Apple Power Macintosh 9600 - Manual (Page 78)

Connecting audio equipment
Your Macintosh can play and record stereo sound from a variety of sources.
Your computer has sound input and output ports (also known as “jacks”) like
those found on most Macintosh models.
The sound input and output ports
Your Macintosh can handle stereo sound from a sound input device—also
called a sound source—such as a microphone, tape deck, or audio CD player.
(If you have an internal CD-ROM drive, it can also be used to play audio
CDs.) The term “sound input device” is used because the signal goes into your
computer for you to record or process in various ways.
Sound input devices can be attached to the sound input port, which is marked
with an icon of a microphone (≈).
Your computer comes with a built-in speaker, but you can attach an
additional sound output device, such as amplified speakers or headphones.
Sound output devices can be attached to the sound output port, which is
marked with an icon of headphones (f) or a speaker (-).
