Apple LC 550 manual Using the built-in microphone, Adjusting the screen

Using the built-in microphone

Your Macintosh comes with a built-in microphone to record live sounds. The microphone is highly sensitive. Once you’ve turned it on (which you do with a sound-recording program), it can pick up sounds within a range of several feet. See your Macintosh User’s Guide for information on recording sound.
