It works Sergei! Did the sim using values of 30mH, 1.5k and 8200pf, and this is the resulting FR graph: https://drive.google.com/file/d/1MgKIrcMN2YUth1J5fzaO9vWTKHXtO0eE/view?usp=sharing

Anyway, since the public is interested in taming the 10Khz peak - here is a three component solution. Three elements should be connected in series in whatever order: 30mH choke, 8200pF capacitor and,

Thanks for all the info Pat. I think I might give it a go with building an improv mount, being kind of a sucker for the popsicle type - if you pardon the pun ?

"one might want to start dumping HF at 5KHz and get the worst of the hump and NOT chop off above 10-12K where the hump is rolling off anyway?? A poor Man's wide-notch filter, or effect." - why not

Welcome to the EM172 enthusiast group. I have some experience with EM172. Worse with the theory ;-). My suggestions: 1. SimpleP48 - very simple and very good indeed - should work with cables up to

Well, or get one of the ZRAMO mikes on Amazon that HAS a 25mm.? OK, so, this mike, I use the 1" I.D. slit-sided pipe foam and make a disc for the 25mm to glue into.? It comes stock with a 16mm in a

Reckon I¡¯d fit a 25mm element in one of these?

HL, whenever this comes up I consider the two reasons I would use? it: - the economical 34mm capsules [taming that hump you can have a not-too-bad mike for very little $] and - The stock 16mm

Hi there I'm pleased to be a part of this group. I have built my first microphones following Tom Benedict's excellent instructions

I remember that in the original Jule's Pimped Alice Schematics, 470p caps where to ground. I have used them in both ways, with no aparent differences. Anyway, I just did a quick comparsion graph

Hi -- does anyone have an EM184 (or two or three) they'd like to sell? I need to replace one that apparently went bad in a mic I made. I'd use something else but it's a four-capsule combo mic and I

"it is also present if no 18nf attenuator cap is in place" - OK. I.e. my main concern is that the proposed HF attenuator does not increase the bump amplitude. Regarding the 470pF capacitors - you

Hi Sergei, I sent a reply a few minutes ago, but it didn't showed up on the group. I wrote something like this: Yes, the bump shows on the LTSpice sim even if no 18nf attenuator cap is

Homero, I'm interested whether the added HF attenuator, which is 18nF capacitor connected between source and drain, causes any magnitude response bump. For that you need to first take measurements of

Just tried it, and it is also present if no 18nf attenuator cap is in place. Have a look: https://drive.google.com/file/d/19ABlfVWZ799kV-IA5SRvucpd18z_w5Sa/view?usp=sharing

Is the bump the result of using the HF attenuator, or it is also present without the HF attenuator ? --Sergei.
