A good karaoke mic product has these considerations: the device can be used on its own and then shared on stage.
The conference microphone is divided into three frequency bands, FM band, and automatic amplitude limiting. The frequency of the FM band can be divided into four frequency bands according to requirements, one is high resolution, and the other is low distortion.
If there is a jumper in this section, there are still three frequency bands that need to be balanced. If there is some gap compression added, it is because they cannot be used simultaneously.
The sensitivity of the microphone can be used to measure whether the microphone is functioning properly. The microphone pickup frequency must refer to an error, otherwise it may cause more losses.
When using a microphone, it is also important to maintain consistency with the microphone. If the microphone volume is too high, it may cause a mismatch between the sound quality and other sound qualities.
Usually, at concerts, we may also encounter some weak factors, which are the low sensitivity of the microphone, so we rely on it. Some microphones may experience abnormal sound and generate noise interference. Therefore, we believe that the sensitivity of the microphone must be correct.
In addition to the high sensitivity of the microphone, the audience on site can also choose some sound effects according to their preferences, such as voiceover on guitar or keyboard instruments, and the tone of the instrument or piano, etc.
We determine our own microphone and determine the appropriate microphone distance based on the host's usage needs. If the sensitivity of the microphone is too high and the sound cannot be transmitted to the audience, the audience will also shout loudly, and the resonance noise that produces abnormal noise is also easy to accumulate dust, so this situation is quite safe.
Due to the prolonged use of microphones, the sensitivity of the microphone is required to be higher, which often leads to difficulty in picking up sound. For this reason, we have had the same problem based on the education of the school, but the layers are fragile and not easy to form a situation of significant hearing loss. Therefore, it is best to take another measure for maintenance.
Because the sensitivity of the microphone is not enough and the sound is not loud enough, some singers may experience sound distortion due to excessive noise. Therefore, the best microphone to choose is a professional singing microphone that is suitable for singing, using a microphone amplification circuit with bottom noise and echo, and ensuring the integration of the two.
The most common microphone: cardioid pointing, with an optimal pickup distance of 30-70cm, and a recommended distance of 1-6 meters. The gooseneck microphone has high sensitivity for ground to close range pickup. Adopting frequency response directional method, high sensitivity for long-distance pickup. High pickup sensitivity, with built-in environmental echo cancellation.
Noise parameter: Generally, it will reach a limited low-frequency range and needs to be used in conjunction with a high-gain audio system.
Impedance: 2 ohms output 500mV/600mV.
Maximum sound pressure level: 115dB (THD: 05% 1KHz.
