I am still trying to understand how to properly interface different microphones and other audio equipment with a 6400M. From what I currently understand, unlike other brand amateur radios which use a low ohm Z unbalanced microphone input, the 6400M microphone input has a BALANCED input. What is the 6400M microphone impedance input value? Is this the same standard 600 Ohm Z balanced input which is used for musical industry components ?

It is 600 ohms.  See the Spec tab on the FLEX-6400 product webpage.
