Types of audio ports
Headphone port — Connect headphones, powered
speaker, or sound system.
Microphone port — Connect external microphone for
voice or sound input.
Line-in port — Connect a recording/playback device such
as a cassette player, CD player, or VCR.
Line-out port — Connect headphones or speakers that
have an integrated amplifier.
Rear-surround out port — Connect multi‑channel
capable speakers.
Center/LFE surround out — Connect a single subwoofer.
NOTE: The Low Frequency Effects (LFE) audio channel,
found in digital surround sound audio schemes, carries
only frequency information (80 Hz and below). The LFE
channel drives a subwoofer to provide extremely low
bass extension. Systems not using subwoofers can shunt
the LFE information to the main speakers in the surround
sound setup.
