How to Choose and Set Up an External Microphone Instead of Built-in?

Introduction

Built-in microphones in laptops often deliver mediocre quality — quiet sound, fan noise, echo. The solution is simple: connect an external microphone. In this article, we'll explain how to choose, connect, and properly configure it in Windows so your voice sounds clear and without distortion.


Quick Solution

  1. Connect the external microphone.
    USB — simply plug it into a port; 3.5mm — connect to the jack with a 🎙️ icon.
  2. Set it as default.
    Control Panel → Sound → Recording → Right-click on device → "Set as Default Device".
  3. Check volume and signal level.
    Settings → System → Sound → Input → Test microphone.
  4. Test on DoCam.io before a call or stream.

2. Connecting the Microphone

Connect the microphone and wait for Windows to install the driver. For USB devices, installation happens automatically. If Windows doesn't recognize the microphone — restart the computer or try a different port.

3. Setting Default Device

1️⃣ Press Win + R → type mmsys.cpl.
2️⃣ Open the Recording tab.
3️⃣ Find the external microphone (e.g., "USB Mic" or "Blue Yeti").
4️⃣ Right-click → Set as Default Device.

4. Adjusting Levels

1️⃣ Select the device → Properties → Levels.
2️⃣ Set volume to 90–100% and, if necessary, enable "Microphone Boost".


5. Checking in Applications

  • Zoom: Settings → Audio → select your microphone from the list.
  • Discord: User Settings → Voice & Video → select device manually.
  • OBS: Add source "Audio Input Capture" → select external microphone.

6. Driver Check

If the microphone doesn't work, open Device Manager → Audio inputs and outputs and ensure the device appears without errors.

7. Physical Setup Tips

  • Position the microphone 15–20 cm from your mouth.
  • Use a pop filter or windscreen for smoother sound.
  • Don't aim the microphone directly at the keyboard or fan.

Tips

  • Disable the built-in microphone to avoid dual signal.
  • Regularly check volume on DoCam.io.
  • If using XLR — adjust gain level on the audio interface.
  • For USB microphones, no external drivers needed — just select the device.

Conclusion

Done! Now the external microphone fully replaces the built-in one and provides clear, rich sound. Before video calls and streams, don't forget to check the signal level — it's the key to making a good impression with your content.
