Apple Macintosh 6500 - Manual (Page 49)

Using the built-in subwoofer
Your computer comes with a built-in speaker that produces full-range,
monophonic sound. When you attach external speakers, the computer’s built-
in speaker changes mode and functions as a subwoofer, adding bass sound to
augment the speakers’ stereo sound.
You adjust your computer’s volume with the volume controls on the front of
the computer or with the Monitors & Sound control panel in the computer’s
software. (For more information, see “Adjusting Volume and Sound” earlier in
this chapter.) However, when you attach external speakers (or if your monitor
has built-in speakers), you adjust the subwoofer volume independently of the
speaker volume. You do this by adjusting the subwoofer balance control (Ï)
on the back of the computer. (The subwoofer balance control affects the
subwoofer volume only when external speakers are attached.)
Connecting audio equipment
To play or record sound with your Macintosh, you can attach a microphone,
an amplifier, a tape recorder, or a pair of speakers.
You need a cable with one of the 3.5 mm audio connectors shown below to
connect a microphone or other equipment to your computer’s sound input
port (≈). You need a cable with a stereo miniplug to connect speakers or other
equipment to the sound output port (-).
