While I agree with Jim, K9YC on this. Some dynamic mikes I've encountered do use a transformer to get the voltage level from the very low impedance Z element to a respectable output value. Running a bit of DC through the transformer on the secondary side could tend to cause some DC saturation.
Exactly right, Bob. And Don Wilhelm reminded me that some mics used with a K2 didn't like bias. That can, of course, depend strongly on the value of the bias source resistance.
