Microphone Basics Helper

Understand common mic types, proper handling, feedback prevention, and quick troubleshooting for church services.

Microphones seem simple, but small details like distance, direction, batteries, and mute buttons can change everything. Start with the basics.

Common Microphone Types

Handheld wired mic

Plugs into a cable. Simple and reliable. Common for pastors, singers, and speakers.

Wireless handheld mic

Uses a transmitter and receiver. Needs batteries. More freedom of movement.

Lavalier/lapel mic

Clips to clothing near the collar. Small and discreet. Used by teachers and preachers.

Headset mic

Worn on the head. Stays in position during movement. Great for worship leaders.

Podium/gooseneck mic

Mounted on a stand or lectern. Stays in one position. Reads from a set distance.

Instrument mic

Designed to capture sound from instruments (drums, guitar amps, piano). Not meant for vocals.

Basic Microphone Handling

Hold near mouth

4–8 inches is typical. Do not hold at waist or chin level — it will sound distant or muffled.

Do not cover the grille

Holding your hand over the top of the mic can cause feedback and muffled sound.

Do not point mic at speakers

Pointing the mic at a speaker causes feedback. Keep the mic away from the speaker system.

Mute when not in use

Many wireless mics have a mute switch. Use it between speakers or songs when appropriate.

Check batteries before service

Wireless mics should have fresh batteries before every service. Do not trust a low battery.

Handle gently

Dropping or knocking a mic can damage the capsule. Treat equipment with care.

Understanding Feedback

Feedback is that loud squealing or ringing sound. It happens when the microphone picks up sound from the speakers and amplifies it in a loop.

•Lower the channel volume or main output slowly until feedback stops

•Move the microphone away from the direction of the speakers

•Avoid cupping the microphone (holding over the top)

•Keep an appropriate distance — too close to a speaker always risks feedback

•If feedback persists, the gain may be too high — reduce it slightly
