Computer Sound Card Color Codes

Thursday, April 22, 2010

Sound Cards in computers have different color codes for each input/output peripherals like Microphones, Headphones, Speakers, etc.. Most sound cards have uniform or standard color coding for each connectors. Sometimes it may vary depending on the manufacturer. So better consult the manual if you have unstandard color codes.

The common three colors at the back of your tower for sound card is Pink, Lime Green and Light Blue. But new additional jacks may be present on newer sound cards for rear and mid surround speakers.

Sound Card color codes with each associated description:

PINK - Microphone

LIME GREEN - Line-out, Front Speakers, Headphones

LIGHT BLUE - Stereo Line-in

ORANGE - Subwoofer and center out

BLACK - Rear Surround Speakers for 5.1 and 7.1 systems

GRAY - Middle Surround Speakers for 7.1 systems

GOLD - Midi / Game port (Joystick)

Note: The number of jack connectors you'll find on your soundcard will depend on how many audio channels it has:

* Stereo cards with just two audio channels will have only the green (output), blue input) and pink (microphone) jacks.

* A few sound cards with 8 (7.1) audio channels do not provide the gray (Middle Surround Speakers) connector. If your computer is equipped with this type of card and you want to use all the 8 channels you will need to connect your motherboard to a 7.1 home theater system using the SPDIF digital connector.

* Some motherboards with 4 or 6 channels don't have the black (Rear Surround) and orange (Subwoofer and Center) jacks. These cards will use the blue jack for both line in and rear surround speakers out, and the pink jack for both mic input and subwoofer/center out. Therefore, whenever you want to use any of these jacks for a different function, you will have to manually remove one jack connector and plug in another.
