Check out this cool article by Aaron Lyon over at Matthew Mcglynn's outstanding website RECORDINGHACKS.COM : http://goo.gl/E9YlO Seven sub-$200 microphones are...
... In hopes of making this feature even more useful & interesting for the micbuilders crowd, I'll be updating the mic profile pages of the 7 contenders to...
... TSC-1 & TSC-2 are electrets so you don't need to mess with polarizing voltage. You can generally believe their sensitivity specs. eg TSC-2 -35dB ref...
sorry richard, but tsc 1 and 2 are true condensor, and not electret, so you have to apply a polarisation voltage. (i bought a couple of tsc 1s) Â umashankar i...
All, I recently acquired a Keithley picoamp ammeter, would it be possible to directly measurt the output of electret capsules through the 1G resistor into the...
To my knowledge, Keithley picoammeters do only DC measurements. The output of a condenser capsule (electret or externally biased) is AC. ... [Non-text portions...
The latest diyaudio newsletter has a rave review of a $89 pocket oscilloscope by Jan Didden, editor/publisher of Linear Audio. "The base model I got has a 1MHz...
... Which model? The 610C can be used in amplifier mode 10^15 Ohms in parallel with 20pF input with frequency responses up to 40kHz depending on gain. The...
A 1Mhz oscilloscope is not worth spending money on. Sorry. I encountered an tens MHz parasitic generation in my pretty simple audio circuit - I'm lucky t have...
... Mike Rooke asked a related question and I thoughtI would clarify the above, because I think it's an important point. Acoustic pressure does work on the...
I don't know if the real question is the charge value, or the equivalent voltage an externally-biased capsule of identical parameters would need. Sure, there...
... Th original questions were only concerning the DC voltage. I didn't think it was necessary to differentiate between pushing and pulling either. The...
Hello Everyone I disagree. A hand held 1 meg scope can be useful but, If the question is, "is that all the scope I need?", the answer is likely no. You should...
All I know is the stuff I use melts when sputtered with gold, or carbon and when its finally placed in the SEM with the beam voltage cranked up "to 11" it...
... The beam is moving electrons, their deflection in a static E field is easily calculated. So I guess this is a way to measure the field, albeit a little...
I'm curretly planning on building a binaural head with wm-61a capsules. I want to power these with P48 power. I've come across a schematic for a P48 adapter...
The capacitors C1 & C4 should be electrolytic types or tantalum types with a 16 volt minimum working voltage. please note that the symbols are upside down but...
... Someone recently posted his test results that showed a definite increase in sensitivity vs. voltage supply. Fortunately the sensitivity grows less rapidly...
Hi mates, my goal is to feed a dslr camera mic input with live audio from H2n line/headphones-out. I tried but got serious clipping and distortions, so it...
The headphone output is generally quite low (<32ohms) and the mic input is higher than 600ohms, so there's some latitude with the values. L-pads are very...
They are not quite different. Rather, they are intended for people having difficulties dealing with other than power of 10 numbers ;-). Regards, Â Sergei....
@vivaldivi, Re: "I've just found quite different values on the page" You asked for 25dB attenuation. With 10k/100R, it's 40dB. ... [Non-text portions of this...
True, the noise this circuit shows is the best it can get. i´ve use it a lot, WM-61A is not precisely a quiet mic, i never got to measure nothing lower than...
... This sounds like a very nice way to go. But you might want to see if you can get some Primo EM-158 capsules, which are approximately the same dimensions...
