Today I stumbled upon an interesting project that might also be of interest to some mic builders. It appears that Stuart recently detected a rare sine wave in the magnetosphere, during one of the

I did a tear-down of a $14 USB mic here: https://audioimprov.com/AudioImprov/Mics/Entries/2024/6/30_USB_Mic_Teardown.html This particular example was much better than I expected, especially for the

Welcome to mixed signal design. There are a lot of challenges to this. The opa1642 needs Well filtered supplies but also the high impedance side of things need to be well shielded from the digital

Hi, This is a pretty late reply but I'll share what little knowledge I have in the field of speech enhancement. I apologize in advance if the information posted here is technically wrong or

Hello, To provided an update to this DIY project, I've made an initial implementation with mixed results: The amplification scheme does work and the quality of the microphone output was

Thanks a lot! Found it on Mouser.ca since I'm in Canada, same part number!

When I connected the NT1-a to the audio interface today and turned on phantom power, it worked right away. I feel like the microphone is gradually working and sounding better since we started

I purchased mine from RS Stock No.: 187-8627 <https://au.rs-online.com/web/p/polymer-capacitors/1878627> Mfr. Part No. T520B107M010ATE070 [email protected]> wrote: -- David Walton

Good morning David, I just discovered the same issue! I use my Sanken COS-11D and Countryman EMW using the Rode Wireless GO II on my Zoom F4 with great results. However, I tried pluging directly

Hi Jerry. Here are the results from today but I'm not sure if I was fast enough to measure all points before the mic started working. At some points I had to wait until the value on the scale settled.

Yes, that should work well - especially with the large number of gel packs toss in the bag after the washing machine. Yes, fine business. :-) The capsule should be fine - they work well - BUT

Many thanks Jerry! It was a bit hard to read, that's why I wanna make sure I measured the right points. I will measure the non-functioning state tomorrow at about the same time and send you the

This seems correct. What about when the mic doen't work?

Here you will find the results (mic working state): A=5.04 B=7.64 C=1.16 D=0.55 E=7.50 F=15.36

Can you read the voltages on the various points?

I uploaded a NT1-a PCB photo in much better quality ( /g/MicBuilders/files/Heinz_Files/NT1-a_Maesurement_Result_001.JPG ) to the Heinz_Files folder.

Hi Jerry. I measured various voltages on the circuit board in the working state (with reference to ground) but I'm sure I missed some. Can you circle the points on the circuit board that I missed? *I

Having a spare capsule around is handy. A K47 copy isn’t acoustically like the original capsule, but it will work with the R?de flat-response circuit and is a popular upgrade. Edge terminated
