Connecting sound input and output devices

Your computer has a built-in microphone. In addition, you can connect a PlainTalk microphone to the external sound input port. (You can also connect a standard line-level input microphone, although it is not suitable for speech recognition.)

For information on using the microphone to record sounds, see the “Sound” topic area of Mac OS Guide, available in the Guide (h) menu.

Microphone

Your Macintosh PowerBook also has a stereo sound input port (marked with the √ icon) for connecting external sound input devices that provide line- level output. You cannot use the internal microphone and an external sound input device, such as a PlainTalk microphone, at the same time. For instructions on selecting a sound device, see the “Sound” topic area of Mac OS Guide, available in the Guide (h) menu.
