Do you have a resistor between drain and source? Primo recommend 5.6KOhm but you can adjust that value to change the sensitivity. Cheers Jack

I apologize for not being more specific about the capsule type and microphone circuit. I need to reduce the sensitivity of the Primo EM200 capsule in the KM84 circuit. I have a working microphone, but

You can do the "Jerry Lee Marcel" mod. Check Stefano's or Ricardo's files. It will reduce sensitivity by about 10dB and about 15dB more max SPL, with a 2.2k resistor. But you need to make the 3-wire

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. M.

Migs - sure thing, here you are: http://taperssection.com/index.php?topic=172795.0 This is FAQ, I guess the easiest way to navigate this huge thread on DR-70D in general and there are links to

Hi folks and "Merry New Year! " (as one E.Murphy would say) *@pmfalcman* when you say "I found a long thread on this mod and I got less excited ;)?No one made proper side by side comparison

"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

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

I'm thinking the longer one may give a bit more holding area if using a mic holder and windscreen, yes?

Great photos, thanks! They really explain how the units goes together.

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.

That's how they look plugged into Tascam DR-70D

did you by chance photograph the adaptor disassembled?

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.

looks like a great idea....just to clarify, you used the shorter or longer version?

Those look great -- thanks for sharing the details!

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

lol SASS should be fine Best Regards, Jules Ryckebusch

Yes the PZM setup sounded like it increased the peak above 5K more than the rest of the frequency range. Best Regards, Jules Ryckebusch

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
