Connecting sound output devices
Your computer has a built-in microphone to the lower right of the display. For information on using the microphone to record sounds, see the “Sound” topic of Macintosh Guide, available in the Guide (h) menu.


Microphone
The Macintosh PowerBook also has a stereo sound output port (marked with the icon -) to which you can connect externally powered speakers, an amplifier, headphones, or other audio output devices. The sound output port accepts a standard stereo miniplug, like that used to attach headphones to a portable tape player.
