Apple 640 manual Connecting external stereo speakers

Connecting external stereo speakers

You can take advantage of your computer’s stereo sound output by attaching externally powered (amplified) speakers. (Only externally powered speakers will work with your Macintosh.)

1Assemble the speakers and the cable you need.

You need a cable with stereo miniplugs at each end to connect one or both speakers to the computer. (Some speakers require a dual-plug adapter. Others, like those shown here, accept a single stereo miniplug and are joined by standard speaker wires.)

The following illustration shows the equipment configuration and the connections for a computer sound system.
