Audio connectors - NetVista / ThinkCentre

Your computer comes with an audio controller that supports Sound Blaster applications and is compatible with the Microsoft Windows Sound System. The audio controller provides you with the ability to record and play sound and music and to enjoy sound with multimedia applications. You can connect stereo speakers to the Line-Out connector to enjoy better sound quality.

Procedures for recording and playing back sound vary by operating system. Refer to your operating system documentation for information and instructions.

The audio connectors in your computer are 3.5 mm (1/8 inch) mini-jacks. A description of the connectors follows. Your computer might not have all connectors that are shown.
