Aw, dirty pool, making me think on an empty stomach ;-))

And now that I do, it probably doesn't solve anything wrt to a mains
fault. I suggested it as Michael mentioned the possibility of a 48V
shock. Making a controlled 48V within the mic with an SMPS from
LV was just a thought. It is just as possible to have a fault on a LV
supply. But, specifically, if the current-limiting of a 48V supply was
somehow bypassed, it would be more likely to shock than unlimited
5V

For any situation to become hazardous it would take more than one
factor. eg if the chassis became live there and was no good ground,
RCD and/or fuse, the mic was not insulated, in the left hand etc

To be absolutely safe every potential (no pun intended) failure point
should be addressed
