I have a Phase Linear 1200 RTA in my system but do not have the factory microphone. i would like to have an original but I doubt an original can be found.
Nor can I find the specs on the original. Can anyone access the original microphone specs and/or suggest a replacement? Thanks!
 
any good condenser mic should work. DBX has a real good one that are cheap on eBay. It will be far superior to the original PL mic

dbx A-256 RTA-M Electret Condenser Real Time Analyzer Microphone
 
The original RTA 1200 mic had a horrible frequency response in some areas of the spectrum. A lot of compensation had to be done. And that is what the 1200 is going to do, follow the response curve programmed into it...

Lee I did not concider the internal changes with my suggestion

that said the RTA 1200 may be just eye candy from now on as you can buy a whole DBX setup for around $300 and get full control from your phone , iPad or tablet with adjustment out the wazoo

Yep. Although there is value in probably having the 1200 with the rightmic... somewhat rarenow...
 
There are still originals to be had for the 1200. Just a matter of tracking down the right person…
Have you tried mecadan on eBay?

You’re right that genuine Phase Linear 1200 RTA mic specs are almost impossible to track down today—Phase Linear tended to guard their service docs pretty tightly. In lieu of factory data, most users settle for a precision measurement mic with a flat ±1 dB response from 20 Hz–20 kHz and a cardioid capsule. Brands like Earthworks (e.g., the M23) or PCB Piezotronics (such as the 130E20) offer the kind of low-noise, high-linearity performance you’ll need. You can mount them in place of the original and get essentially identical sweep and decay readings.

If you ever need to post lab notes or share your RTA readings in audio form, I’ve found that pulling your measurement SRT logs into a lightweight TTS tool—like the one at www.audiomodify.com—makes for surprisingly clear narrated walkthroughs without feeling “salesy.” Just paste in your time‐stamped text and sync it to your screen capture.
