Hello my friend. I figured out same technics as you, but when I connect this mic to my external audio interface Scarlett 4i4 I have very very very low signal without battery. Even if phantom power is on. Can you advice whats wrong and how to make it operate without battery?
I believe it's a bias voltage issue. Check the voltage coming from the jack without wiring the microphone. We need between 1.5V to 2.5V (1.5V is typical for this capsule). If it's below 1.5V, it's under-biased and proportionally decreases the output signal. If it is too high cause degradation in sound and may damage the capsule.
After I got the microphone, I mistakenly inserted the LR44 battery with reverse polarity inside the capsule and turned on the switch. Obviously, it didn't work, so after realizing my mistake, I corrected it by installing the battery with the correct polarity. It works, but there is a constant static noise in the recordings. Do you think I might have somehow damaged the circuitry inside the capsule?
Static noise are common in every microphone and it's there. When it's getting too loud then there is a problem maybe somewhere in the cabling or connector based issues. You can use audacity to clean up the audio or use ai based tools like rtx voice or atleast you can turn on noise reduction in the audio control panel of your personal computer. Check out my mic building video there I explained some of the audio recording tips and I made that mic for just around $1.77 and which sounds great with my recording tips.
