On some motherboards, the audio-in header is named as AUX or line-in. For connecting to AUX 1x4 pins header, please read notes at the bottom of this page.		AUDIO-IN PORT INTERNAL SPECIFICATIONS PRODUCT NAME FRONTX Audio-In Port Internal PRODUCT CODE CPX092-2 BAY USAGE Half of small bay CONNECTORS Stereo audio 1/8 inch (3.5 mm) female 1x3 header connector female CABLE Stereo audio cable (UL 2835) Length - 2.5 feet (762 mm) WIRE ASSIGNMENTS Black: Line-In Left / Audio-In L / L-In L / AUX L Black: Ground / GND / Audio GND / AU GND Red: Line-In Right / Audio-In R / L-In R / AUX R The GND (ground) wire is fatter and can be easily recognized. HEADER CONNECTION GUIDES Diagram 1: On most motherboards, the pinouts of audio ports are grouped together. You need to find out which 3 pins are assigned as L-In L, L-In R and GND. Diagram 2: Simply plug the connector onto the header/pin-out, in such that; black wire is connected to L-In L pin, red wire to L-In R pin and the ground wire to GND pin. If the 3 active pins are not aligned in one same row (refer to diagram above), you need to change the header connector, and rearrange the wires to match with the pin assignments. NC pin (no connection - empty) is not a GND pin. Do not connect the ground wire to NC pin. AUX 1X4 PINS HEADER On some motherboards, the audio-in header is by itself, i.e. not grouping with the headphone and microphone pinouts. This audio-in header is named as AUX, and consists of 4 pins arranged in 1 row. To connect to the AUX header, you can use the 1x4 header connector which can be purchased at our webstore. Please note that there are 2 GND pins in this header, just connect the ground wire to either one of the 2 GND pins, and leave the other GND pin unconnected.
