Wireless microphone is a microphone that needs to be used in many occasions, and it also brings great convenience to stage performances, but many people are not very good at using wireless microphones. The following editor will introduce how to use wireless microphones.
How to use wireless microphone
First, insert the receiver cable into the output hole on the receiver, the same as the microphone connection. Connect the other end of the cable to the audio port of the amplifier microphone. Then plug the power cord into the wireless receiver, and plug the other end into the power source. When installing the battery of the wireless microphone, pay attention to the positive and negative poles. Turn on the power of the receiver, and then turn on the power of the wireless microphone. If the connection is correct, the signal light will show green. The signal and connection methods of wireless microphones are both troublesome.
1. Don't use it on the net head of the wireless microphone
Some performers use the method of holding the microphone mesh head in their palms. This is a bad posture that seriously damages the sound quality and directivity of the microphone. This posture uses the microphone, even if the most expensive microphone is used, it will make the original factory have the best Characteristics, and thus lose the tone sandhi. The result of holding the mesh head with the palm of the hand is equivalent to isolating the sound circuit around the capsule air chamber or changing the resonance frequency of the air chamber, which will cause the microphone's frontal frequency response characteristics and directivity characteristics to be severely degraded.
2. Make good use of the distance between the wireless microphone and the mouth
When using a directional wireless microphone to sing, pay attention to the posture of the wireless microphone. Because the distance between the microphone and the mouth, the sensitivity and sound quality will change significantly, especially because the sensitivity of the microphone is inversely proportional to the square of the distance between the mouth. Performers with insufficient throat power should not hold the microphone too far away from the mouth, which will easily lead to feedback sound; for loud throat singers, do not need to hold the microphone too close to the mouth, which will easily lead to over-saturation distortion of the amplifier.
3. Avoid using the wireless microphone facing the speaker
The posture of the wireless microphone should be vertical or horizontal, and the angle of the speaker should be more than 90 degrees, which can reduce the occurrence of feedback sound. If you don’t understand the directivity of your own microphone and use it in front of the speaker, it is easy to cause loud feedback. Because the microphone and the speaker face each other at the most taboo angle, under such an angle, no matter what kind of wireless microphone, it is easy to produce screaming feedback sound.
