a microphone with a 3.5-mm plug.

sound will be recorded.
■ If you connect a monaural (single-channel) microphone,
left-channel sound will record on both channels.
■ If you connect a dynamic microphone, the recommended
sensitivity may not be achieved.
■ When an external microphone is connected to the notebook,
the notebook internal microphone is disabled.
Using the Audio-Out (Headphone) Jack
Å
WARNING: To reduce the risk of personal injury, adjust the volume
before putting on headphones or a headset.
Ä
CAUTION: To prevent possible damage to an external device,
do not plug a single sound channel (monaural) connector into the
headphone jack.
The headphone jack is also used to connect the audio function
of an audio/video device such as a television or VCR.
When connecting a device to the headphone jack:
■ Use only a 3.5-mm stereo plug.
■ For best sound quality, use 24-ohm to 32-ohm headphones.
