At your own risk.
One way is connecting many microphones in series, christmass tree bulb way.
Many female XLRs connected to one male XLR pins 2, 3-2, 3-2, 3,2 , 3.
The signals are added, so,the signal can be stronger.
Impedances are added so the total impedance is increased.
This means when they are connected to an input transformer the Pleiades filter cutoff frequency increases.
This may remove bass heaviness from many reasons including Fletcher-Munson and voice effort curves. So the reproduction may be flat from vocal chords of singers for example to listener's brain.
Suitable mics can be moving coil omnidirectional.
Some of them may be connected out of phase and this will give a noise canceling effect. One can also have a parametric bass cut according to how close together the out of phase mics are brought.
This can make it possible to record outdoors at low noise and tangle same time have the fabulous acoustics of few reflections and only very few close ones.
