Audio Technica AT2010 High Voltage Demo Explained

[jello07032]

that is really surprising

[forwardbias]

Farraday Cage, if that mic is all metal casing, that metal case carried away the current safely from the sensitive electronics inside. Simiple Farraday Cage, from the late 1800's Energise a man, inside a metal cage, even if millions of volts, the man inside is safe. Current is carried away through that cage. Farraday's Law. Spelled Farraday wrong I know.

[paintballengineer]

the "p48" will stand for 48 volt phantom power

[3dsniper]

it has a aluminium body doesn't it?

The high voltage went into the metal mesh, into the body, the body conducted it into the aluminium plate and then onto the ground.

I liked seeing how the wire didn't appear to make a good conection with the.. plumbob it was called? you didn't strip the insulation did you? ;)

also, I'd like one of those power supplies.

too bad our grid connection is only 3fase, 22amp. though that could be nice..

[ShovelAndRake]

Into ground? Electrons move from negative to positive, don't they?

[3dsniper]

@ShovelAndRake in practice they do, but we usually speak of them going in the other direction. but the clue was that the metal body and mesh around the electronics had a lower resistance, so almost none of the electrons took the path of the electronics

[cerealguy500]

How can you shove 75kw through thin magnet wire?

[Physicsduck]

Because it's only 1 Amp. 75kW = 75kV @ 1A. That wire would handle 10 amps with ease.

[DECOFRANCE]

@cerealguy500 remember current is inversely proportional to the voltage

amplifying the voltage causes the current to became very small (Power stille thesame 75KW). the wires are more affected by the amount of current

flowing in it..(voltage amount doenst affected the wire that much)

[juniortore]

it was better when you had the microphone, I could actually hear you.

[NeeKroVal]

hook that thing up to a go cart

[paronfisk]

FAKE!!! :D

[nanu0332]

u r just a noob!

[paronfisk]

@nanu0332 eat me!

[sarick1]

I think I know what is happening. It's design is like a faraday cage protecting the inside electronics.

The microphone itself has a wire mesh at the top connected to a metallic housing. When taking the path of least resistance the order should pass right over the sensitive internal workings.

Mesh piece covering microphone > Connected to metal body > ground plate.

It seems any device that has a low resistance housing surrounding it that is connected should be relativity immune.

[TimeElf1]

Hey Duck is that one of those indestructible mikes? The ones that you can drop down the stairs and still use? If so maybe you could pound nails with it.

[thegeekgroup]

No, it's not. It's actually a very delicate studio condenser mic. Pounding nails would be a bad idea.

[devhook23]

@thegeekgroup we never saw the second camera cut

[JOBGG16]

@TimeElf1 I heard Sure SM58 are tested on dropping from 2m or so, but even though the audio circuitry and everything survive, the top cover will still bend considerably. It will work, but it will be really ugly and dented on the top (realized that when mine fell out of my pocket (0.5m) onto the street.

[coondogtheman1234]

fry a wireless mic so we can hear what it sounds like on its last leg, if it actually fries.

[jeffsadowski]

Sounds better in this video it was chopping in the previous video. Either you turned off the chop out in this video or ... something

[DidntKnowWhatToPut1]

Can't wait for this show, you can have people donate things to be zapped too

[m3sca1]

well its got like its own farady cage on top-why would it NOT work after the zapping?

[Physicsduck]

A: Because the faraday cage isn't complete (remember, big hole in the bottom with leads going from the edge to the delicate electronics inside) and is therefore useless.

B: Because the FIELD alone is enough to kill most mics. Especially a delicate condenser mic.

[sparkyprojects]

But as soon as you place it on the plate, you complete the cage, even if it was on an insulating plate, the arcs would rather go to ground than back up into the mic that is already at the potential of the arc.

As for the electronics, they are also shielded in that the potential difference is just about zero

True that the field could destroy delicate electronics, but having a good solid metal case helps a lot.

btw, is that top section metal too ?

the mic element etc are double shielded if it is

[harpbloke]

great vid.

thanks

[HighVoltageScience]

You need to get some x ray wire for that thing.

[pt2091]

That was freakin awesome.

[cheeseboat15]

I never said it was fake =3

I knew exactly how it worked

~feels smart~
