I just confirmed (Keithley 610C electrometer) that the resistors in the Nakamichi CM-300 mikes are 1G Ohm even though the color code is orange- black-violet or...

oh please keep this on the list, it is fascinating and i have been very tempted, when there is time, to try out your charge amp circuit with some transound...
i think circuit diagrams should not be removed. they are a resource. i do think we should pare sme of the stuff we have on the group site - like old...
Hello Scott............Pls carry on. Though I have joined this group recently, as far as I have understood this forum or any other for that matter, no mail...

I've been doing a lot of binaural recording lately with Sennheiser MKE2. I really like the sound, but they are not that "trasparent". I'm wondering if it is...
I have just finished my first mic. Its a XY stereo mic with a basic preamp inside the body for field recording, powered from a 9v battery. I made the pre amp...
Hello everyone. I made a body from aluminium tubing with 60mm diameter. The body is great.....well.....not very perfet cuttings but ist ok. The only problem i...
You might look into the DPA lav mics. In general lavalier mics such as the MKE-2 and the Countryman B3 are optimized for theatrical productions - taped to a...
Mr. Wurcer, please do keep posting stuff like this. We need State of the Art stuff on the forum. The Mk5 Soundfield Mike uses 50kM, ie 50G. Ken Farrar, the...

Hi again, Maurizio, of course, I forgot R7 last time, but luckily Charles reminded you of it. 1) Is C4 there to filter unwanted incoming high frequencies? I'd...
Hi again Nisios, 60mm diameter is quite large - do you have pictures of it :) Is it the mic mentioned in your other post (stereo and with included preamp?) I'm...

For my own mic bodies, I use Brass or Aluminum hand railing, for which matching end caps are also available. This makes mounting the XLR connector in the end...

Hi Rick, Before I purchase your ribbon mic plans, I was wondering how difficult it is to build in terms of schematic reading and soldering? Thanks...Joey D! ...
The mic is the same i mentioned in the other post. Ill post some pictures.....just have to go get my camera that i lended to a friend. I already used a hole...

Welcome Nisios, I think the 1uF simply was a mistake. Sometimes you find a (much smaller, and depending on the resistance) capacitor at this place fo filter...
