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