What is the blue connector near the audio output connector for?

Hello, I would like to know what this blue connector is for since the others are one for microphone and one for audio output.

Probably line in.

Line level audio is stereo.


Sound card color codes

The blue connector is Line In, i.e. from an audio device other than a microphone.


Hope this helps...

I work on a radio and the sound input is through the microphone connector and the output is through the output connector, and I put the input into the line input connector, configured it and the audio came in normally, but the voice doesn't come out, just the music comes out. I had to put the sound input into the line input because the microphone connector has bad contact. I wanted to know if I will have to use the microphone input again for the voice to come out along with the music, because as I said, the voice doesn't come out through the line input. Thanks to anyone who helps me.

Microphone input uses a much lower voltage than line input.

I think you would need to connect microphone to an amplifier and merge lineout from amp with other lineout with a two way connector?

Apparently you won't get the voice and music together through the line input. Only the music is coming out, but the voice is not coming out. I think I will have to buy a usb audio card.

the microphone input has poor contact, and this is where the music and voice come in, however, I removed the audio stream cable from the microphone input and placed it on the PC's line input, thinking that I had solved the problem, but the voice doesn't want to come out.

The only difference between microphone in and line in is the amount of electricity voltage. This video is about the differences between line out vs headphone out --- just different voltages.



Microphone input has a microphone pre-amp in the circuit (the yellow "mic boost" mic pre-amp). Line in (the green highlighted) doesn't have a "mic boost". Headphone out (or any line out that can be reconfigured to be headphone out) has a headphone amp in the circuit (the "I/O with A" in the circuit diagram). That's it. Nothing to do with the voice missing.



There is nothing different in the actual audio signal. So it has nothing to do with getting only music and not getting the voice. Or getting the voice and not the music.

There are only 3 different causes:
1) wrong cable i.e. you use a single channel TS audio cable and the voice is in the other channel but that is unlikely because all music have the singing in both channels. They never put music in the left channel and singing in the right channel.


2) you enable karaoke mode which strips out the voice so that you have only the background music for you to sing



3) you enable AI noise cancellation mode which strips out the background music and only the voice singing survive

Friend, here at the radio station where I work, we pull a cable with a p2 plug to the microphone input, and it is through this input that the songs play and it is through this that the announcer's voice comes out, that is, through this microphone input, we have music from the radio and the speaker's voice along the same cable and on the audio output, there is the audio output that goes to the soundboard and then to the fm transmitter. The audio input through the microphone connector is for online transmission, however, as the microphone input is failing, I took this cable that goes into the microphone connector and placed it in the line input and configured the audio options through the audio manager. audio and music radio programming plays normally, however, the announcer's voice does not come out, only songs, tracks... I would like to know if the microphone's voice comes out with the music via the line input or will I have to put the cable back in? on the microphone input to receive both the program music and the announcer's voice. Thanks for answering.

You would want to use a mixer or a microphone preamp, Microphones are low level signals and the line in won't pick them up.

Sound card or audio interface would be the best option these are something you should have anyway as radio station even a mixer. I am kind of dumbfounded on this tbh unless you are a hobbyist venture that is learning then that makes more sense.

Hello, thank you very much for your comment, we put an audio interface on the computer.

I wanted to resolve this doubt, I wanted to know if the line input would be used to capture the music from the program and the announcer's voice via the same p2 cable that comes out of the mixer, and from what I saw here it doesn't work, the voice doesn't come out, only the program music. Placing the same cable at the microphone input outputs the programming songs and the announcer's voice.
