Connecting many microphones in parallel

At your own risk.


One could connect 2 or more microphones in parallel and sing to them. This means literally pin 1 with pin 1, pin 2 with pin 2 etc.


This would create an effective large diaphragm but with the transient response of a small one and sensitivity of a large.


So the combined microphone could be further away and still capture the same percentage of the spherical waveform.


The voltage would theoretically be the some but current double (for 2 mics) , ie impedance half so less noise.


The array would further increase directionality if reciprocity with array speakers apply.


In fact the idea is very similar to many small speakers driving air one next to the other, one aiding the radiation impedance of the other, increasing efficiency. Also there is increased bass, less excursion distortion, and directionality.
