Movie prop or real microphone?

[rock soderstrom]

I just saw this microphone in a movie. Prop or real product? If real, does anyone know the productname/ manufacturer?

Thsoe are real mics, can't remember who makes them, but they are a thing.

It's a microphone made by "Ear Trumpet Labs". If I'm not mistaken, the owner is also a member here and once commented on it's capsules origin. You can find the product page here: Myrtle — Ear Trumpet Labs

Ahh, you right. Thanks a lot!

Thank you very much, I have just found that too. I had also heard the company name before. Now I can remember again. I'm getting old...

Nice microphone, I like this style.

It caught my eye not only because of the look, but also because of the long cable to the FET headamp, which is probably in the base of the mic.

In another recent thread it was just mentioned to mount the FET directly to the capsule.

I don't know how it was done here, but I suspect that it was done more conventionally and that the very long cable to the headamp is shielded.

It seems to work.

Would shielded leads from the capsule to the grid/gate in a conventional mic body score points?

If it’s not necessary I would not do it. I think the added capacitance (between wire and shield) is bad.
There are some very good coax cables with minimal capacitance but still it’s there. And normally you don’t need shielding in a proper body.

Tried it, without using reason first. Shielding is in close proximity to the signal wires, it adds capacity, degrades s/n significantly. Also the whole cable starts behaving as a mic of sorts. I've seen people twist capsule leads, not advisable for the same reason. Capsule leads should be further apart, not in close proximity to ground either. Avoid touching grille, passing through tight holes without some spacer.

Dang, we posted the same exact second

Thank you both. Thank you also for confirming my concerns. These are probably the reasons why this is not done by the other well-known manufacturers.

What is best to use, teflon tubes?

Already answered but yeah it's an Ear Trumpet Labs microphone. I think a lot of them (maybe most if not all?) use the TSB2555 capsule. I'm getting this information from the modules listed on Recording Hacks (and making assumptions based on the fact that a lot of them have very similar frequency responses).

Looks like they've based it on the Astatic D-104, in a suspension mount.

I like this one. Looks like a copy of an old carbon mic.
