Can these be made into stereo and used with USB-C on a android smartphone? I would like to make a mic that looks like the Sony ECMLV1 and Olympus ME-51S but has the EM172 and USB-C connection where you can just plug it onto your phone and then record video with a nice enhanced mic for lots of ambient pickup, is this possible?
I’m sure it’s possible since USB-C mics exist, but I think it would come down to the voltage supplied to the capsules. The EM172 and 272 capsules work best between 5-7 volts. If you build one I would love to hear your results
@@acoustic_nature I built one but the problem was it picked up too much noise. If you were out in the middle of nowhere and just wanted to pick up crickets or something like that it would be perfect. They sell another capsule that picks up a little less noise like from the lower and higher ends and it works a lot better for ambient like if you're going into urban environment or going into a store and filming something like that. But I would think these capsules are definitely just for like I say field recording
@JohnDaniels Glad to hear the idea worked. Yeah, high sensitivity omnis like the EM272 pick up everything. If you’re after more isolation on your subject, cardioid capsules could be the way to go. Check out the EM282 or EM297 from Primo Microphones
Great tutorial! Just one question, if both capsules have to be soldered independently with a piece of hot and cold lead each, how do you combine both of those leads to the TRS connection at the end? It feels like we skipped a step in the middle a bit.
The ground (cold) for both capsules are combined and soldered to the sleeve. The hot leads are independently soldered to the tip and ring of the TRS connector.
For an XLR version, check out the resources below. The circuit is called the “simple p48”. Here’s a couple links to some great resources on the subject, the first being extremely detailed PDF document and the second a tutorial: content.instructables.com/ORIG/FG3/U9FC/KCBY3DGQ/FG3U9FCKCBY3DGQ.pdf tombenedict.wordpress.com/2016/03/05/diy-microphone-em172-capsule-and-xlr-plug/
Mine came unsoldered. Do both insulated wires go to the positive terminal on the mic? (one is white and one is red, then they both have uninsulated grounds).
Yes, but it depends if you are wiring for stereo/mono. If you have two mics, the red will go to one positive terminal and the white to the other (typically the red wire is for the right channel). If you only have one mic, twist the red and white wires together and solder to the positive terminal on the back of the mic. Do the same when wiring your TRS connector.
Hi Davie, the EM272 capsules are quieter than the internal LS-10 mics by a fair amount. Hopefully I'll find the time soon to make a comparison. I'll share the comparison with you when I do!
@@acoustic_nature I'm sold now, thanks. I will definitely be building a similar setup. Thank you for the invaluable information. If you have any kickback links to the parts by the time I get to this little project I will be sure to be using them. If you set any up I would prefer to buy the Em272s without wires as I plan to use less rigid cables and shock mount the capsules.
The distance depends on how long the cable is if that’s what you mean. If you’re referring to how far apart the mic capsules should be, I like to use 20cm. Our ears are spaced at about 20cm so using this distance can capture more realistic sounding stereo recordings.
Really thank you for this tutorial ! From one of your Blog article, I just bought yesterday a Clippy EM172 (minijack connection), and forgot my Zoom H4n only supply phantom power to the XLR inputs... i guess i will have to make some soldering (from mini-jack to dual XLR)... any tip for wich cable to connect on wich pins on each XLR male ? Keep the great work, i really love your blog, articles and soundscapes !
14 year old me would've loved to see this build in such helpful details. Great vid
Thanks David! I wish I had made my first at 14. I hope yours turned out alright back then!
Exactly what I was trying to wire with a few capsules from aliexpress, and I didn't find a single tutorial as straightforward as yours! Thanks!
Thank you, glad to help!
I know nothing about electronics so it was nice to see how these are put together, thanks
You’re welcome, glad to help
Excellent straightforward tutorial, has given me the confidence to try it out.
Awesome, good luck with your build. Let me know if any questions come up
@@acoustic_nature thanks , will do.
Thanks for perfect guidance video! 😃👏🙏 really appreciate it!❤
Great video
Thanks for your generosity
You're welcome!
Could you perhaps upload a sound sample please? Would love to hear how good the self-noise performance is in an ultra quiet environment.
Here’s a SoundCloud playlist with nature recordings made with this stereo mic: m.soundcloud.com/acousticnature/sets/clippy-em172-recordings

How do I connect the XLR connector? THK

@@acoustic_nature Thanks!
Your channel is ill be trying this build. Would it be possible to wire 3 capsules to 1 jack ?
Yes! My friend Douglas has experimented with as many as 4 capsules per channel: on.soundcloud.com/2BgLiLf5ZXEDMisv7
Hi, I see you are using the Olympus Ls-10. How do these mics compare to inbuilt Ls-10 mics? Possibly a comparison video?

Can it be used for recording much love in 🇨🇲
Yes, this microphone is great for recording almost anything. It has an ultra low noise floor so no hissing!
@@acoustic_nature ok so hw far can be like hw meany MM

Is it can be for asmr? This js really cool tutorial !
Thanks! Yes it would be great for a budget ASMR mic build

Thanks so much for your comment Nicolas! The Zoom H4n also provides plug-in-power for mini jacks so you should be good. No need to wire any XLR cables
Just be sure to turn on plug-in-power in the settings of your H4n
@@acoustic_nature Thanks for the tip, will try that 🙂
You’re welcome 🙂
