Apple Macintosh Performa 6360 Series - Manual (Page 45)

Connecting external stereo speakers
You can take advantage of your computer’s stereo sound output by attaching
externally powered (amplified) speakers.
1 Assemble the speakers and the cable you need.
You need a cable with a stereo miniplug at one end to connect one or both
speakers to the computer.
Some speakers require a dual-plug adapter, which has two plugs on its end, to
plug into Audio In ports on both speakers. Others, like those shown below,
accept a single stereo miniplug and are joined by standard speaker wires. See
the documentation that came with your speakers for more information.
The following illustration shows the equipment configuration and the
connections for a computer sound system.
