I'm trying to get ventrilo to talk to my friends but wow... this expensive machine doesn't even have a mic jack??
 
There is a Logitech USB mic that works well and is cheap (like $10 or so).

I'll gladly take your Mac Pro if you don't want it... :)
 
Either get an iMic from Griffin or buy a USB mic. The audio in is a line-in and requires a pre-amped or powered line-in.

It's great to hook up your stereo to your Mac Pro to record music from a casette.

This is an old thread but I can get the mic to work as well. I have a regular headset (earphones and mic) with two RCA plugs that I normally just plug in to the mic and headphone jacks on my PC's. Will this work on the Mac Pro or do I need a different type of mic? Powered speakers work fine (as do headphones)

Thanks
 
It's not a mic plug, it's a line in. You need a powered mic.

No you don't. The only types of microphone in the world that need power to run are Condensers and Ribbons. Even then they are only using dc voltage to piggy back the audio signal down the line.

Edit: To clarify between a line in and a mic in. Mic in's almost always use a 3 pin xlr balanced connector and an cable running at -4dBV. A line in, such as an input for a guitar or any household consumer audio equipment runs on 2 pin jacks and cables, and run at +10 dBV.

However using a mic in that input isn't ideal at all. The voltage will be so low from a dynamic mic (one that most consumers use and self generates an electrical signal using a moving iron bar surrounded by copper coils) that in order to get an audible signal you will have to boost the input so much it will be ridden with noise and possibly distortion.
 
wait for new cinema displays! ****kkkk:mad: a lot time with no cinemas I want news with isight!:D

A line in WON'T work for using a mic. We know its similar. Yes you could get some signal but it will be useless for the real world. So yes you need to get a griffin imic or USB mic etc.
