I'm going to build an MS mic eventually, but for now I tried a pair of AT853 from Soundprofessionals.com. The price of these mics is $79 apiece (with just bare...

I too would welcome a audio centered text that gives the nuts and bolts training in the electronics. In the past I have used the Amateur Radio Handbook to give...
Thank much Bob and Eric for providing the useful sensitivity numbers on these popular mics. Dan Dugan of the naturerecordist list has confirmed that one can...
Ah, your pdf is probably the source I quoted from earlier. There are two spec sheets on their caps. 42.2 mV/Pa sensitivity would be superb. I know it makes...
Dear Neil, I was trying to contact you privately, but could not figure out how to do it... In the uploaded files I paid attention that there is a picture of my...
I just checked the voltage on my AT853 (Linkwitz modified) battery box. It sounds OK, and it did not seem to overload. But I'm only getting approx 1.5V...

Hi, I'd like to hookup a WM61a Linkwitz capsule to my diy mic preamp. My mic preamp uses a + - 4.2V supply (currently even no more than +- 3V, and the OPA2228...

Richard, If your AT853 is "Linkwitz modified", is not your 10k resistor in fact the source resistor? It makes a difference because the resistor will have more...

I have seen a few designs around this capsule that involve potting the rear electrical connections with epoxy. In looking at the back end close it appears that...
