Microphone Types
Lapel Microphone (Lavalier)
- A small clip-on microphone typically worn on the collar or lapel.
- Wireless, connects via bodypack transmitter.
- Best for lectures or presentations that involve walking around.
- Clip the mic around six inches below the chin. Avoid brushing against clothing or jewelry.
Handheld Microphone
- A microphone held in the hand or placed in a mic stand.
- Can be wired or wireless depending on the room.
- Best for Q&A sessions, panels, or when passing the mic around.
- Hold the mic close to the mouth and speak directly into the top.
Gooseneck Microphone
- A long, flexible microphone mounted to the lectern or podium.
- Usually hardwired directly into the AV system.
- Ideal for stationary speaking positions such as at a podium.
- Bend the neck so the mic is six to eight inches from the mouth.
Ceiling Microphone
- Microphones installed in the ceiling to passively capture room audio.
- Usually used for lecture capture or video conferencing.
- No user setup is required.
- May not clearly pick up soft voices or distant students. Best used in smaller rooms or with good acoustics.
Microphone Use Best Practices
- Always test the microphone before class using the AV control panel or sound check tool.
- If using a wireless mic, confirm it is turned on and fully charged or has fresh batteries.
- Speak clearly into the microphone and maintain a consistent distance from your mouth.
- Avoid placing the mic near speakers or monitors to prevent feedback.
- Do not put lapel or handheld mics in bags or pockets when not in use.
- If using multiple microphones, make sure the system supports simultaneous use or turn off unused mics to avoid interference.
Troubleshooting Steps
- If the microphone is not working:
- Check that it is selected and unmuted on the AV control panel.
- Verify that the mic is turned on and properly connected (or paired if wireless).
- Inspect for battery issues or range limitations.
- Make sure you are using the correct input channel for the mic in the room.
- Try switching to a backup mic if available.
