Title: Panasonic WM mic capsules
Post by: Jim McKeveny on December 14, 2011, 07:38:56 am
Wasn't the Panasonic WM60/61 used in entry-level measurement mics? They are discontinued now, and I wonder what will replace them?

They're still available, at least on Ebay:

Here's a source for direct replacements:

But I'm not sure there would be much sense in building a measurement mic these days, what with the proliferation of cheap "measurement" microphones with 'good enough' performance.

Maybe I'm wrong.

Hi,

WM-61B (pin version) is discontinued. But the direct solder version is still available. Check out the Linkwitz (http://www.linkwitzlab.com/sys_test.htm#Mic) web site for helpful modifications. Also here (http://www.johncon.com/john/wm61a/).

Some friends, at Queens University Dublin, have been using an array of  BSWA (http://www.bswa-tech.com/products-microphone.htm) mic capsules. The price was pretty good, and the capsules are significantly better than the WM. BSWA is the B&K of China.

Tom is correct in saying that it is hardly worth the effort to build your own mic, especially if your measurement software allows the use of a calibration file. Unless you are looking at an array of mics, then it is much cheaper.

Some links you might find useful.

I have been toying with the idea of using them as semi-disposable string mics. Of course I would ease 1 or 2 into my usual big package of MKE2's & WL183's as a test.

somewhere out there is a pair of wav files from a WM61vs4000 series shootout. It's a guitar recording with the mics as close to coincident as is feasible. In a blind AB, listening on HR624s, I could not tell the difference. My lighting guy picked the WM as the money mic in the same test.
