Right,but condenser mics usually need phantom power which, for a simple
setup, would be a bit much. SM58s are nearly indestructible and also
don't have as much proximity effect as the speaker's distance from the
mic varies. Was just trying to avoid going to far into the weeds, but I
seem to be up to my knees already <smile> Speaking of condensors and
phantom power, I think many cheap 'windows' mics get 5v power from the
sound card which is why they won't work on the mac. At least I thought I
had read that somewhere. Sort of a non-standard phantom power.

Take care.

This has been covered before but generally there are three audio signal levels:
speaker, line and mic. Obviously speakers are high powered while line level is
the output you typically get from a CD player (not headphone) or DVD player.
Mic levels are very very tiny. There is a diaphragm which vibrates with the
sound in the air and moves a tiny coil of wire near a magnet, generating a very
small electrical signal. All this means is that your Mac has a line-in jack
expecting line-level signals while mics produce something much much smaller. So
to use most mics with a mac you need something called a pre-amp. Pre-amps take
the tiny mic signal and, without adding a lot of noise, boost it up a couple
multiples.
So if all you want is a mic to skype with you could just go with some USB
all-in-one. If you want better quality then you'll want to get a real mic and a
preamp. Something cheap like this:

and a basic Shure SM58 would be a good start.

Hi all.
I have been trying with more microphones, if I could use an external
microphone. I found one that I could connect to the line in, but the
recordings is very low. I have a mac book pro with one mic/headphone
and then I have the line in. Is there any way I could use the
headphone/mic for an external mic.
Best regards Annie.
