I recently aquired a audio technica lp1240 turntable system and I was just wondering the below:

a) you can attach a microphone to the turntable, and which mic is the best to use
b) what sort of speakers should be hooked up to the turntables for the best sound
and
c) I know you can take vinyl records and put the on as a digital file, but can you take a digital file from your computer and play it through the decks? Thanks. did not match with any Web results.
