“Nx” is usually a resistor “n”etwork. The mic is probably something else, it could be the M designators or even a “t”ransducer.
Anyway you may find that the remote uses a bunch of mics. Once you’re no longer trying to catch sound in a way that will be discernible to human ears it can become an order of magnitude cheaper to send several fraction of a cent mics into the 69 dsp channels every fucking soc has nowadays. You’re getting the silicon for free, might as well use it.
