For your project I'm not sure going the Zoom way is the easiest. You find a lot of easier builts in this group, and swapping can be done based on standard XLR connectors (XLR3 or 5). This makes up for

Newbie here, so sorry if I missed previous discussion on this topic. (Yes, it tried searching but didn’t find anything…) I am working on a project to build a hand-held stereo sample

They mostly are. Check out several of the commercial ones for ideas. Interestingly, 8 capsules is not quite 2nd order, in theory you need 9. Whatever geometry you end up with. The Sparta Arrary2SH

The Schoeps cmc-6xt can be configured to record subsonic https://schoeps.de/en/products/colette/microphone-amplifiers/cmc-6xt.html just have to be careful with them in the rain

Thank you, what is the geometric position of the 8 capsules ? are they still based on a tetrahedron ?

Hi Casey, Yes that's exactly what I did. I'm sure someone must have done it but couldn't find a reference anywhere. It's a very pleasing use of phantom power symmetry. I will match front facing

I assume this is what you did, but in case it's useful here's the fig8 I've been using <http://caseyconnor.org/pub/audio/electret8/SP48_fig8.png>. As others have said on this board, it's important

I should add, as my last post was a bit confusing, that the capsules are wired with capsule 1+? to pin 2 and capsule 2+? to pin 3,? which gives the right bias. Richard

Hi, I've been a long -time lurker. I thought I would post up something I'm working on. I've been interested in getting a small, inexpensive Blumlein pair together for recording piano and thought I

You could easily extend this to 8 capsules You would need to redo the design for the capsule mounts I would probably go to 16mm capsules if I were to do that to keep them closer. Best

Jules devised the AmbiAlice for his Instructable so he can advise, but I suppose since his design uses the "Simple P48" circuit, I suppose you could use 8 conductor tube microphone cable, maybe? You

Jules' Ambi-Alice.

Thanks, Jules! Before ordering, I searched the Micbuilder Group on this topic and found a lot of useful information on capsule soldering. Many thanks!

What Ambisonic mike are you using?

That is good solder. I use the same except water based flux. -- Best Regards, Jules Ryckebusch 214 399 0931 Linkedin <https://www.linkedin.com/in/jules-ryckebusch/>

Many thanks for your advice! For soldering I used a No-Clean Flux Core Solder, 63/37 with a melting point/range of 184 C (363 F). Do you think this is OK or would it be better to use a different

There is also low temperature solder, that avoids themal stress. Am Sa., 2. M?rz 2024 um 05:54 Uhr schrieb Heinz <heinz.hartfiel@...>:

Many thanks for your advice! I think my soldering technique lacks better preparation and more professional execution. Next time I'll be more careful. To avoid thermal damage of the capsule a friend of

yeah... with most electret capsules, you really have to avoid any kind of physical stress on those tiny solder-pads. It doesn't take much force at all to tear the metal pads off. For that thickness of

Directional mikes, ie Fig-8s or Cardioids are inherently limited in LF response .. as are most (all?) LDCs.? I have a list of the best Fig-8s & Cardioids for LF response in my Files\Readme. The most
