Connecting a microphone
Your PowerBook has a sound input port to which you can connect
an external microphone. (Sound recording is described in the
chapter Adapting Your Computer to Your Own Use.)
1. Open the door covering the back panel of your
computer.
2. Plug the microphone into the sound input port on the
back panel. The sound input port has the icon X.
3. Decide where you want to place the microphone.
s 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.

Sound output devices
The PowerBook also has a 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.
