Ports and connectors
Audio
Audio connectors allow you to connect speakers, headphones, microphones, sound systems, amplifiers, or TVs audio output.
NOTE: Your computer may not support all the audio ports. For information on the ports available on your computer or tablet,
see the Quick Start Guide shipped with your computer or see the Setup and Specifications at www.dell.com/support.
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.
RCA S/PDIF port—Transmits digital audio without the need of
analog audio conversion.
