So, does anyone here know what's inside a SMK-H8K/C? Is it just a diaphragm? Is there an amp? Does each mic have its own internal voltage regulator? Do they require phantom 48V? If you use less voltage, does it just reduce the mic sensitivity or does it affect the max SPL? How is the differential mic signal formed? Is it done by internal transformer, by connecting directly to the capsule or is there an amp with a differential output?
I'm trying to figure out what a minimum battery operated rig would be for using these mics. Any hints would be welcome.
