Using the audio-in (microphone) jack
The computer is equipped with a stereo (dual-channel) microphone jack that supports an optional stereo
array or monaural microphone. Using sound recording software with external microphones allows for
stereo recordings.
When connecting a microphone to the microphone jack, use a microphone with a 3.5-mm plug.
Using the audio-out (headphone) jack
WARNING! To reduce the risk of personal injury, adjust the volume before putting on headphones,
