Using Audio Devices
Your iMac comes with built-in stereo speakers, a headphone out/optical digital audio
out (f ) port, and an audio in/optical digital audio in (,) port.
Headphone Out/Optical Digital Audio Out Port
You can connect external powered speakers, headphones, 5.1 surround systems, and
other sound output devices to the headphone out/optical digital audio out (f ) port.
The headphone port is also a S/PDIF stereo 3.5 mini-phono jack. When you plug a pair
of headphones or another device into the mini-phono jack, sound comes through the
device instead of the iMac speakers. You can also play music through your home stereo
with iTunes and an AirPort Express Base Station.
