1. Do not use it on the mesh head of Best uhf ktv wireless microphone AY-URX7Ⅱ

Some performers use the way of holding the mesh head of the microphone with their palms. This is a bad posture that seriously damages the sound quality and directivity of the microphone. Using a microphone in this posture, even if the most expensive microphone is used, it will make the original factory excellent. characteristic, and thus loses pitch. The result of holding the mesh head with the palm of the hand is equivalent to isolating the sound circuit around the sound head air chamber or changing the resonant frequency of the air chamber, which will lead to serious deterioration of the front frequency response characteristics and directional characteristics of the microphone.

2. Make good use of the distance between the Best uhf ktv wireless microphone AY-URX7Ⅱ and the mouth

Use the directional Best uhf ktv wireless microphone AY-URX7Ⅱ to sing, pay attention to the posture of holding the Best uhf ktv wireless microphone AY-URX7Ⅱ, because of the distance between the microphone and the mouth, the sensitivity and sound quality will have a considerable change, especially because the microphone The sensitivity of the microphone is inversely proportional to the square of the distance from the mouth, so performers with insufficient throat strength should not hold the microphone too far from the mouth, which will easily lead to feedback sound; for singers with loud throats, it is not necessary to hold the microphone too close to the mouth , which can easily lead to transient saturation distortion of the amplifier.
