Why do some people turn there mics upside down, or hanging when recording?

wow meriphew, I love the intro to your site!!!

Just FYI - my Marshall V69 tube microphone recommends the "upside down" position because of the heat rising from the tube. As usual, Fletcher has it right.

if the diaphragms of classic condensers weren't gold, what material(s) were used?

Well there were 'nickel diaphragm' [hell, there still are, Gefell makes a couple of models that use nickel diaphragms] microphones... but what I was talking about was the difference between the gold being sputtered on mylar vs. the gold having been sputtered on PVC. I was talking about the backing material to which the gold had been adhered.

Also, is there any predictable pattern to the sound variance you get when the mic is inverted or not? Is inverted generally better, or is it one of those things that varies, depending on the acoustic space, the material, and taste?

It's all to taste. It also depends on how you position the mic and how the singer moves when singing [and they all move].

To the person who mentioned that their "V69" should be upside down due to heat... don't worry about it. While the Chinese capsules are indeed less rugged than some, the fact of the matter is that the tube in the "V69" isn't going to throw enough heat to become a problem.

A VF-14 tube, as can be found in an old Neumann U-47 will throw enough heat... but things like the 6072 found in the ELA M 251 E or the C-12 don't. I highly doubt whatever they put into the V69 will get close to throwing enough heat to do any damage worth talking about.

Thanks, Fletcher. Any idea how old PVC is, as a material? I was under the impression that PVC was developed in WWII as a replacement for Bakelite, but it sounds like I'm wrong.-Richie

Well the first Neumann microphones were called the CMV-3 and were made in 1928... they were condenser microphones that employed gold sputtered PVC as diaphragm material. I have no idea when PVC was invented... but it musta been around prior to 1928.

More Neumann History...

... but it musta been around prior to 1928.

Approx. 1912 give or take a few development years.
