Audio devices
Your computer offers built-in stereo speakers. See the section entitled
“Audio” on page 25 for more information on these features. However,
in addition to the integrated devices, the two audio ports on the left
side of the unit enable you to connect external audio input and output
devices.
You can plug an external microphone into your computer's micro-
phone-in jack. This offers the convenience of greater freedom of move-
ment, as well as improved audio input quality.
Connect headphones to the headphone jack for private listening and
improved audio output quality.
