[MV] Quick Microphone Question

[Chuck Rogers]

Dave:

You will ALWAYS need to use a USB adapter with a microphone unless  
you amplify the microphone's signal in some way before you plug it  
into your Mac. The reason for this is because Macintosh computers  
have LINE IN sound input ports, not MIC IN. LINE IN expects an  
amplified signal.

Macintosh computers have not been able to accept a Microphone  
straight in since the original Bondi Blue iMac. Older (much older)  
Macs had a unique "PlainTalk" sound input jack. They still couldn't  
use a normal microphone input, but if you had a special microphone  
with an elongated jack (that could reach the small power supply  
attached to the input jack) you wouldn't need an external amplifier  
(although you still needed to use a special microphone with the right  
type of elongated mini jack).
