Roger, When I took my mics to the studio, the piano was set up for studio sessions over several days. I just used the existing set up which was an x/y ...
Hi Richard! ... Great information! I will probably make an experiment or two with the basic dimensions of this design (not with the exact design, because I ...
Hi Folks, I have Build a Few Mics useing a few Different Designs I found on the Net but I have been haveing some Small Problems with the sound of some of these...
Hi Chris, You could take a look at this schematic http://www.scotthelmke.com/alice-schematic.jpg . Seems to be an elegant way. Capsule with a SNR of 58 dB are...
Hi, ThanX for the Schematic But Your Take on SNR isn"t quite Right... The Higher the SNR the Better so a SNR of 25db is REALLY Bad .... The Panasonic WM60AY...
Bear in mind that "Signal to noise ratio" is not the same thing as "Noise level", which is what the Alice is listed as. The Alice is a *lot* quieter than a...
Hi, As Scott already noticed, signal to noise ratio (SNR) is not the same thing as noise level. Microphones have a SNR meassured at 94 dB. If you have a SNR of...
I have some Primo Elements also but I can not find any Info on these Particular elements...They are the HX034P elements that I get for less than $1 each, I...
www.transsound.net Mark Strong rocks! ... Particular elements...They are the HX034P elements that I get for less than $1 each, I also have some other elements...
... I would not recommend this backplate design with the large number of fine holes. I only know 2 people who have built this mike and both broke LOTS of...
Hi have Bought elements from there before and the Highest SNR I can Find on Any of the Elements is 62db and that is a Panasonic element and they have No...
Check out the TSB-160 and TSB-165 capsules - they don't have a built-in FET circuit, which eliminates the usual main source of noise in such capsules. The...
if i remember right, the original neuman patent had to do with narrow groves (on the active side) interconnecting the holes - a way of equalising both the...
Transsound does a wide selection of capsules, including cardioid with snr > 62db. This is the most popular one and the one used in the Alice mic that Scott...
That is the Calrec arrangement. But the grooves were very deep. The groove cavity was part of the phase shifter on the back in conjunction with the through...

I'm getting some strange bump, pop type sounds from one of my mics - which were built like the "alice" mic. It's an infrequent, highly intermittent sound,...
Hello all, I've been lurking for a while and have finally found the free time (sort of) to take a shot at building Scott's Alice microphone. After dremel-ing...
First thing I'd look for is for a leaky capacitor. That would tend to intermittently let some DC through - most likely one of the electrolytics. -Scott ... --...
Hello, I was wondering if someone could point me in the direction of some good information on testing and calibrating an electret condenser microphone. I am in...
Hi, For those looking for information on Primo, it can be found at www.primomic.com . Nakamichi CM-300 uses the EM-21 and EM-23. SNR is 70 dB, a bit more than...
Hello Ken, ... Would this work with and without DC on the mic/15K node? I mean, would it also work when using a 3-wire hookup? (3-wire configuration only has...
I'm curious as to what, if any, differences there would be - sonically - with various manufactuers versions of the 2N4416 Jfet. I see, offhand, that it's made...
But where can we buy them? A few days ago I went to the afore mentioned site and sent them an email requesting info. Thus far, crickets. I also noticed the...
I'm wondering if any of you have built preamps for your mics? I'm curious to try, as the cheapo preamps's I have sound, well, cheap. I've looked at the...
If you are Looking for a High quality DIY Mic pre-amp do a Google search for the "Green Pre amp" as it is an extremely High quality Preamp but is Fairly simple...
Hmm. Thanks for the heads up on the ina217 I had checked mouser and saw they were "on order", however I thought I found them in stock at digikey. However, a...
Also check the datasheets of the ina217. There are some examples of mic-preamps in there too that are better than the one you linked to. The ina217 seems to be...
