Both. Reducing the distance and relaxing tension both tend to make the diaphragm closer to the backplate, which increases the capacitance, and thus the output level. However it also results in lowering the resonant frequency and increase damping, so the mic will lose HF and be bass heavy.I first followed the directions and had the distance between the mylar and the backplate at 2 thou. I reduced it to 1 thou and lowered the tension of the mylar, and the output went up by about 20db. Does anybody know if the was the distance or tension that caused the change in output?
It's the recipe used to make sub-sero noise microphones, that require electronic EQ.
