and unless you are trying for sonic nirvana (which is unlikely in this
circumstance), use a close-range dynamic cardiod mic like an
Electrovoice RE-20, a Shure SM-7, or a Samson Q7.

The tech gods will probably scold me here if the RE-20 and SM-7's
aren't dynamics, but any of these three will capture close sound with
good quality, and reject most of the room stuff.
