Recommendations
We recommend that you follow the rules below:
Hold a microphone in its middle. If you hold it at its lower part, you interfere with its built-in antennas.
Keep the microphone in the almost horizontal, slightly downward position.
Direct the sound to the center of the microphone membrane.
Do not move the microphone toward the loudspeakers.
The best distance between the microphone and your lips is 2-5 cm.
Bring the microphone closer to your lips several seconds before you start singing to ensure the first phrase is
complete.
Mute your microphone when it is not in use.
