Best way to damp the body of an Octava MK-319

Can anybody provide step by step directions for how to do this? I've read about using silicon calking but where does it go?

Spray the body with a can of that liquid rubber stuff. You can choose black or white.

Yes.

Especially covering the entire capsule, until the stuff comes oozing out of the headbasket. Do not remove any of the silicon, just let it drip to the floor if necessary. The floor probably needs this damping as well.

Then it will be properly dampened.

LOL.

Spray rubber, great idea!

I used some electrical grade caulking on the inside of the body and it worked very well.

I packed the inside of my 219s with thin open cell foam. Works well.

I pack my ribbon mic cases with torn-up cloth.

Thanks everybody but I really need a how to do this for dummys. In other words step by step...first take the mic apart etc. Does the damping material just fill the spaces between the circuit board and the bottom barrel of the mic or what?

Yes, more or less; the concept is to dampen the vibration of the body by faking a sort of inner lining stabilizing the metal body tube from top to bottom.

Again, I typically stuff scrap cloth (cotton T-shirt is good, or light denim) right up in the tube.

A good test is, plug the mic in and crank the gain; tap the body with yer fingernail.

Now, stuff the tube, do the test - it might go from sort of an easy "ping"-type sound, to a harder-to-get kinda deadened "thump".

OK, now it makes sense. Thanks.

What I did:

1) Take the body of the mic, most mics you just have to unscrew a part or two and it will come off easily.

2) Open the electrical grade caulking and glob some in the mic body. Get enough to dampen it but not too much to where you can't fit the electronics back into the body. I used a popcicle stick to evenly spread the caulking in the body.

3) Let it dry over night

4) Put mic back together!
