The electric microphone is also a common microphone type in the ktv box. It is designed on the basis of the principle of electrostatics, and amplitudes and backboards form an electrical unit. The amplitude is very thin and sensitive to the vibrations of the acoustic waves. Generally built-in amplifiers because of the weak output telecommunications of the unit. A 48v vision power supply or battery is required。
The electron microphones have some advantages, such as high sensitivity, the ability to capture sound details, the sound quality, and the ability to provide a good high-frequency response. In addition, electro-capable microphones have the advantage of being small in size and light in weight to facilitate transport and movement。
When electric microphones are used in the ktv compartment, the following points need to be noted. First, because of the high sensitivity of the electric microphone, the microphone needs to be placed closer to the sound source to capture a clear sound. Second, because of the wide frequency of the response of the electric microphone, the appropriate microphone type is selected on the basis of different sound sources. For example, for voice singing, a more sensitive and responsive microphone model can be selected. Finally, it should be noted that the electric microphones require external power supply or battery power, and the corresponding power supply needs to be prepared in advance。
In short, in the ktv box, electric microphones are a common microphone type with high sensitivity and a wide frequency response. Care needs to be taken to select the appropriate microphone type and location to ensure sound clarity and stability. There is also a need to prepare the appropriate power supply to ensure that the microphone works properly。
