Question

What's a little orange plug that says SPDIF beside it do?

Answer 1

S/PDIF



The name stands for Sony/Philips Digital Interconnect Format (more commonly known as Sony Philips Digital Interface),



A digital audio interconnect used in consumer audio equipment.



EDIT:



SPDIF is used for transporting stereo digital audio signals on PC audio cards, CD players, DVD players, car audio systems, and other systems which transmit or receive stereo digital audio.



The main advantage of SPDIF Digital transference (.vs original analog transmissions), is noise immunity.



For example, if a CD-ROM drive has poor quality D/A (digital-analog) converter; it can generate all kinds of undesirable hiss, static and other unwanted ambient noise.



Also, if the signal between the CD-ROM drive and the sound card is transferred via analog format; the connection cable used can often times act as an antenna of sorts.



It can actually pick up unwanted “stray” noise, which is generated from the typically-occurring internal computer chassis electro-magnetic interference.



Therefore, if your sound card has a SPDIF input and your CD-ROM drive has a SPDIF output- Instead of using a shaky analog connection; opt for a crisp, clean SPDIF connection- you won’t be disappointed.

Answer 2

it is analog AUDIO.. nothing more

Answer 3

Holy **** have you ever heard of google? You typed over 100 keystrokes + clicking to ask that when you could just type SPDIF (5 letters) into google press enter (1 button) and then you don't even have to click anything! It says what it is on google, you don't even need to click on a site.



SPDIF is digital audio, I assume that is it coming out of your computer. A SPDIF input on a laptop doesn't make much sense to me.



Evil taco guy is wrong, analog audio would be the red/white wires.
