The red one is the MIC, which is connected to the microphone (the headset with a microphone has a red line that is also plugged into this port)
The yellow one is LINE IN, which is the audio input, which can be connected to some devices that input sound (that is, the sound is transmitted through the data cable), such as the audio cable of the TV card (so that the sound of the TV can be received).
Add a coaxial output interface for the optical drive
Some friends who have an external DAC often look for cheap digital audio sources on PCs. Unfortunately, there are not many sound cards with good digital output quality. CD-ROM is a good digital audio source, but it is not convenient to connect to DAC. The best The solution is to add a coaxial output to the optical drive. Such a transformation can make the optical drive separate from the PC and become a pure turntable.
Find a CD-ROM drive with a play button. The arrow points to the play button. Many older models of CD-ROM drives do not have this button. There must be a digital output on the back, and the 2pin socket is a digital output socket. Find a digital CD cable (the LED light connection of the chassis is also ok). Cut one of the ends, and it is recommended to wrap it with a heat-shrinkable tube or twisted tape at a later position of the thread to prevent the thread from unraveling. After the wire is stripped, it must be tightened, preferably over tin, to prevent the wire from spreading and causing a short circuit.
Prepare an RCA socket, preferably with a single head. We choose the red one for output. On the back of the socket, the red, green and blue arrows correspond to the red plug, white plug and ground wire respectively. We connect the two wires of the digital CD cable to the pins pointed by the red and blue arrows. This connection method is very simple and rough. If you have the conditions, you might as well use a universal board to make it more beautiful. We use heat-shrinkable tubing for insulation. When making this wire by hand, please be careful to prevent short circuits. Connect the optical drive to the 2Pin end, and connect the coaxial digital signal cable to the other end. If there is no signal output, it may be that the 2 pin is plugged in the wrong direction. If there is still no sound, then the digital output of this optical drive may be fake.
Turn off the computer, use the DIYEden SVDAC01 external DAC as the decoder, use an AT power supply as the power to drive the optical drive, and cut off the power supply fan, everything is as desired, the speaker emits wonderful music, no SRC interference, no electromagnetic interference in the chassis Without fan noise interference, a good system was built.
