Audio Connectors
Audio connectors allow you to connect to amplifiers, speakers, headphones, microphones, sound systems, or TVs for digital audio output.
Types of audio connectors
Microphone connector — Connect a personal computer microphone for voice or sound input.
Line-in connector — Connect a recording/playback device such as a cassette player, CD player, or VCR.
Line-out connector — Connect headphones or speakers with integrated amplifiers.
Rear surround out — Connect multichannel-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 connector — Connect additional speakers.
RCA S/PDIF connector — Transmit digital audio without the need of analog audio conversion.
Optical S/PDIF connector — Transmit digital audio without the need of analog audio conversion.
5.1 Audio
5.1 refers to the number of audio channels in most surround-sound configurations. A 5.1 audio system uses five main audio channels (front left, front right,
center, left surround, and right surround) and one low-frequency audio channel.
7.1 Audio
7.1 refers to the number of audio channels in high-end surround-sound configurations. A 7.1 audio system uses two additional speakers (rear left and rear
right) in combination with the 5.1 audio system.
NOTE: 5.1 or 7.1 audio may not be supported on all computers.
NOTE: On computers with a discrete sound card, connect the speakers to the connectors on the card.
