4 Attach the cable to the audio equipment and to the appropriate sound port on the
Macintosh.
To hear or record incoming sound on the computer, connect the audio
equipment to the sound input port (X).
To record the sound produced by the computer or play that sound through
externally powered (amplified) speakers, connect the audio equipment to the
sound output port (-).
5 Turn on the computer and the audio equipment.
You’re now ready to begin listening to and working with sound. For more
information on working with sound, see the “Sound” topic of Macintosh
Guide, available in the Guide (h) menu.
Connecting and positioning a microphone
With appropriate software, you can use a microphone to give spoken
commands to your Macintosh and to record your voice or other sounds.
You need the Apple PlainTalk Microphone (or a compatible microphone)
to use speech-recognition technology with the Macintosh.
Some models of the Macintosh come with the Apple PlainTalk Microphone.
You can obtain the microphone from an Apple-authorized dealer. (You can’t
use the round microphone supplied with some other Macintosh models.)
Note: The Apple AudioVision 14 Display has the Apple PlainTalk
Microphone built in.
