Oh I Thought I Had
Ya, it's funny, I enjoyed this link so much I was sure I'd left a post about it, but ... wait... I'm leaving one right now!
Fabulous details about condenser microphones. Great information!
Druid, leave me your bank information, I want to name you as a beneficiary of a microphone from my collection when the time comes.

This Time I Meant What I Said
A month ago I told how much I enjoy DHR's link on Electret Mics.
Since then I have watched many YouTube videos in review of the featured mic, a Neewer NW-700.
It is the most informative look inside the "secrets" of designing a professional condenser microphone using electrets rather than hand-made capsules.
The better YouTube video reviews demonstrate how good this $15 microphone is!
I was about to order mine when I spotted a NW-800, and found a comparison video which very well shows that the NW-800 sounds ever so slightly better than the NW-700.
So today I spent $24.00 and will have the NW-800 in time for the 5th-Saturday of the month broadcast of Blare OnAir from TeamSpeak Room.
To many buyers these microphones cause massive confusion because they require phantom power, and not everyone has a clue what that is, in which case their microphones fail to work.
Blanket offer to those who can't get their Neewer mics to work... I will buy them from you at 20% of the purchase price.

I am assuming your mixer has phantom power?

Phantom Power In House
DHR expects that the audio mixer might have phantom power built-in, and...
Yes, many mixers do have it.
Case in point right over here next to the cottage cheese container now serving as a small waste basket, our RDL-RU-MX4 Mixer provides 24 Volts phantom power, whereas the Neewer mics specify 48 V phantom power... but I think there are fixes.
What do you know about fixes?

What do you know about fixes? I found this: "In most cases, these different levels should not cause concern. Most mics work fine over the voltage range of 12-48 volts, although many mic manufacturers specify 48 volts for best performance, and some mics may be more problematic than others when encountering lower levels of phantom power—you may notice some loss of output or sensitivity with lower voltages. In any case, a lower voltage won’t damage the mic, so you can always see for yourself if a lower voltage will work." |

You May Very Well Be Right
On the subject of Phantom Powers of 24 or 48 Volts DHR reports: "I found this: "In most cases, these different levels should not cause concern. Most mics work fine over the voltage range of 12-48 volts, although many mic manufacturers specify 48 volts for best performance, and some mics may be more problematic than others when encountering lower levels of phantom power—you may notice some loss of output or sensitivity with lower voltages. In any case, a lower voltage won’t damage the mic, so you can always see for yourself if a lower voltage will work.""
I expect that this will prove true, recalling from one of the more believable YouTube reviews that the actual Voltage supplied by the Neewer Phantom Power Box (an optional accessory) is 18 Volts.
Perhaps the application sheet that comes with the mic will have more to say about it.

Phantom Preparations
Today the Neewer NW-800 condenser microphone was shipped, due to arrive Friday.
Having watched many YouTube reviews and scrolled through user comments at Amazon, we know that the microphone performs best with a 48V phantom supply, but, oddly, will work in un-balanced mode with a consumer 5-Volt power supply, which some soundcards and cameras provide.
With only 5-Volts the level is reduced to the degree that noise generation becomes noticeable when turning up the level to compensate.
From having read the Radio World Review of the NW-700 I gather that a voltage regulator is built into these mics, and this might serve to make my 24 VDC phantom supply adequate to get decent performance. I don't think it will do any harm.
The reviews say that the manual is sort of cheesy.

Not Buyer's Remorse
Seeing the package on the floor of our Parade Review Stand (formerly the front porch) we did not notify bomb squad, since we were expecting the NW-800 and realized it was likely the microphone... although the delivery person had made a hasty retreat.
The outer box was smaller than expected... on YouTube reviews other people got their microphones in larger cartons.
The inner box seemed small also, and had no mention of the model number, only "CONDENSER MICROPHONE".
The microphone itself is physically very high quality... the finely machined aluminum body can easily be dissembled for inspection, and the circuit card is of high build quality consisting of micro-miniature surface-mount parts too small to see without the Hubble Telescope.
Getting into the capsule cage requires removal of 2-screws which we did not tackle as of yet.
The included shock-mount fit neatly on our desk stand and connected by XLR to our RDL RU-MX4 Mixer with 24 V Phantom Power enabled.
Immediately we registered on the LED audio level indicators and began recording blather which will be included in a forthcoming episode of Blare OnAir.
All I can say is what got said on that upcoming program.
You are welcome to hang around until such time.

This reminds me of a Sansui cassette deck I once purchased while in the world's largest nuclear powered navy. The manual stated that "the heads were polished to a high luster to reproduce the brilliance in your music." How's that for a pitch?

Don't Under-Rate High Luster
I have high luster to thank for my success in the recording business.

The Curtain Parts
Having spent quality time evaluating the new Neewer NW-800 Electret Condenser Microphone we are planning to part the part 15 curtain to reveal our findings to the woild.
Toward this end a small stage has been built upon which the gold-grilled microphone will stand in its shocking-mount, displayed between actual tiny curtains that will part from the center, swishing left and right. We considered having a rising curtain, but side-to-side looks better on video. There is no video, except in the radio mind.
Last night we aired a demonstration edition of Blare OnAir demonstrating the Neewer side-by-side with our fabled Alpmic in its chrome drain-pipe, but that program is not linked anywhere and need not be mentioned now.
Two planned events lay ahead... on the 5th Saturday of April on the 29th Blare OnAir will broadcast live from the TeamSpeak Open Room starting between 7 and 8 PM EDT, all of you are invited to log in and join us for your judgement of the Neewer NW-800.
Then a week later on Saturday May 6th at the ALPB TeamSpeak Meeting the Neewer will be used throughout the meeting with occasional fade to the Alpmic for demonstration purposes.
Carrying hobby radio into the next century would be premature to say.
