• Audio line-in connector
Used to receive audio signals from an external audio device, such as a stereo system. When you attach
an external audio device, a cable is connected between the audio line-out connector of the device
and the audio line-in connector of the computer.
• Audio line-out connector
Used to send audio signals from the computer to external devices, such as powered stereo speakers,
headphones, or multimedia keyboards. To attach a stereo system or other external recording device, a
cable is connected between the audio line-in connector of the device and the audio line-out connector
of the computer.
Note: If your computer has both an audio line-out connector and a headset connector or headphone
connector, always use the headset connector or headphone connector for earphones, headphones, or a
headset. However, a headphone connector does not support the microphone of a headset.
