What is a condensor mic used for ?

Question

What is the advantage of using a condensor mic to record a live concert?

Is it a good idea to use it with a mini disc recorder?

Do they pick up the bass well at a concert?

Answer 1

They are far more sensitive than dynamic mics - dynamic mics must be very close to the source to work well. Mini disk should work well for a concert, depending on the mic, the bass might be picked up ok, but several different mics in different positions provide the best results.
