Make sure you are looking at the correct graph -- AFAIK the frequency responses are about equivalent in terms of flatness. Maybe you are confusing the low frequency section with the whole spectrum?

Hi all - I am looking at the message board file by Stefano Simonelli ( /g/MicBuilders/files/ss%20files/SimpleP48%20PUI%205024L%20HD%20FULL.pdf) and it seems that the "Modded 3-Wire"

Jules Ryckebusch: It would seem that pin3 to the capsule "+" is the right way to do it. Also the U87 you have is wired the same way according the test you have already done..... Still there are a

Most of the data sheets for electret capsule show them with the FET's source grounded and the output taken from the drain, which suggests that the electret diaphragm produces a negative pulse when

The following photos have been updated in the Scott Helmke ( /g/MicBuilders/album?id=186281 ) photo album of the [email protected] group. * FET topology.jpg (

Since I don't think I've seen it come up yet, here's the basic FET diagram relating to polarity. With a simple two-wire connection to an electret you're getting the inverted output (also that bottom

I recorded a couple handclaps and snap sounds with the SimpleP48 wired with pin3 to the capsule "+" and this is the resulting waveform. [image: Screenshot 2023-12-26 at 7.56.53?AM.png] [image:

thanks again all for the links and suggestions @adrian- yes I buy from Nick at micbooster all the time, v helpful and excellent service

Sorry to contradict you on some points. You cannot compare directly a standard externally polarized capsule with an electret capsule. First because the former is parallel-fed, while the latter is

For as far as i know, and you said it already, the electrons are trapped in the electret, so it is impossible for them to move. So you cannot measure anything. Not by a multimeter or something like

Conrad is very expensive. I buy most of my stuff at Reichelt Elektronik. They sometimes have PUI-Audio capsules in stock. Am So., 24. Dez. 2023 um 17:39 Uhr schrieb ilya dontsov

I hadn't realised that... I had always assumed that if you reverse the polarity of the DC to a capsule element, you would reverse the polarity of the signal from it? I had thought that was how you use

Arjay, if you reverse the capsule connections in a normal “true” condenser mic, nothing happens there, either. Electrets are weird. It took some experimentation for me to figure out how an

wow, thanks so much for the lightning quick responses. Oodles of choice there, thanks and happy xmas to all D

The latest ZRAMO TH900 donor mics I bought from Amazon (BM-700 bodies and circuit boards with 1” CM-012 electret capsules) worked out of the box for once. Still “outa phase” with a Neumann, but
