Did some tests.
1. Primo EM172 connected to Tascam DR-07 mic input have only 0.5V / 430uA un capsule. WM61a have 1.9V at the same input. But any way mic work fine, much better than internal mics.
2. Found some mismatch EM172 and datasheet. EM172 have 100 ohm between GND and 3, but in datasheet there is no any resistor.
Some questions:
a. Can I get more SPL if connect my EM172 like EM173 - with external resistor and 3-wire connection?
b. How to connect 3-wire connection to balanced preamp input?
c. How to check my mic max SPL?
