I just did a comparion of my "bodyless" AT822 vs some Franken Naks.
Both mics were run XY (90 degrees, coincident) into line in on Mindisc. Gain was set to full (30/30) and HiSP mode (256 kbps). +6dB was added to the AT822 and +12dB was added to the Naks.
The "bodyless" AT822 was just the elements (still in the head) of the 822 mic, with a 4.7k source resistor and a standard 9V battery box.
The artist is Shannon Lyon (shannonlyon.net), acoustic guitar and voice, recorded about 10' from the PA speakers on an outdoor patio.
Enjoy!

Oh yeah, go to about 1min into clip. Sorry...

Thanks Richard. Listening now.
Just a quick note...the urls above are correct, but clicking on them downloads the same file at822 file.

Really interesting comparison. I'm surprised, but I like the sound of the 822 a good deal better than the Naks.

Ditto.

Fixed. Sorry...

Thanks for posting this!
Have you measured the angle on the AT822? I thought it was supposed to be 110°.

Yeah, I took it apart and it is 110 degrees. So, not an *exact* test, but as good as you're going to get :).

Didn't mean to be critical of the test, just wanted to get independent confirmation of the 110° figure since I'm too chicken to rip apart my own AT822, at least not yet.
Do you have a sense of how much sonic improvement one might get by adding the resistor and battery box?

I don't understand your question.
AT822 *already* has added resistor and battery box. (Ie., it is two-wire, but with a 4.7k on the source of the FET to prevent overload.) The Naks have "3-wire" battery box.
Oh, I see. You're asking if you can improve your AT822 by ripping out the electronics and just running it with a battery box? Not much is my guess. There is just a single buffer transistor between the FET and the XLR output. In fact, having that buffer in there might be better for driving long cables. Also, you might be able to drive line transformers too, if you need gain. I think I'm getting maybe 10dB gain out of the line-in on my Minidisc. If you're running a NJB3 line-in, then you'll need a pre or some transformers.
Anyway, enjoy!
