Connecting and using a microphone
You can use the Apple PlainTalk Microphone that comes with some Macintosh computers (or
a compatible line-level microphone) to give spoken commands to your Macintosh and to
record your voice or other sounds. (The illustration of your computer in Chapter 1 shows
the Apple PlainTalk microphone.)
Note: Do not use the Apple Omni microphone (the round microphone supplied with some
older Macintosh models) or the attenuated RCA adapter provided with some Macintosh computers.
If your monitor has a built-in microphone that you want to use, see the information that
came with the monitor to connect the microphone.
To connect and position an external microphone, follow these steps:
1 Shut down the computer and plug the microphone’s connector into the sound input port
(≈) on the back of the computer.
2 Place an Apple PlainTalk Microphone at the top center of the monitor, so that the
microphone’s Apple (K) icon faces you.
If you’re using a different microphone, position it according to these guidelines:
m The microphone should be between 1 and 3 feet away from you.
m The microphone should be directly in front of you to minimize the effect of background noises.
3 Tu rn on the computer.
4 Open the Monitors & Sound control panel, click the Sound button, and make sure that the
microphone is the selected sound input source.
