Reducing the sensitivity of electret capsules with built-in fet
Hello,
is there any way to reduce the sensitivity of an electret microphone capsule with a built-in fet transistor? Something like a -10dB or -20dB pad?
Thank you.

"I'm thinking the longer one may give a bit more holding area if using a mic holder and windscreen, yes?"
I clip the XLR plug in mic holder when using windscreen.
But yes - extra 10 mm might be

Re: Handy metal body for electret capsules.
How do these mics compare to the built in DR-70d mics? Asking because I have the same unit. I think the built in ones sound pretty decent.
I did a modification on my unit as recommended by Jim

Unfortunately not the short one.
But here's the longer one.
Practically identical minus the PCB.
The short plastic tube (collar) pushes (holds) the XLR plug in position.

Re: Handy metal body for electret capsules.
It's easier to desolder original wires than the PCB ?
So I used the shorter version first.
Photo shows difference in lenghts.
BTW they're 22 mm in diameter.

Handy metal body for electret capsules.
I happened upon Boya 35C-XLR, 3,5 mm jack to XLR adapters and they are inexpensive (around 10 USD), full metal (aluminium) and well made.
There are two versions: one, shorter - 58 mm, just plain 3,5

Yes the PZM setup sounded like it increased the peak above 5K more than the rest of the frequency range.

Re: Stefano's measurements of the PUI5024
Agreed. Thanks very much Stefano for your efforts, and for sharing them.
The extended bass response was eye-opening. Without doing the math, I had hoped that selecting 2.2uF instead of 5 uF when I

Re: AOM5024 "Modded 3-Wire" Approach
