Do you have these precautions when using the microphone?
matters needing attention
(1) do not hold the net head of the microphone with your hand.
The receiving part of all microphones has a certain directivity. If you hold the mesh cover with your hand, the directivity and frequency response of the microphone will be changed. Due to the aggregation effect of the palm, there will be backflow and howling.
(2) do not hold the antenna transmitting part of the microphone.
In general, the transmitting circuit and antenna of a handheld microphone are located at the lower part of the microphone (far away from the microphone). When human hands touch the antenna, most of the radio frequency is lost because it can not enter the air, which reduces the application scale of the wireless system and affects the reception effect.
(3) keep the distance between the microphone and the mouth properly
When using a handheld wireless microphone, it is better to keep the distance between the microphone and the mouth at 5-10 cm. If the microphone is too close, it will cause proximity effect, and if it is too far away, the sound quality will be damaged. When using the Lavalier microphone, it is necessary to prevent the microphone from being too far away from the mouth, and try to be close to the mouth; when using the headband microphone, it is necessary to prevent the mouth from directly talking to the head of the barrel, so as to prevent the impact of the acoustic airflow Move both ends.
(4) prevent the microphone from pointing directly at the speaker.
If the microphone is directed directly at the speaker, the system will form a closed loop, and positive feedback (howling) will occur, which is necessary to prevent.
(5) prevent two wireless microphone transmitters against each other to avoid intermodulation interference.
(6) do not pat the sound-absorbing head of the microphone with force in order to avoid damaging the microphone head.

What is the general classification of microphones in a studio?
Microphones are generally classified according to the way they are converted. Here, we divide the microphone into dynamic microphone and condenser microphone according to the general classification of microphone in recording room. A microphone that produces an electrical signal from a conductor moving in a magnetic field. It is the vibration of the coil driven by the diaphragm, so that the coil in the magnetic field generates induced current. Features: firm structure, stable performance, durable

What is a u-segment microphone? What are the advantages of u-segment microphones?
U-Band wireless microphones indicate that they can accept U-Band microphones. U-Band wireless microphones generally refer to 30-3000mhz communication. U-Band wireless microphones are suitable for families or small conference rooms. The ability to receive signals is stronger than that of V-band wireless microphones. However, the number of wireless microphones should not exceed four to avoid affecting the signal acceptance ability. Precautions for equipment application: 1. Keep the U-section wirel
