Thanks all, that's given me useful illumination but unfortunately some confusion. RC> if you use the usual 4-resistor diffamp circuit, you throw away about ......
[JL] The i/p load impedance of the Sony D50 is quoted as 22k so maybe I could use a slight step-up ratio to the Xformer (IE more level & impedance) [RL] Using...

The only possible advantage is if due to the unpredictable nature of what you are recording in terms of level you may have an advantage in recording ...
I am attempting to make some sphere mics based on characteristics of the Shoeps designs. They have such a good reputation in our discussions that I figure its...
I no longer have access to the Schoeps KFM-6u, but I used one for over 10 years or so on probably over 500 recordings. I never really measured where the...

I just picked up a SASS PMkII, and am a bit disappointed in the amount of self-noise it exhibits. It seems much louder than the 21dba that is listed. I'm...
Hi Bryan-- Thanks for the encouragement. I remember reading of your lost access. I believe the KFM-6u is an older unit so if you don't recall its capsules...
... Scott, I just ignored your kind and well-meant advice and took the works out of a disposable camera. They do indeed pack a punch. After peeling myself from...
... The Signal when measuring signal to noise is normally 94 dB SPL @ 1 Khz. The remaining noise is therefore 94 - 65 = 29 dB Weighting curves A,B,C are the...

Go on the prodigy-pro forum and check the META-META about the microphone design. I think everything is there.... hours of addictive reading let me warn you!!...

Primo EM-158 would also be a good candidate for PIP setup. I've built a T mic with those caps for my M-audio MTII and without any mods it's far better than the...
Hi ! I've been ordering parts for some Alice mic and some TSB165 mic experimenting. I've been shocked by the price of the little resistor needed for almost any...
Using 2 capsules in parallel should theoretically help your signal to noise ratio. Signal is in phase (or polarity), but noise would be of random phase, so...
The Schoeps mic was phantom powered only. My Mackie 1202 powered it quite well after the specially modified Millenia preamp gave up the ghost. As to the...
