Your 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 at the same time. For instructions on selecting a sound device in the Sound control panel, see the “Sound” topic of Macintosh Guide, available in the Guide (h) menu.
WARNING Do not plug a sound output device (such as a pair of headphones) into the sound input port. Doing so may damage your audio equipment.
The PowerBook also has a stereo sound output port (marked with the icon -) to which you can connect 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.
