How to choose a professional K-song microphone? Distinguish between monitoring human voice and ordinary entertainment microphone

Many people can't tell the difference between ordinary household microphones and professional voice monitors. When they buy them, they find that the sound quality is thin, the treble is stuffy, the bass is turbid, and singing is very difficult.
Ordinary entertainment microphones only do simple pickup and have a wide range of reception, so it is easy to include environmental noise, air conditioning wind and speaker echo together, so howling often occurs in private rooms. If you want to speak easily, the core depends on the radio structure.
In-ear voice monitoring microphone has a built-in directional pickup head, which only captures the voice in front of the mouth, and the lateral environmental noise will be automatically filtered. Even if the volume of the speaker is very loud, it is not easy to produce self-excited howling. There is no need to deliberately suppress the voice when singing high notes. The voice is clean and transparent, and the bass is full and solid.
On the wireless transmission level, the frequency of ordinary U-segment microphones is fixed. Once the frequencies of microphones in nearby boxes overlap, crosstalk and signal jamming will occur. High-quality true diversity wireless microphone has two channels of signal reception, and the two antennas of the receiver work independently. One signal is blocked and the other one takes over seamlessly at once. Even if you walk around the room with a microphone in your hand and go to the corner, behind the door and other weak signal areas, the sound will not get stuck and disconnected.
Home KTV, audio-visual room and small concert venue are the easiest to ignore the power supply problem. Unstable voltage will cause sound quality distortion and intermittent sound breaking. The high-quality receiver is equipped with a voltage stabilizing circuit, which can still keep the signal stable when the voltage fluctuates and prevent the loss of sound quality caused by the voltage.
Many novices blindly pursue loud volume and ignore the degree of vocal restoration. A good microphone can restore delicate breath sound, hum softly and clearly, roar high notes without breaking sound, and the wet and dry sound effects are balanced naturally, so there is no need to adjust the power amplifier parameters frequently.
Summary:
Family K songs give priority to directional pickup+dual-antenna true diversity wireless model, which can not only prevent howling and environmental interference, but also ensure long-distance mobile use without interruption, which is more stable for long-term use
