EEVblog

Doug Ford, former head designer at Rode Microphones explains 48V phantom powering of microphones and how it works.
There is a ton of stuff here:
Electrostatic and electromagnetic noise, differential amplifiers, common mode noise, transformer magnetisation current, JFET differential driver circuits, balanced impedances, phase splitters, miller capacitance and how it matters, and he explains how the Schoeps amplifier topology works.

Fantastic having an explaination of microphones directed at engineers rather than musicians. I would love some more on amplifier circuits in the same way.

Ahh....now it all makes sense. So all the Elvis moves on stage were involuntary electric shocks! :)

I loves Doug's little jabs at the audiophile market.

Having Doug on the show has been a great addition to the eevblog ever since the start when you were blowing up cheap-ass multimeters together :-) I think the microphone series is very worthwhile because i knew quite little about it before. Keep it up Dave & Doug!!

I remember when this was published, it all was Greek to me, and probably I half-watched it. Now, because of the EEVblog, and other inspirations like Fran and so many, many who stopped doing videos long ago, for some reason today this series was in my feed and it was like a revelation! Wait a minute - I can do these things, now! I can build it! I have the technology! Thank you Dave!

Thanks for getting Doug to do this series. This is my favorite so far because I have always wondered how phantom power works.

The learning never stops. Wished I took up sound engineering when I was in college. Thanks Dave for the series. Think you've hit another goldmine.

I love watching this series. As an audio engineer, it feels good to have a chance to go over the basics again! Also great to introduce newbies to audio engineering and electronics. Cheers for the uploads Dave.

Microphone design has proven to be a really deep and rich subject, even at a "basic" level!

[@EddyT1717]

I think this is the most engrossing video you have done yet Dave. You should get guests on more often. The years Doug has put in really show in the passionate way he talks about microphone design.

[@lothomillstone]

These videos are brilliant and exceptionally helpful. Doug's passion for his craft really shines through. Id love to see more of these videos. Get him back in the lab!

[@TheElectr0nicus]

Find those videos very interesting! Thank you a lot Doug and Dave!

[@UberAlphaSirus]

Great Series, I hope you get the next/last part uploaded soon.

[@LasseHuhtala]

Thanx again guys! I love learning about the innards of my every day tools. :-)

[@DreadFullMan]

Great series. Keep those mic videos coming :)

[@nerdydev]

I hope dough got a good few pints for this, very good series so far!

[@SianaGearz]

"Nobody likes transformers these days" - yeah thanks to Michael Bay!

[@stonail665]

Thank you both ...

[@marcdraco2189]

Doug Ford is my hero!

Even though I'm a mechanical engineer (well, almost) and know close to nothing about electronics (hope to change that), I still enjoy watching this series. It's entertaining to see how a person who knows a lot explains it in a witty way.
