Types of audio ports
Table 6. 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.
Side-surround sound port—Connect left/right speakers.
