[Elecraft] Microphone Setup Confusion

[Alan Geller]

Is what Elecraft calls mike “bias” in the K3 and K3s Owners handbooks 
Equivalent to the “48 volt ghost voltage” required for condenser mikes et al
In the broadcast and music industry ?

It is mentioned that “mike bias” needs to to be turned on for condenser type mikes
But off for dynamic types which is also equivalent for the more common 
Term  “48 volt ghost voltage”

Thanks for any help
