and a (lower) sensitivity of 5.6mV/Pa (high mV/Pa #
[sensitivity.output] is good; low dB(A) # [self noise] is good.)
compare to:
Panasonic WM61a capsule 32.5 dB(A)* 18 mV/Pa **
spec sheet: http://tinyurl.com/8g4l9
Cost $16.21 for 10 + shipppiing http://www.digikey.com/ and enter
"wm-61a" into parts search.
You can solder a workable set to run on MD/HiMD plug in power for a
few bucks more http://webpages.charter.net/tidmarsh/binmic/
*Based on Eric B's test on file on the micbuilders list.
http://tinyurl.com/8tkt4 **Is this sensitivity number right? Eric's
test seems to confirm Panasonic's figure of (0dB=1V/Pa, 1kHz)
-35+/-4dB.
I need to learn how to make this conversion.
and for reference:
ShureWL-183 22 dB(A) 29 mV/Pa
