Connecting and Using Sound Input 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.) You can find
more information on using the microphone to record sounds in the online help, available in
the Help menu.
Note: When using an external microphone, set the volume to 50 percent and point the
microphone away from the PowerBook speakers. Pointing the microphone towards the
speakers with the volume set to maximum may result in feedback.
Because your PowerBook can receive sounds from a variety of different sources, such as the
internal microphone, expansion bay module, or zoomed video card, you need to select a
sound input source.
m Click the Sound Source icon in the Control Strip and choose an input source from the
menu that appears.
