Apple 6400 appendix Using the built-in subwoofer, Adjusting volume and sound

Using the built-in subwoofer

Your computer comes with a built-in speaker that produces full-range, monophonic sound. When you attach external speakers, this speaker changes mode and functions as a subwoofer, adding bass sound to augment the speakers’ stereo sound.

Follow these tips about your computer’s subwoofer:

mYou 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” later in this section.) 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.)

mIf your monitor has a headphone jack and you plug your headphones into it, the subwoofer sound might continue to come from the computer rather than through the headphones. To avoid this, plug the headphones into the jack on the front of the computer. If you prefer to keep the headphones plugged into your monitor, manually lower the subwoofer volume by turning the subwoofer balance control (Ï) counterclockwise. Remember to turn it back up again when you are finished using the headphones.

Adjusting volume and sound

There are several ways to adjust the volume on your computer:

mUse the volume controls on the front of the computer (marked with the - icon, above the power-on light).

mUse the volume controls on the front of your monitor if your monitor comes with built-in speakers.

mUse the volume control slider in the AppleCD Audio Player if you are playing an audio CD. The AppleCD Audio Player can be found in the Apple (K) menu.
