Apple 6400 Personal Computer User Manual


 
Using a monitor with built-in speakers
If you have a monitor with built-in speakers, you can adjust the amount of
bass sound you hear coming from the computer’s subwoofer by adjusting the
subwoofer balance control (Ï) on the back of your computer.
Connecting audio equipment
To play or record sound with your Macintosh, you can attach a microphone,
amplifier, tape recorder, or a pair of speakers.
For instructions on connecting specific equipment, see the sections that
follow:
m “Connecting the Apple PlainTalk Microphone”
m “Connecting External Stereo Speakers”
m “Connecting Headphones”
The computer’s sound input port () accepts the 3.5-mm audio connectors
below. The sound output port (-) (where you might connect external
speakers) accepts only the stereo miniplug.
The stereo miniplug is found most often on stereo equipment (such as
external speakers). The extended miniplug, which is slightly longer and is
found on voice quality microphones (such as the Apple PlainTalk
Microphone), works only in your computer’s sound input port (). (Even
though it will fit into the sound output port, it won’t work there.) If your
equipment has a different type of connector than those shown here, you can
purchase an adapter at an electronics supply store.
