matters needing attention
(1) do not hold the net head of the microphones with your hand.
The receiving part of all microphoness has a certain directivity. If you hold the mesh cover with your hand, the directivity and frequency response of the microphones 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 microphones.
In general, the transmitting circuit and antenna of a handheld microphones are located at the lower part of the microphones (far away from the microphones). 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 microphones and the mouth properly
When using a handheld wireless microphones, it is better to keep the distance between the microphones and the mouth at 5-10 cm. If the microphones 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 microphones, it is necessary to prevent the microphones from being too far away from the mouth, and try to be close to the mouth; when using the headband microphones, 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 microphones from pointing directly at the speaker.
If the microphones 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 microphones transmitters against each other to avoid intermodulation interference.
(6) do not pat the sound-absorbing head of the microphones with force in order to avoid damaging the microphones head.

What is the general classification of microphoness in a studio?
Microphoness are generally classified according to the way they are converted. Here, we divide the microphones into dynamic microphones and condenser microphones according to the general classification of microphones in recording room. A microphones 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

In addition to the use of a blowout preventer, what other ways to reduce noise?
With the rise of online karaoke and various channels of live broadcasting, more and more people like to record their own video and audio. At present, there are many kinds of microphoness. How to choose a suitable microphones has become a more troublesome job for some music lovers or anchors. When singing with a microphones, there is often a problem, which is to spray wheat. Since the 1970s, capacitor Macintosh has become the standard configuration of recording studio. It has high restoration height

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