If not frequent, that is explainable. All semiconductors are sensible to light, to variable degrees. It seems the FET in your capsule is not lightproof.

Hey, i've researched a lot about this, but i cant seem to find any explanation to what i'm dealing with... I'm using the simple P48 circuit and the PIU 5024 electret mic capsules, and i'm super

I continue to 'play around'? - DIY wise - with my attempts to record bat ultrasound. As Wim mentions above, I can live with the '¡À10dB FR spec for the ultrasonic range' of the Knowles? SPU0410LRSH

Apologies for the delay, life got 'interesting' lately.... I've attached an STL of one of the bodies I designed for an EM272. It works, however you need a small sleeve inside it to prevent the 3

Both methods require a 3 terminal capsule like PUI 5035

One option is Jerry's 'Marcel mod' in Fig4 and p10 of SimpleP48.pdf. Another is RENE¡¯S CHARGE AMP (SimpleP48RCA) on p12.? This will be slightly quieter than the 'Marcel mod'. Both will give lower

Of course, I bought several PUI capsules from Mouser. I bought them from Portugal and they were super quick to deliver. I didn't pay shipping because the purchase was over €50.

Gustavo, you sparked my interest: may I ask where you bought the 5035? Thank you.

Fantastic! I will test with various values ??for Rs. If successful I will present the results here. Your contribution was very important to me.

I can't answer that with absolute certainty, but the principle used (degenerating the FET's transconductance by adding a resistor in series with its source) works with any FET. Of course some

"is it possible to change the SimpleP48 circuit so that the PUI AOM-5024 supports more than 110 dB SPL?" Sadly no. I have tested this capsule, which I love BTW. It has a very high sensitivity. And at

Thank you very much for your help, I think I will be able to test this capsule. Since I don't know much about electronics, I would like to ask an innocent question: is it possible to change the

Yes it is different. The "Recommended drive circuit" is suitable for connection to an unbalanced input with power. Simple P48 is recommended for balanced phantom powered inputs.

Thanks a lot Jerry. I hadn't looked at Stefano's "3 versions of the simplep48" doc yet. Comparing the circuit recommended by PUI and the circuit in Stefano's document it seems to me that the resistor

Look into Ricardo's folder and SimpleP48. doc. At page Dec 2015, there is a mention of a very simple mod I suggested that allows to increase significantly the max spl. This mod works only with 3-wire

I am a sound engineer and I work mainly with orchestral recordings. My setup included Decca-Tree with Gefell M221 plus Schoeps and Neumann spots. The challenge now is to build a sound reinforcement

Hello everybody. I'm going to try for the first time to build a microphone with a PUIaudio AOM-5035 capsule + SimpleP48. The choice of this capsule is due to the fact that I need 135dB SPL of maximum
