The telephone and microphone headset (TMG) looks like ordinary headphones, but has a lateral movable element, at the end of which there is a microphone. It connects to the computer's sound card with two cables.
Instructions
Step 1
Check if the telephone / microphone headset is properly connected to the computer. On the sound card, the microphone jack is pink and the headphone jack is green. On a headset, the microphone plug can be pink or red, and the headphone plug can be black, green, or white. Sometimes they do not differ in color at all, but have stylized designations of a microphone and headphones. Finally, if they do not have any designations at all, they can be distinguished indirectly: for the microphone plug, the middle and common contacts are made as a whole or electrically connected to each other (the latter can be determined using an ohmmeter - the resistance should be close to zero). Do not plug the microphone plug into any of the output jacks on the card; this will short-circuit the right channel and risk damaging the amplifier.
Step 2
With the headset properly connected, turn on the computer, wait for the operating system to load, put on the headphones and speak into the microphone. If you hear your own voice, the connection is complete.
Step 3
If the headphones work, but the microphone does not, run the program that allows you to change the ratio between the levels of signals coming from different sources. In Windows, it is called, depending on the version, "Volume" or "Volume Control" and is located in the menu section "Standard" - "Entertainment". On Linux it is called "KMix", "Mixer", "Sound Mixer" or similar, and is found on most distributions under the "Multimedia" menu section.
Step 4
Find a virtual knob in the program that allows you to adjust the level of the signal coming from the microphone. If there is no such control, enter the program setting mode (the way to enter this mode depends on the OS) and turn on the display of this control. Next to it there is a box for a check mark, which in some versions of the program turns on the microphone, and in others turns it off. Make the microphone input switched on, then set the desired signal level from it with the slider. Do not make it too large, otherwise distortion will occur. After that, check again if the microphone is working.
Step 5
If you do not already have Audacity or a similar program on your computer that allows you to record sound files, install it. Record your own voice and then listen to the recording. The sound should be of high quality, almost without distortion.
