Connecting headphones
You connect headphones to the headphone jack (f) on the front of the
computer or to your monitor if it has a headphone jack.
If you use the headphone jack on your monitor: When you plug headphones
into the headphone jack on your monitor (if your monitor has one), sound
comes through your headphones but, depending on the type of monitor you
have, it may also continue to come out of the subwoofer. To stop this,
plug your headphones into the headphone jack (f) on the front of the
computer, not the headphone jack on the monitor. However, if you prefer to
plug the headphones into the monitor, silence the subwoofer by manually
turning down the subwoofer balance control (Ï) on the back of the computer
all the way. Also, when you’re finished using the headphones, remember to
turn it back up.
Note: You may also want to disable 3D Surround Sound in the
Monitors & Sound control panel if you are listening through headphones.
3D Surround Sound does not always work through headphones. To disable
3D Surround Sound, open the Monitors & Sound control panel in the Control
Panels folder in the Apple (K)menu and click the checkbox to remove the
checkmark next to “Enabled.”
For more information on listening with headphones, see the “Sound” topic of
Macintosh Guide, available in the Guide (h)menu.
