the blue and shield are shorted at the capsule so there's no advantage to running an xlr except for a sturdier connector.

Does that sound accurate?  If so, how do I put a jumper between 1 and 3?  I've never done that before.

What were you using to power the mics?

I used my DPA MMA6000 preamp, which I converted years ago to handle a 1/8" stereo input and, the microdots as well.

The mics are definitely sensitive.  This might be an issue to loud music. Perhaps that 4.7 mod might be necessary? (sorry, I don't even know what that mod is/does).  But, the mics are definitely more sensitive than my 4060 pair.
Yesterday,... I've recorded that ensemble for nearly twenty years now.  I've recorded in that room extensively.
With my DPA4060 pair, I needed to add on the lines of 18dB gain.  Yesterday, the preamp was mostly acting as a battery box, with little added gain (perhaps 2dB+ added?).

Does that sound accurate?  If so, how do I put a jumper between 1 and 3?  I've never done that before.

I would use two wire shielded cable (lets say the wires in your cable are red, blue and shield)

Connector end
1 blue
2 red
3 shield

Connection to mic
red to red
blue and shield tied together to blue and shield

Or you could just wire them straight through
red to red to pin 2
blue to blue to pin 1
shield to shield to pin 3

then take a very small piece of wire, a half inch or so, barely strip it on both ends and tin it, then after you have connected your cable to connector you add the short piece between the connector cups of 1 and 3 on the connector. Be careful not to unsolder the existing connections while you get the jumper in there and have the solder flowing. If you have a little extra wire from the jumper you can prob make it fit inside the connector housing easily enough. This is easier in a larger connector like an XLR but it's doable in a TA3. When doing smaller connectors I gently clamp them in the jaws of a vice grip to hold them steady. Don't get too crazy with the solder it could overflow the cup and short the connections.

This is assuming your device you are connecting to is pin 2 +, pin 1 -, pin 3 ground.

Why are you using mini XLR? Do you have an existing preamp that has those inputs?

I added a live sample of acoustic music to this folder:
https://archive.org/details/test2.horizontal
Find: MøKE2_Live-Sample

What is it?
You're totally going to recognize the melody. If you don't, well,...
This is a short portion sample of Thomas Jeffersons presidential campaign song from the late 1700's.  The lyrics were originally written for this campaign song, and later "converted" to another song.

For the more secure connection, and to try using these with the AT8531 power modules.

Thanks for the info!

Well, my first attempt was a failure.  I'm not sure where I went wrong but it didn't work.

Those AT power modules are three wire, red, yellow and bare (sink). I was under the impression you can't use them with two wire mics. I hope I'm wrong, because I have a pair of them and it would be great to finally use them for something.

I've included a schematic I found.

Yeah I think you're right. I made a quick stereo mini plug Y cable and it worked with a CA9200!
