Not being able to Record Voice into G5 w/ OS X 10.3.8?

[Soulstorm]

I just can't. I connnect a microphone into my G5's Line in (see my g5 specs in my sig) and I change the system sound preferences to Audio Line In input. And I cannot record my voice... Why? Is there something I misseD?

Mike voltage levels are way below line-in levels.
You need a pre-amp of some sort between the microphone & the Mac...

About halfway down the page is an explanation of the issue.

Sorry but I still do not understand. Where is the explanation? And what can I do to record audio?

"There are a myriad of different signal levels one can encounter in analog audio, but there are three ranges one is most likely to deal with: Microphone level, -10dB line-level and +4 dB line level.

Microphone level is usually somewhere in the range of 40-60dB lower than line level, and those signals need to be amplified before going to tape, or a mixer channel, or digital converters"

Pre-amplifier

Get either iMic or a USB mic... I tried explaining this to a PC user and only got laughed at... Its for professionals... whereas a PC you would need a high end sound card for this.
