There is NO problem connecting a pro dynamic mic, which is balanced, to 
an unbalanced input. All it takes is a simple adapter, XL-female to 
1/8-in TRS plug. Connect pin 2 to the TRS tip, pins 1 and 3 to the TRS 
sleeve. Make sure that Bias is OFF -- dynamic mics don't like DC.

There is no easy way to connect a pro balanced ELECTRET mic to an 
unbalanced input.
