The dubbing microphone is a very important item for the announcer and host. Among the various types of microphones, there is no theorem that a certain microphone is the best. There are not only a wide variety of microphones, but also special functions, so you have to choose whether you want to use a microphone or buy a microphone. The choice of microphone is usually based on the occasion of use, the purpose of use, and the performance and sound quality of the microphone. There are currently two main types of microphones: condenser microphones and dynamic microphones.
According to the different principles of microphone energy conversion, it can be divided into electric type (moving coil type, belt type), capacitive type, electromagnetic type, semiconductor type, and voltage type. Electric microphones have a long history and are widely used. The true condenser microphone is favored by the majority of recording workers with its excellent performance and has now become the mainstream.
This type of microphone is currently the standard microphone in all recording studios in the world. The advantage is that the frequency range is wide, the sound is more delicate, and the recorded sound is particularly rich; the disadvantage is that it has higher environmental requirements and is more expensive than dynamic microphones. However, this type of microphone has become a mainstream product in the karaoke and live broadcast industry, and its market share is undoubtedly ranked first.
Condenser microphones generally have built-in amplifiers because the output of the capacitor unit is very weak. Condenser microphones require an external 48 V phantom power supply or battery. If you want extremely precise sound reception, then a small-diaphragm condenser microphone is the best choice. However, a more precise sound is not necessarily a more satisfying sound, and sometimes a precise sound does not sound so dynamic and powerful. However, if you want to record the sound of nature completely, a small-diaphragm condenser microphone should be a good choice.
Cheap and durable, this is a big bright spot. Those small microphones with 10 yuan free shipping are basically dynamic microphones. But its disadvantage is that the frequency range is narrow, the recorded sound is relatively dull, and many details are missing. It is generally used for recording instrument sounds with more bass.
The dynamic microphone does not need power supply. Its advantage lies in its simplicity and solidity. The disadvantage is that the diaphragm's response speed to fast-changing sound waves is not as fast as other types of microphones. Dynamic microphones are often used for vocal recording.
Things to pay attention to when choosing a microphone
1. The direction of the microphone
Omnidirectional: This kind of microphone can pick up 360°, but the noise will be more obvious. This kind of microphone is more suitable for multi-person chorus and instrumental accompaniment.
8-character direction: As the name implies, the front and back of the microphone can be recorded, while the left and right recordings will be weaker. This can effectively filter the sound on the side. For example, if you broadcast live on a noisy street, you don’t have to worry about the recorded sound being too noisy. And the omnidirectional microphone recorded the sound in the busy city, as if you were in the busy city, all kinds of cries haha.
Heart-shaped pointing: This pointing is versatile and suitable for almost all recording applications. Obtaining a dry sound signal as a cardioid direction mixed with a bad sound effect, with noisy fan noise in the background.
2. The diaphragm of the microphone (large diaphragm and small diaphragm)
Large diaphragm: This is suitable for recording human voices, and the details of the intermediate frequency are recorded well. However, the transient response is not ideal, especially on cheap microphones. For example, if you sing a high pitch hard, it will pop, but high-priced large-diaphragm microphones basically do not have these problems.
Small diaphragm: The sound recorded by this microphone is not so rich, but it is often used to record bass instruments, mainly because the transient response is better, such as sudden volume doubles, but no popping, and the sound is large and small, and it is not easy to lose signal.
3. Other parameters
Including transient range, dynamic range, signal-to-noise ratio, resistance, frequency response curve, response range, etc., and these parameters only have reference value for very professional microphones, especially in today's relatively open price, the price is basically Determines the level of the microphone, so there is no need to focus too much on parameter indicators.
Choosing a microphone must first be based on the purpose and purpose of use. For example, in general home recording, you do not necessarily need a very advanced microphone. You can use a dynamic or electret microphone. This type of microphone is low in price, easy to use, and strong. durable.
If it is a professional stage amplification or professional recording, a microphone with a high technical index must be selected, and the selection must also be combined with the sound source, the sound pickup environment and the connected equipment. Generally speaking, it is better to use condenser microphones to record musical instruments, and to use dynamic microphones to record voices, but this is not absolute. It depends on the type of musical instrument.
