How to Use a Lavalier Microphone When Shooting a Video

　　Many of my friends have Lavalier microphone in their hands and, as such, they often have a headache for Lavalier. Headache is mainly concentrated in the use of Lavalier microphone, the volume can not push up, push a little bigger, it is prone to howling. If you use the equalizer pull whistling, pulled not howling, and the sound of the microphone can not listen, thin and loose hair again.

　　Why is there such a situation? First of all, microphone whistling is an important reason, that is, the microphone can receive the sound emitted by the speaker. As long as the microphone can receive the sound emitted by the speakers, the path of positive feedback is established. As long as there is a positive feedback path, as long as the sound emitted by the loudspeaker to a certain extent, positive feedback that is howling will happen.

　　See here, many of my friends will ask: Why Lavalier microphone on the stage, behind the speaker, but also did not open the audiophile, or prone to howling?

　　First of all, the sound emitted by the speakers has high, medium and low frequency, the higher the frequency of sound transmission direction, while the lower the frequency of sound direction is poor, less than 250 Hz sound can basically be said that there is no transmission of the direction. Then, although the microphone is on the stage behind the speaker, the sound of the lower frequency emitted by the speaker still radiates to the stage and is received by the microphone.

　　So why is the Lavalier microphone whizzing more easily than the moving microphone? Have you ever noticed the directivity of your Lavalier microphone while using the Lavalier microphone? I believe many people have not noticed this problem. Lavalier microphone mic orientation is also sub-omnidirectional, heart-shaped, super heart-shaped type, if you buy the hand is omnidirectional microphone, then can only say that this is a tragedy! Howling will always be with you! Are you using a cardioid microphone? Have you noticed the corresponding direction of the microphone head when wearing the microphone for the actor? Did you point the actor's mouth? Or did you give the microphone to the actor himself? Under the circumstances, if worn in the wrong direction, then the same, howling is still inevitable.
