Sennheiser MKE2 Waterproof GoPro mic - hacks and modifications
« on: January 16, 2019, 10:20:39 PM »
Thought I would start a thread in the appropriate forum to avoid clogging up the Retail board.

Please discuss your mods to the Senn GoPro mic and post pics so everyone can follow along.

Original thread for reference: http://taperssection.com/index.php?topic=188670.0

From the other thread -

email from Sennheiser -
"The MKE 2 capsules are the same (as the regular mics), but the form factors are different.  The units for the GoPro HERO 4 are integrated into a housing to make them waterproof when used with that camera, and have different connector types.  The Regular MKE 2 are not waterproof, and have either 3.5mm or Lemo connectors"

Specs from the Sennheiser site for the standard MKE 2 -

Frequency response (Microphone) - 20 - 20000 Hz +- 3 dB
Connection cable - LEMO f. SK50/250
Cable length - 1,6 m
Weight - 77 g
Sensitivity in free field, no load (1kHz) - 5 mV/Pa +- 3 dB
Nominal impedance - 1000 Ω
Min. terminating impedance - 4700 Ω
Equivalent noise level - 26 dB
Equivalent noise level weighted as per CCIR 468-3 - 39 dB
Maximum sound pressure level (passive) - 142 dB
Current consumption ca. - 250 µA
Operating voltage (stand alone) - 7.5 V

verified working mini plug wiring  -
Left mic>red wire to tip
Right mic>red wire to ring
The 2 blues and 2 shields to sleeve.

Thanks for starting this. I was thinking about something like this earlier this evening.

I'm not entirely sure about the waterproof factoid for our use, but, could be wrong.
The thing is designed to seal to the back of a GoPro, and has that rectangular O-Ring around the perimeter to create that seal. That seals the unit to the GoPro. The only other exposed point is the rubber mast that exits the box, and that is frequency welded (it appears) to the box, to create a seal.
In our application, we no longer have that sealed environment, unless someone creates a closure "door" to fit the GoPro mounting box. I'm thinking this to be a clearable hurdle with 3-D printing tech.
I could be totally wrong, but, caution should be used until I'm proven wrong.

Moke's brass tubing body looks promising...The windscreen is a big draw for me on this item...I'd love to incorporate that into a modified housing...could you cut threads the next larger size tubing to mount the windscreen?

In. Hopefully I will have some time this weekend to tinker - I have a female 3.5mm jack on the way. Has anyone else gotten one of these wired up to a miniplug?

Greets,
The 1/2" o.d. brass tubing fits flush to the diameter of the capsules widest point.  I tried the windscreen on, and, it is a really nice friction fit without the need for screw threads.

I'm going to grab the images from that other thread, and import them here.

the crappy image 6044 is 1/2"o.d. tubing fit.  This will need to be epoxied into place. It is a nice fit inside the tubing, but, not tight enough to be a friction fit. The windscreen fits nicely over this mounting.

.............................................................................

regarding the other images and tubing (also picked from other thread):
http://taperssection.com/index.php?topic=188670.msg2288043#msg2288043

It appears to be .25" o.d. on the smaller tube.
The larger is .28" o.d.

8131 (smaller) and 8132 (larger) is the K&S Precision Metals product numbers, I think.
http://ksmetals.com/26.html

...............................................................................

in regard to the larger 1/2" tubing:
http://taperssection.com/index.php?topic=188670.msg2288067#msg2288067

It is a piece of 1/2" o.d. part# 8139
It fits very nicely, and touches the "flanges" just below the round collar, for a nice tight flush fit. It would need to be an adhesive fitting, as it is not snug enough by itself

I purchased a Neutrik 3.5mm female stereo jack (https://www.bhphotovideo.com/c/product/888470-REG/Neutrik_nys240bg_3_5mm_Stereo_Jack.html) to wire up but I believe something like the option below may be better for  >:D.

I'm thinking I could just strip the ends of the 3.5mm plugs and wire them to the mics with a little heat shrink to keep things tidy.

What do you guys think?

Why not just a stereo 3.5 mm (1/8) male plug? I ordered an "L" shaped one and hope to tinker this weekend. I snagged 2 demo MKE2 models at a whopping $2.00 less per mic, but as I figured they look brand new.

I'm mounting the mics and the jack in the liner of a mesh trucker hat and I'd rather have a male jack hanging down than a larger female jack. It's a little hard to explain but I'll post pictures when I'm done.

Can these microphones be attached to Apple iPod/iphone type headphone wire?  I know absolutely nothing about wires/cables/microphones.  Would it be better to solder to a stereo mini plug then attach that plug to another cable of your preferred length?  Approximately how much wire do you have to work with once it's free from the usb board?

I only have a 6" scale at hand. It is slightly longer than that by an inch'ish or so. 7" is a safe length guess.

You CAN use that wire but I would just grab some nice Mogami microphone cable - you want a nice shielded wire for these and that headphone wire will have a lot of extraneous material that you don't need.. If you wanted a long cable, I would solder the mic to a longer cable and put heat strink tubing over it to protect the joint. I'm putting my pair to a Y cable so I don't have to worry about extending them.

Has anyone cut the rubber tubing and mesh screen off this yet? The waterproofing jacket I guess you could call it. Still on the road and haven't had mine in hand yet.

I want these to be as small as possible but thinking of a way to maybe adapt them somehow to fit back into a portion of the housing to be able to mount them in the open using the windscreen.

Here are some photos of the case and microphone:







That's as far as I've gotten with mine.

^ if you score the rubber where it meets the plastic housing, you can simply pull the microphone out, rubber and all. It takes a bit of tugging but it came out with no problem.

But if you want to keep the treaded part intact to use the windscreens you might leave them attached and Dremel the threaded part away from the case.  I did as you suggested above and it wasn't much trouble at all.

Look at what Naiant uses on some of his microphone housings...that looks like a RCA male connector with the mic element sticking out where the cable would come out....



Thinking of disassembly of the below female 1/8 TRS jack inserted at the back of Brass Tubing...that would prevent the wire being torn out of the Mic capsule in the original plastic housing...

MøKE2 1.2 completed

at least at the mic capsule/body end,... I still need to do the stereo connector end.

img6092:
The journey begins at the 1/8" 3.5mm trs stereo connector.  I always end up needing the extra room in the screw on cap. So, first matter, enlarge that hole, and clean up the drill hole.

img6096: Commitment time. This was kind of hard to do.

img6099: My eyes said screw you Moke!

img6100 & 6101: Hiding my soldering skills

img 6102:
Inner brass tubing mounting the rubber shock mount mast.  This layer fits inside of the outer tubing, and allows the shock mounting to move freely.  I epoxy bedded the inside of this inner tubing piece, which also contained the soldering joint. I covered the soldering jpoint in two layers of heat shrink, with cyanoacrylate gel glue applied between layers.
The rubber mast was epoxy bedded on iserion into the inner brass tube, and the backside was filled with epoxy as well, for a 100% waterproof seal (I've rigged boats and know how to seal through-hull fittings). I cut the inner tubing piece at 5/8" long, which covered the solder joint entirely.

img6103: outer tubing pieces.
I cut these at twice the length of the inner pieces at 1.25" (or as close as an angle grainder would allow).
The outer tubing was epoxy bedded with internal epoxy smeared into the lead-end of the tubings, and, onto the heatshring at the interface, to completely fill the void. Overflow oozed, and was cleaned off. An adjustment was made, prior to the epoxy setting, to ensure that the shockmounting was still viable before the epoxy set the outer tube into place.

img6104 - 05 - 06:
Finished capsule and mic body. I tried to show the epoxy bedding and seal.
I'm going to cover this in heat shrink, and, self adhesive velcro, loop-sided tape (not the hooks), for ease of strapping to stands, and spreaders, etc.

I used:
Mogami W2697 Miniature Balanced Mic Cable - lavalier mic cable
K&S Precision Metals Brass tubing, #'s 8131 inner & 8132 outer (confirmed numbers - previously speculated)
Switchcraft 1/8" 3.5mm TRS stereo male connector - straight
JB-Weld KWIK epoxy (you can fix your tractor with this shit!)

A couple of build-up observations:

The smaller inner tubing piece could be used as a solo piece of tubing.  When dry, the rubber grabbed the brass, and only allowed a small insertion into the brass tube.
When epoxy was applied, it acted like a lubricant, and, the rubber easily slipped into the brass tubing piece, all the way in. I had to adjust it back out.
So, the inner tubing piece would be adequate for lower profile build.
The inner tubing piece has an o.d. of .25", whch is an easy fit for heat shrink, as opposed to the next larger that I finished with, which was not as good a fit with the shrink tube. petty, but,...

Use of windscreens:
On my build-up, the windscreen fits over the capsule perfectly, by its own design.  I have actively shaken the mic, while upside-down, trying to dislodge the w.screen, and it stays put, perfectly.  I don't feel the threads are necessary to allow them to be used.

That is really good to know.  I want to be able to use the windscreens and assumed that I'd need to keep something for them to thread onto.

While recording, is there any audible effect of the mic moving within the windscreen?  Or is it a snug enough fit that it's not an issue?

We're supposed to get a strong Santa Ana wind event tomorrow, or, over the weekend. I'll fly them, and see what happens. I won't be anything more than a nature recording, and, noise from the road in the distance. But that will reveal a wind signature well enough.

So, I sort of prepared this, this morning, with the best of intentions.
Problem: Pre-coffee; the eep hour for Moke
Result: Misnamed main folder.
Presented as: https://archive.org/details/test2.horizontal

Testing the windscreens this morning in a stiff Santa Ana wind.
I tested the mics with the windscreens on, without any form of securing them to the capsules.

I tested them in four ways:

Test-1) Dangling, swinging freely
Dangling from a spreader bar, with the windscreens providing their own vertical loading.  The wind was strong enough to cause them to sway back and forth, and, also causing the stand to wobble.

Test-2) Horizontal
With the mics velcroed to the spreader bar in a horizontal attitude; cables parallel to the length of the spreader, capsules at end, pointed outwardly, horizontally.

Test-3) Vertical
Mics mounted with capsules vertical, perpeindicular to spreader bar.

Test-4a&4b) As same track.
I spun the mics as if they were a set of jump ropes.  Then I clacked them together a few times at the end of this track.
stupid crazy audio. point: The screens stayed in place.

all said and done,...
If for nothing better, you can hear the birds that Sarge attracts to the yard. I love them.

Boy, it's been a long while since I've modified any mics. This is very, very intriguing for me. I just bought (4) to mess around with. I just love recording with omnis. Waterproof omnis are all the better. I just skimmed both threads and have a basic understanding of whats going on. It looks like the hardest part is separating the mic from the box housing?

I'll read more in depth before they come. But, I have a quick question to make sure I'm seeing this clearly. Once you get them separated from that box all you have to do is terminate them properly and use them with a 9v battery box? There is no additional circuitry needed to make them high SPL ready for recording?

The hardest part for me was wiring them up as the cable is so delicate. To remove the mics, you just pop off the bottom plate, score the rubber sleeve where it meets the plastic housing and pull out the mic. It takes about 2 minutes.

Max SPL for the regular MKE2 is 142 db. I think these should be good to go without mods.

Agreed on the onboard wires. really tiny.  The kevlar thread is a pita too.  It took a while to finally see the "blue" wire that is suggested. It is a very light ice blue. I felt it before I really "saw" it.
Almost as hard,... that first cut across the wires to shorten them.

I finally got around to messing with one of mine.  First I pried up the inside panel, which was easy by using a screwdriver.

Second, I broke out the Dremel.  (This is where things always get ugly.)  I wanted to try keeping the threads for the windscreen, if for no other reason than to see if it would work.  I carefully cut away at the hard plastic area between the body and the threads (if you look at it closely from the side there's a gap between the last thread and the body, so I just went to town there).  I obviously didn't want to inadvertently cut the wire, so I took my time and when it looked like I was getting close I'd stop and see if I could break it free by hand.  Eventually I could, and I was able to pull it out of the body.  There is that little flared bit of soft plastic that makes a seal with the interior of the body, and I was able to just pull that through.

I haven't tried to clean this up yet.  In the attached photos you can see the mic by itself, and screwed into the windscreen.  I'm not really sure where to go from here.  Anyone have ideas for making this easy to mount?  Maybe I could attach tubing to that bit of soft plastic that extends past the threads, a la Moke?  I want to try to keep the threads, in part because they'll help make a good seal from the elements (no pun intended).

Testing the windscreens this morning in a stiff Santa Ana wind.

Any idea what speed the gusts got to?  There are some points where there's audible wind noise (though I wonder if that would even be audible over an amplified concert).

Thanks for posting the demo of these...those birds were fun to listen to.  At one point I found myself thinking, "we don't have wind chimes...where is that coming from?"  Then I realized the obvious...

Approximately how much wire do you have to work with once it's free from the usb board?

I've got just under 6 1/4 inches.

Nice work on these things everybody! I recordered a local funk jam at the crowbar in Tampa last week, clamped about 8' up PAS into my DR-05, nothing else in post except normalize. Sounds nice, a little bass heavy, but they were backed up to the wall. I did mine up with heat shrink and am pretty happy with the appearance and feel that they are fairly strain relived. here is a sample: War Pigs closer with horns, about 12 people onstage.

My pleasure. welcome.
15->25mph probably. It was a stout blow event.  Weird, we've been getting them more at night, as night winds.

Regarding your concern about the windscreens, and, the thread set.
The amount of times that I've used screeens on omnis is minimal, and, the last time I recorded a concert outdoors was a decade ago. So, the windscreens were fairly low on my list of priorities.
Now, with tht said,... none of the test had the screens becoming loose. But, I also realize that is not what makes some people feel at ease.
So, to keep the group think alive,... I gave this a go,..
I took a velcro tab, one of the newer style, thin, die-cut, smaller cable tabs, and, I secured it immediately below the mic, on the brass body region.  I wrapped it a couple of times until it was barely too large for the thread hole, and backed it off one coil, or so, until it wanted to fit, snugly. I then coiled it downward away from the mic capsule, creating a conical interface with the windscreen.  That conical interface provided a really snug seat in an interference-type fit.
In theory, you could use the hooks side out on the velcro, and, have the hooks side gripping into the internal threads.

As I have mentioned, I'm considering mounting some adhesive-back velcro onto the mic bodies, permanently, in order to aid in velcro mounting the mics to different surfaces.  WIth that sort of anchoring, I'd be very confident in calling a velcro collar a totally adequate replacement for the threads.

nothing clears up cloudy theory like pictures!

OK,... I mounted the velcro to the mic bodies, just to test this theory.
I'm totally done, and satisfied. It is a nice snug friction fit.  Its not thread tight, but its as good as any other properly fitted foam screen you've ever mounted.

More progress, and a slightly different approach...

I trimmed a bit of the lip off the flared end of the plastic, as visible in the first picture.

Then I used the K&S 8131 tubing suggested by Moke to give this a bit of a "body," as visible in the second picture.  With that flared end trimmed, the plastic fit nicely in the tube but not snug enough to keep it that way without some sort of adhesive.  My plan is to use the epoxy Moke used to hold it in place...hopefully that little nub of plastic will be enough to secure the tube.  We'll see.

Finally you can see my final plan.  I'm going to attach a gear tie to the "body" (for now I'm just using gaffer tape, and that may well be enough in the long run as well).  I'll then use the gear tie to secure the mic to wherever I want, whether it's a stand or a railing or whatever.  I'll probably run this with just gaffer tape at first to make sure I like it as a mounting option.  Note that the bulb end of the gear tie will not fit inside the 8131 tube.

Next step for me is to attach the extension cable, and then I'll hide the connection point inside the body.  I'll probably back fill that like Moke did.

Has anyone cut the rubber tubing and mesh screen off this yet? The waterproofing jacket I guess you could call it. Still on the road and haven't had mine in hand yet.

I want these to be as small as possible but thinking of a way to maybe adapt them somehow to fit back into a portion of the housing to be able to mount them in the open using the windscreen.

I'd be interested to see what it looks like under that rubber boot too.

Chuck,
You asked about powering them, in paraphrase,...
Can you plug these into a 9v battery pack, and good?

My first test was into my mod'd DPA MMA6000.  The MMA6k outputs 7vdc. THis worked, no problem.
I also have a mod'd DPA microdot batt pack that I took the microdots out of, and mod'd into two 1/8" stereo inputs (in case one breaks live) and a single 1/8" stereo output.  This device oututs 9vdc.
So, I grabbed the new pair, and, looked into that dark black hole, and, astuck it in, and, low and behold,..... wait for it,.....
perfect signal.
9vdc is fine.

Thanks Moke. I'm set with 9v battery boxes.
What about SPL handling? They don't need a 4.7k (or other value) resistor mod to handle loud sources?

For anyone trying to get the jacket off those inner red and blue wires, a trick I read somewhere else is to use heat to melt away the end of the jacket.  I tried it with a lighter and it seems to have worked...damn things are so tiny though I can't tell if there are still traces of plastic left, but it doesn't appear so.

looking good.

The epoxy backfill was an attempt to isolate the solder joint as much as possible, to keep it stable and free of motion.  I appled some cyanoacrylate "Crazy Glue" gel glue, to the inside of the heat shrink, prior to shrinking it, to attempt the same isolating.

epoxy tip:
To center the cable, use three toothpicks, triangulated around the cable. You'll only be able to fit the tips in. Make sure to pull them out before the glue goes hard.  I mix on a paper plate, and, leave the leftover behind to test for curing.

JB-Weld has great flow characteristics!  Fill your void, and then hang the mic capsule vertically over a towel bar, or whatever, and, the epoxy will flow into and fill the voids perfectly.

Building layers of epoxy is easier than trying all at once.  I did a major sub-filling, and then a finish top-off.

Denatured alcohol cleans up JB-Weld, quite well.

Thanks for the tips Moke.  I was actually thinking about PM'ing you with questions about using JB Weld because I've never used it before.  The lav cable I need for this is on the way, and I'm hoping to do more tinkering as soon as it arrives.

Another sample added with the MKE2 pair.
This is a thunderstorm that rolled through this afternoon.  We don't get them often, and, when we do, they roll through quickly.
I set up Güde in my front entrance breezeway, just far enough back to keep from getting too wet (a few drops did hit, but minimal).  I ran the mics as the HRTF example posted in the list earlier, and let it run its course. This is with the head facing the wind, and no windscreens; It was a thunderstorm blowing through, with wind.

As the cars approach, you can hear them more to the right, and then crossing to center, and then becoming naturally attenuated, as our front slope is high to the left, and low to the right, diagonally across the sound field. By the time the cars reach center from the right, they are disappearing behind/into the slope. Cars coming down the road emerge at center, and move right.

> Birds doing their thing. It was raining, and they were mostly hiding, but audible.

> Thunder! the whole point of this.
sub-point,... in the left channel, you can hear the thunder shaking the heck out of my steel garage.
The rain is also made to sound really bright by my rain gutters.

The first clap of thunder has a touch of clipping, as I was literally running to get this set up. Our thunder storms are rare and extremely brief. When I hit record, I was a touch too hot; nothing too drastic, but, overs nonetheless. Adjustment made, and clean through the rest.

I got them on Amazon, but they aren't there anymore. I found the same ones on eBay. Search: "10Pack Mini Clip-On Microphone Holders Mic Lapel Tie Clip Replacement 12mm" Those come from China.

Not sure if it's the same, but this one looks similar: https://www.aliexpress.com/item/4-x-microphone-lapel-tie-clip-for-Lapel-Lavalier-Mic-Black/32823945525.html

They look to have a smaller grip than the 12mm clips I bought. I saw several different sizes then I found mine.

Yeah. I have a box full of different sizes of them. That's the first one I tried. I want to get the size and weight down from that one. I like the idea of using an RCA socket to terminate them though, but it does add weight.

all through that bitty little hole.

So, what did it take to get that cap off?
I'm guessing the inner silver screen is integrated within that cap?

It wasn't that difficult to pry apart. I used an exacto knife to loosen it a bit before I tugged on it. It's just glued in place. The silver screen appears to be glued on too. I did notice there was a membrane over that hole in the part that has the silver screen.

I actually didn't intend to take it all apart, but I accidentally broke the red wire so far into the thing when I was playing with it that I figured I'd just sacrifice one for the team. ;)

For what it's worth, as everyone has said, those wires are very small. I have several wire strippers and none would cut the jacket off the red and light blue wires without cutting the wire too. I resorted to using my teeth and that's how I broke the red wire. :(


So, this is my finished hack. I used the strain relief from some mini xlr plugs to seal the back. I decided RCA jacks would be the best way to terminate them for me. Tomorrow I'm going to crank up the stereo and test them against my other omnis.

Wow.  Great hacking there.
Now we finally see what is inside.
These look like they would be great for outdoor festival recording.  All those times you get caught in the rain.  Worry no more, your microphones are still safe :)
Please DO NOT mail me with tech questions.  I will try to answer in the forums when I get a chance.  Thanks.

Thanks Richard.

Do you have any idea what SPL's these can handle? There are three wires, but two are tied to each other, so basically two wire mics.

That's all I'm worried about is that they'll overload.

Plug in power, mic sens LO, level #2 on Sony PCM-M10.124dBrms @ 250Hz calibrator is just under maximum level.A pure sine wave, no distortion.
These things are not going to distort is my guess.
Perfect for plug in power.

I do like the RCA notion.  I think you did well in the mini-xlr end cap, rather than trying to build them into the rca connector.

On the wire, I practiced on the cut-off cable, and found that my fingernails did a decent job of stripping. I was able to get the wire exposed. In tinning them, I noticed that the solder just sort of pushed the insulation aside as it wicked into the wire strands.
I also used a razor blade and pushed my finger lightly against it with the wire trapped in between.  It took a portion of the insulation off, as it sort of pigtailed; but also appeared to take some wire with it.

Speculation:
Maybe not totally necessary to strip the insulation?

I also found a pair of nail clippers helped in removing the kevlar thread.

I had a chance to test the Sennheiser MKE 2's against my favorite omnis, the Audix CPS-MICRO-O.

The MKE 2's where punchier and less open sounding. They had better bass response that the Audix mics and on some material sounded truer to the source. Not as hyped as the CPS-MICRO-O's.

I ran them into a Core Sound battery box, which does not supply gain.

I noticed a few interesting things while testing.

They didn't need a mic pre-amp at loud, but still home listening levels. I just ran them straight from the battery box into my Mixpre 6 XLR inputs set to line in.

The phase was reversed compared to the Audix mics and my Microtech Gefell M300's.

They were very well matched in frequency response , but ~2db off in output.

I think the Sennheiser MKE2's  are going to be an excellent addition to my microphone arsenal.

It's good to hear your impressions.  One question I have is whether you were using the Sennheisers stripped from the bodies (like in the picture you recently poster showing the cap without the grid/membrane)?

Also can you expand on what you mean by "punchier?"

Hi heathen,

I used them with the grill and membrane in place as pictured with the RCA connectors on the ends.

The Audix mics have an airy quality about them. More top end with slightly  scooped mids. The MKE 2's are fuller in the mids and sound more centered and not as airy in the top end.

To get an idea of what the Audix mics sound like:

I just spoke with Sweetwater, there are quite a few left, WS for $10 and mics+WS for $20.
I'm going to build a few pairs of these for outdoor recording/ surveillance type applications.
If anyone wants to dis-assemble them, take off the protective screen, the raw MKE2 capsules might sound a little better without the cover.  I have not experimented with this yet.  Happy to build a few sets of "waterproof"/"windproof" mics for now.
I just bought a few more. Thanks again to members of TS.com for the connection :)

I did too last week.  It's just too good of a deal to pass up.  For $20 each I can make several pairs, each purpose-built for a specific function.

Richard mentioned the waterproof membrane. Has anyone attempted to remove this yet?

I've got a couple of sets of these and I'm scared to death to deal with these tiny wires. Anyone in the mod market to do up a set for me?

Also, props to Sweetwater. Not the first dealings with them, and their customer service is top notch.

Hi lsd2525, that membrane is part of the plastic/wire mesh section that can be separated away from the element. I haven't tried to remove it.

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.

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:

Quote
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.

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?

You're totally going to recognize the melody. If you don't, well,...

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

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.

I'd try the 9200 set to "0" and go line in to your recorder.

I'm going to try my MKE 2's on Wednesday. An ambient band with no drummer.

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.

Nope, I ran it at 5 o clock as usual (as w/ AT853) and figured since the levels on the M10 we're good, it was ok. I'm under the impression that the gain on the 9100 is fixed and the potentiometer controls the signal level output - please correct me if I'm wrong.

I don't know much about the tech behind the mics. Would supplying less power via PIP vs 9v have less of a chance of overloading the mics?

I moved back a few rows during the encore and the sound was noticably better with a small amount of clipping on the peaks and crowd noise.

Would a sound sample be useful? I think the recording is a write off.

I did a very unscientific test over the weekend. I held the MKE 2 mics in my hand and hummed/talked very loudly into them. They brick walled at some point at every setting I used, including line in with a straight battery box.  As Moke mentioned, they are very sensitive. He used around 18 db less gain than he uses with his DPA4060's!

Mine doesn't (as far as I know - just the HPF switch), but you could order the 3 wire version with a switchable 4.7k mod IIRC.

I'm planning to test out three more possibilities at a "burner" show soon:

1) MKE2 > CA9100 at unity gain (around 11 o clock) > M10 line in
2) MKE2 > CA9100 w/ attenuation (switched on to the lowest setting > M10 line in
2) MKE2 > M10 mic in w/PIP

Can someone help me understand a bit of what's happening here? I'm assuming the SPL was too much for the capsule but levels at the recorder were fine. I imagine that it is possible that the M10 was attenuating the signal to keep it at -9db but I think I had it at around 5 or so.

Mine doesn't (as far as I know - just the HPF switch), but you could order the 3 wire version with a switchable 4.7k mod IIRC.

I'm planning to test out three more possibilities at a "burner" show soon:

1) MKE2 > CA9100 at unity gain (around 11 o clock) > M10 line in
2) MKE2 > CA9100 w/ attenuation (switched on to the lowest setting > M10 line in
2) MKE2 > M10 mic in w/PIP

Can someone help me understand a bit of what's happening here? I'm assuming the SPL was too much for the capsule but levels at the recorder were fine. I imagine that it is possible that the M10 was attenuating the signal to keep it at -9db but I think I had it at around 5 or so.
If you can run plug in power, low sens on M10,turn down till just below clipping level.
Let us know that level. If it is #2 or above it should not distort.  If it is below #2 you've got brickwall distortion.

Can you guys share some tips for soldering the thin wires from the mic to the wires of an extension cable?  (I'm using Mogami W2697 FWIW.)  I spent longer than I care to admit yesterday trying to solder the wires together and while it worked (eventually...) it was bulky and sloppy.  Luckily that was on a mic that I'd already intended to be just for practice.

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.

I ended up doing red to red, but didn't solder a wire between the cups on 1 and 3.  Instead, I twisted the blue and shield together partially, so they made a Y.  I tinned the twisted part to make sure they held together well.  Then I connected each free end to 1 and 3.  That accomplishes the same thing, right?

This looks to have been answered, above, but, this is what I did,..

I first tinned all leads.
Then I cleaned the iron tip, and very lightly tinned the iron. I had the iron set at an angle to create a drip at the tip. I then brought both leads up under the soldering iron tip, and into the slight drip of melted tin. They joined, and I carefully pulled them away from the heat, and, watched the tin flash hard. mission accomplished.
One of those alligator clip/magnifying glass holder dealieo things would probably be really handy; but never around when you need one.

I did a very unscientific test over the weekend. I held the MKE 2 mics in my hand and hummed/talked very loudly into them. They brick walled at some point at every setting I used, including line in with a straight battery box.  As Moke mentioned, they are very sensitive. He used around 18 db less gain than he uses with his DPA4060's!

I usually set up a known rig in front of my home speakers and play with volume and or distance until I get normal levels at my usual settings. Set up at the same spot and you can get a pretty good starting point for levels on the new rig. I thought the mke2's were sensitive but not to the point where it wasn't manageable.

Hey folks, just wanted to let you know I seem to be having some nice success with these into my DR-05. I am not having overloading issues at all. Check out some of last nights pull. A nice show from the band, lots of originals in the first set, and a heavy on the GD second. I never pictured myself an omni guy, but it's really nice to be able to leave my 100 dollar rig just about anywhere and let it do it's thing.

Yes, nothing else, my mic power is on, and my gain setting is at -48. I may try to see if it ill run ok at a loud show at -24. I'll let you know if it can handle that.

It's good to see that these can handle higher SPLs.  I'm really impressed with how they sound from only PiP.  Do you know how much the DR05 supplies?

I believe it is 2.9 volts. I had noted earlier in the first thread that it supplies just under 3V. Having trouble finding the spec again. Also, where they were positioned, I would say it was in the range of 100db, ad it was showing about 90 at the board which was not too far away. It was nice to see a show that sounded great and din't make the ears bleed.

Maybe these won't end up being suited for super loud indoor shows.  That wouldn't bother me too much because I primarily intend to use mine outdoors, and I generally find that all things being equal the outdoor shows don't seem as loud as indoor shows.

I just did a very unscientific test with my stereo and the configurations I proposed in the previous post. It looks like PIP is the way to go - I got plenty of gain and headroom with no signs of clipping with my stereo at moderate to high volume.

So am I correct in my thinking here: The mics cannot handle the 9v of power my 9100 puts out; the post preamp signal was not the issue as it was clipping at the mic end?

Here's the waveform db from the recording attempt the other night and it was what I suspected - straight brickwall. You can see when the band started at 41:10.

That's what I was getting with a 9v battery box (no gain) going line in to my MixPre-6 1/8" jack. But, I'd think less voltage would make it worse...

Hmm.  Wonder if 9v is too high.Some digital circuits don't want more than 5v.
Anyway, Plug in power seems to work very well.No need to a battery box, just more connectors to worry about.
By the way, the most reliable solution would be obtained with Zoom F1 recorder and screw locking 1/8" TRS connectors.

I'm going to try to get a pair of mine all wired up soon, and once I do I'll go to some show I don't care about (or even a bar band...as long as it's loud) and try as many configurations as I can.  Pre, BB, no BB, etc.

If these mics end up working for loud shows, and do even better without a BB/pre, then these may be my new go-to mics for deep stealth situations.

I forgot to mention, I ran these without the windscreens on in an audio technica type mount and there was def some wind going on that night too, nothing crazy, but I don't hear it, I am wondering if the waterproof membrane might have had an impact on that.

More likely because they are Omnidirectional.
From DPA: Omnidirectional (pressure) microphones are, in general, less sensitive to wind compared to directional (pressure gradient) microphones. The difference is based on design — the pressure mic’s membrane is less compliant than that of the pressure gradient’s. The higher stiffness of the pressure mic’s membrane provides approximately 10 dB lower sensitivity to wind noise compared to the pressure gradient mic.

Right. Which is why omni's are a great choice for outdoor recording. I try to always run a pair of omnis along with whatever other pair I run outdoors. They'll produce a listenable recording under conditions which make cardioids or hyper-cardioids unlistenable.

Yes, to all of that, and adding, after extensive discussions with Bruce Myers, ex.CEO of DPA N.A.,... the venting of directional mics is to the backside of the capsule.  This creates a high pressure/low pressure offset happening on either side of the mic capsule, and causes havoc to the membrane of the directional patterns.
Me: adores omnidirectional, and sub-card.

I got my first pair completed.  I wanted to see how difficult it would be to remove the flexible "stalk" from the screw part (it's not difficult at all...as someone else pointed out you can score it and then just pull them apart), so this initial pair ended up being like Moke's with no threading.  They seem fine from initial testing at home, but my next order of business will be to get them to a properly loud environment and do some testing.  I'll report back.

I ditched the threading too. You'll notice you can still use that wind screen on what's left too. It's not super tight, but it still works.

Yeah.  I am going to look into adding something to the "body" of the mic to help stabilize and seal up the opening of the windscreen.  Maybe some kind of rubber grommet or something.

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.

Is there any chance it was an issue with your recorder?

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.
