This thread has digressed. But the original poster asked what is a "P.A." mic - its one used on stage such as what is used by singers at concerts. What is "line level" that is usually considered 0db. PC Sound cards required approximately line level input. A regular P.A. type mic, such as a Shure SM58, has a very low level signal and thus requires amplification to the line level to operate or operate properly with a PC.
Thanks for getting us back on track Jack. I'm leaving this thread on you since you have more experience with recording and such. It appears the OP needs some training on audio if he expects to capture the quality he may need. I wouldn't know what frequency a baritone even starts.
I've heard good things about Blue Snowball Mics.......that comes from my vice of reading reviews on review websites, not any actual experience. It could be a piece of garbage for all I know. I also don't know if that is the type of mic you need.
Plus, if you have any nails sticking up anywhere, you can use the SM58 to drive them flush after (or before) your recording session. Those MS58s are built like tanks. I'm currently using EV PL80s. EV's answer to the SM58.
If I were going for quality audio, I'd go with a good quality XLR mic, preamp, and a digital interface for the computer. It'll cost more, but the sound can be great - PLUS - you'll be able to use the mics for recording or live performance without a computer. There are some high quality USB mics available like the Blue brand, but I don't like my mics tied to a USB port all the time.
The "signal" from a mic or from an MP3 player to a headset is the actual audio. In tech terms it is a "signal".
The output of a PC mic is approximately -4dB which is a relatively high signal level. The output from a standard P.A. type mic, such as the SM58 is -54Db (or 1.8mv) which is not enough for a PC sound card and the reason it needs a preamp, to amplify it up to a useable leve for the PC. A USB mic has the proper levels, you connect it to a USB port on your PC and you record with that as you would with a mic connected to the "mic input" on the PC.

In the old days before USB, we had to plug our mics directly into our sound cards mic jack.... I still have a $30 mic from those days somewhere.
Good bass line, but I don't respond to jokes with approval or disapproval only posts just to pad my stats, that's just how I roll.
That Shure SM5x series seems to be quite popular for the OP's purpose.
I use a Logitech AK5370 standing mic for all my voice/singing, but I am not trying to make a record.
