Conference Microphone

🎤 1. No sound / microphone not recognized by the computer?

Check connections:
- Ensure USB/3.5mm plug is securely inserted; try a different port
System settings:
- Windows: Right-click volume icon → Sound settings → Select microphone as input
- Mac: System Preferences → Sound → Input
App permissions:
- Make sure meeting apps (Zoom, Teams, etc.) have microphone access permission

🔊 2. Why is the sound intermittent or noisy?

- Environmental interference: Turn off fans/AC or other noise sources
- Cable issue: Use a shielded anti-interference cable (especially for 3.5mm input)
- Driver issue: Update sound card driver (download latest from official site)

📢 3. How to reduce echo and feedback?

Physical adjustments:
- Keep microphone away from speakers (to avoid loopback)
- Use a directional microphone (e.g., cardioid)
Software noise reduction:
- Enable “Noise Suppression” in Teams/Zoom
- Use RTX Voice (NVIDIA GPU noise cancellation tool)

🗣 4. Why can’t others hear me clearly in remote meetings?

- Keep microphone 15–30 cm from your mouth (optimal pickup range)
- Enable gain adjustment (via software or microphone hardware button)
- Speak directly into the microphone (directional mics require facing the source)
