For decades, vibrant microphones have now been wired with the voice coil attached to the primary of the microphone's transformer, and not referenced to soil (‘floating'). The microphone's case is normally connected to the wire shield, which can be linked to the mike amplifier's soil (see Rane's site for more discussion).
By and big, dynamic microphones are extremely quiet units consequently of the mixture of transformer solitude and healthy, hanging indication lines for the duration of, in addition to shielded, humbucking coils.
