Notes for Proper Use of a Microphone
Hold a microphone to have the top of its windscreen
1 to 2 inches away from your mouth.
To get the best pickup result, point the microphone
toward your mouth.
To ensure a clear vocal output, do not block the lower
part of the microphone windscreen. Blocking the lower
part of the microphone windscreen will disturb the
proper voice reproduction with an unclear bass which
tends to cause the feedback (howling) results.
