In some cases, hum is due to cheap or bad cables. A longer cable often pic up more hum then the capsule. Am So., 7. Juli 2024 um 10:53 Uhr schrieb Jerry Lee Marcel via

[Quote]What I want to focus on is whether it would be advantageous to use an Audio isolation transformer. I also use the SimpleP48 circuit (I used it for two theater events at our school). But

Hello Adam, Maybe the hum is related to your recorder/audio interface? I built several mics with AOM5024 in different casings and experienced no issues. Even when I was, recently, recording trams

You can try reducing the value of the 2.2uF capacitor, but the cut-off frequency depends on the actual input impedance of the preamp it is connected to. You need to experiment. Trial and error.

Hello Everyone, My question is how can add 80Hz LF to SimpleP48 circuit? Mainly, I'm using PUIAUDIO AOM-5024P-HD-MB-R and Panasonic WM-61A. Many thanks.

Hi Mauricio, Yes, WM-61A is excellent and tiny, but I prefer AOM-5024P-HD-MB-R :)

Hi Kenn, Yes, I absolutely agree with you, I have about 30 AOM-5024P-HD-MB-R and 200 Panasonic WM-61A (bought about 10 years ago, only used about 12). What I want to focus on is whether it would be

Hello everyone, The Panasonic WM-61A microphone is excellent. I have used it many times in different situations and applications. Be careful when buying it, as there are several imitations. I have

The Panasonic WM-61A was good in its time... but there are now much better omni electret mic capsules, that will give you better sound with less noise. Consider the PUI AOM5024L, or the Primo EM272

Hello everyone, Are you aware of this website? I have been following it for a while and I would like to make this microphone WM-61A Probe-T ( https://ameblo.jp/shin-aiai/entry-12853318085.html ). What

The Audio-Technica patent ( https://patents.google.com/patent/US10382852B2/en ) is very much in force (anticipated expiration 2038). However (with the disclaimer that this is not legal advice and I'm

Sergio, Thanks for the report!? Very interesting, and I'm assuming that the Audio-Technica patent is long expired at this point. The outside transistor on my sample also had "3FN" on it. -Scott --

So here is the full non-CORE DPA 406x teardown. Scott Helmke already kindly posted a couple of photos of the capsule here ( /g/MicBuilders/album?id=295709 ) , I am reproducing them

It's really nice that in Jan's charge amplifier topology the BJT is actually doing useful work at AC. For the Schoeps phase splitter we really want to keep it quiet at AC (hence turning it into a

OK, so I decided to publish my impedance converter circuit as well. As depicted here, it operates from 16V. It looks quite similar to Sergio's circuit, doesn't it? However, in this circuit, there's

The bottom looks like a common pad that three wires use. Could be for ground. Best Regards, Jules Ryckebusch

An electronic Albuterol inhaler had me puzzled.? Somehow it senses air motion, drawn by the user's lungs, to vaporize and deliver medication;? there is no power switch but an LED indicates air

You just hit the nail on the head with availability of good FETs. TI has a really nice one that is extremely low noise but is SMD is a weird package

It looks interesting. I have the following questions: * One of the biggest hurdles to making FET impedance converters is the scarcity of suitably good FET transistors. Does this circuit/technique
