I took my MKE 2's out on Wednesday and they sounded great. SPL's up to ~100dB and no brickwalling. Also, my first time out with a v1 littlebox which I used to feed the mics 9v. I used the MKE's to fill in a SBD feed with audience ambience. When I have time I'll post a sample of just the mics.

Your original correspondence:
What is the SPL handling limit of the MKE 2 Elements Microphone for GoPro HERO4?

Good Day Charles
In regards to your request, we would like to provide you with the following information:
Max SPL for the element would be 142 dB at 1 hHz. the same as for the wired MKE 2 element.  The only difference is in the termination and housing.

I assume these values are when the mics are provided with the proper voltage. USB generally is 5V if I’m not mistaken, so the 2.5-3V supplied by most recorders may have lower max SPL. That said even a steep drop from 142 dB would be more than enough for most of our needs.

So you ran MKE2 @9v > Littlebox > Recorder? I'm curious as to how mine ended up brickwalled so badly with the same voltage supply. I'll have to try recording from the back of the room next time.

I don't think so. I tested it afterward with the MKE2s and it was fine with my stereo. I think it may have been that I was up too close to the speakers (3rd row or so) - I was getting as close to the source as possible to cut the chatter.

The db meter was fine for the entire show, which is why I didn't know there was a problem until it was too late. I'm not sure if it was clipping at the preamp, as I just set it and watched the show.

My source was: MKE 2 > littlebox > MixPre-6

The littlebox supplies 9.2v to the mics according to my VOM.

MKE2 elements > Zoom F1 plug in power > Beyerdynamic DT990 Pro 250 ohm headphones.
I used a thin dual shielded cable (from a Corel mic-headset), soldered to the thin mic wires, and covered that with gaffers tape.Gaffers tape visible in closeup picture.
Good for outdoor recording in high wind.

Yes, snow and very windy.Mics are sitting on ice covered driveway.
These mics sound excellent outdoors.  No problem whatsoever with very high winds.

Here is a sample of my first outing with the MKE 2's: https://drive.google.com/file/d/1uhoqvCf0-5XpMg1-V_vqtbeBPZhUrXyj/view?usp=sharing

Small, shoe box type venue with the band setup on the short side with the soundboard (and me) against the short wall. MKE's taped to a light bar. Not the ideal position (too high).

Source: MKE 2 (spaced 10") >  littlebox (running in the orange/red) > Mixpre-6

I only normalized this, converted from 24 bit to 16 bit and added fades. No EQ or compression.

With a little EQ and mixing in with the SBD feed I came up with this: http://www.timebetweenthenotes.com/audio.html#sge_2019-02

The SBD feed was mostly just vocals and acoustic guitar, so the balance is way off even with including a generous amount of the omni source.

Thanks to friends at tapersection I now have several pairs of these.

My second pair was just modified by removing mic from case, and wiring a cable to it with shrinkwrap.  Similar to what Moke did, but instead of a brass tube, I just covered everything with heatshrink LOL.
During this process I removed the mesh and the waterproof covers on the mic.  There is a thin diaphragm, some kind of spacer, and a standard (4.5mm) MKE2 capsule underneath.
I believe there is still an extra "umbrella diaphragm" inside the capsule, just like the standard MKE2.
These sound very nice.  Will be using them for (dry conditions) field recording.

So Richard, you're using one pair without the wire mesh and rubber boot around it? I'd love to hear you're thoughts on the difference in sound if you ever do a comparison.

I took the wire mesh off, removed the protective diaphragm and glued the mesh back on.It is a thin (plastic) diaphragm in front.  Just peeled it off to expose a 4.5mm MKE capsule in the center of a plastic/rubber housing.
Yeah, I will do a comparison eventually.Ideally a comparison would have left channel original, right channel with exposed capsule, mics close together, both recording the same material.

Tried the MKE2 (naked capsules) today for rock and roll recording.
A rock band with small vocal PA + guitar and bass amps + drums.  Mics up close, 3' from stage, lying on a table.Zoom F1, plug in power, MID level setting.Just reached clipping 0dB level.  Richard
