The 4237B 3D sound system contains two controls—a space control and a center
control—for adjusting the spatial effect of sound played through speakers connected
to your computer. Turning up the level of the space control increases the amount of
corrected directional information, restores the proper localization of the original
sounds, and expands the width of the overall sound stage. Turning down the level of
the space control decreases these effects. Always adjust the space control before
adjusting the center control. Turning up the center control emphasizes centered
sounds (typically vocals, solo instruments, bass, and kick drums in a musical record-
ing) so that their intensity appears increased and they are brought into the center of
the room.
To adjust the space and center controls, follow these steps:
1. Start the Windows 95, Windows 98, or Windows NT operating system.
2. Click right on the blue circle icon in the lower-right corner of the taskbar.
3. Click the Enabled check box in the control panel that appears.
4. Slide the Space and Center control slide switches until you achieve the desired
effect.
