This may be something basic that I've missed, but I'm looking for a straight forward explanation of capsule capacitance.
Does a capsule with higher capacitance have a louder output? I found the volume difference between a CK12 styled capsule and an M7 capsule in a G7 microphone to be quite considerable, and it was my understanding that the CK12 had a higher capacitance. What makes the CK12 louder than the M7?
When I look at this page however, http://recordinghacks.com/capsules/ the CK12 capsules vary in capacitance a lot, and the M7 capsules sit right in the middle of them capacitance wise.
Even within the CK12 styled capsules, the range is from 64.4 pF (RK-12) to 97.4 pF (ADK GK12), so does that mean the RK-12 would have less output than the ADK GK12?
Even if I compared to AK12 to the RK12 (since they're in the same price range) there's a difference. Does the 3 micron diaghram make a difference compared to the 6 micron? Will the RK12 have less output than the AK12?
What are we looking for with capacitance? Is higher better? Is lower better? Where does Tim's CT12 capacitance sit ?
In the pursuit of a quiet tube mic, having a low output capsule seems to make it harder with noise, even when you have the lowest noise tube you can get your hands on, and the circuit is cleaned to perfection.
I'm ignoring the fact that we may choose a particular capsule for it's tone for now, just so I can understand things better.
I've searched and read through threads here, and I've read some of the "microphones" document from Neumann, but I'm still not that clear on the topic.
