Microphones play a central role in the world of audio recording and event technology. They are the first link in the sound recording chain and convert the sound into an electrical voltage that can be further processed or amplified. In this article, we will take an in-depth look at microphones: How they work, what different types there are, which models are particularly popular, which manufacturers are leading, what you need to look out for when setting up microphones and which accessories are necessary.
What are microphones and how do they work?
Microphones are devices that convert sound waves into electrical signals. They essentially consist of a membrane that is made to vibrate by sound waves. These vibrations are then converted into an electrical signal that can be amplified and recorded.
There are various principles by which microphones work, but the most common are:
Dynamic microphones: These microphones use a moving coil that oscillates in a magnetic field. They are robust and insensitive to moisture and extreme temperatures.
Condenser microphones: These microphones use a condenser capsule that generates electrical charges. They are more sensitive and offer a higher sound quality, but are also more susceptible to environmental influences.
Ribbon microphones: These microphones use a thin metal ribbon stretched between magnets. They are very sensitive and offer a warm, natural sound.
What different types of microphones are there and what are they used for?
There are a variety of microphone types that are suitable for different applications:
1. dynamic microphones:
– Vocals: Dynamic microphones like the Shure SM58 are the workhorses of vocal recording and live performance. They are robust and can handle loud sound sources without any problems.
– Instruments: Dynamic microphones such as the Shure SM57 are ideal for drums and guitar amplifiers.
2. condenser microphones:
– Studio recordings: Large diaphragm condenser microphones such as the Neumann U87 are the gold standard for studio recordings of vocals and acoustic instruments.
– Overhead and room recordings: Small diaphragm condenser microphones such as the AKG C451 are often used for drum overheads and room recordings.
3. ribbon microphones:
– Studio recordings: Ribbon microphones such as the Royer R-121 are ideal for recording guitar amplifiers and wind instruments, as they offer a natural and warm sound.
4. lavalier microphones:
– Broadcast and theater: These small clip-on microphones are ideal for interviews, presentations and theater performances, as they are unobtrusive and still offer good sound quality.
5. directional microphones:
– Film and television: Shotgun microphones such as the Sennheiser MKH 416 are often used in film production to record sound from a specific direction and minimize background noise.
What are the most popular microphone models?
There are numerous microphones on the market, but some models have proven themselves particularly well due to their reliability and sound quality:
– Shure SM58: A classic among dynamic vocal microphones, known for its robustness and excellent sound quality.
– Shure SM57: A versatile dynamic microphone used for both vocals and instruments.
– Neumann U87: A large diaphragm condenser microphone that is used in many professional studios worldwide.
– AKG C414: A versatile condenser microphone with switchable polar patterns, ideal for a wide range of applications.
– Royer R-121: A ribbon microphone known for its warm sound quality and its suitability for recording guitar amplifiers and wind instruments.
– Sennheiser MKH 416: A shotgun microphone that is often used in film production and is valued for its directionality and fidelity.
Which microphone manufacturers are there?
The world of microphones is dominated by several leading manufacturers known for their quality and innovation:
– Shure: An American manufacturer known for its robust and versatile microphones such as the SM58 and SM57.
– Neumann: A German manufacturer famous for its high-quality condenser microphones such as the U87.
– AKG: An Austrian manufacturer known for its versatile condenser microphones such as the C414.
– Sennheiser: A German manufacturer that offers a wide range of microphones, including the popular MKH 416 shotgun microphone.
– Royer: An American manufacturer specializing in ribbon microphones such as the R-121.
– Audio-Technica: A Japanese manufacturer known for its reliable and affordable microphones such as the AT2020.
What should you pay attention to when setting up microphones and what should you avoid at all costs?
The correct placement of a microphone is crucial for the sound quality. Here are some tips and things you should bear in mind:
1. observe the directional characteristic:
Microphones have different directional characteristics (e.g. cardioid, omnidirectional, figure of eight), which influence the way they pick up sound. Select the correct directional characteristic for your application and align the microphone accordingly.
2. distance and angle: The distance between the microphone and the sound source has a significant influence on the sound quality. Too little distance can lead to clipping and an unpleasantly close sound, while too much distance results in a thin and reverberant sound. The angle of the microphone to the sound source can also change the sound.
3. avoid feedback: Make sure that speakers are not pointed directly at the microphone to avoid feedback.
4. pop filter and windscreen: When recording vocals, it is important to use a pop filter to reduce plosives (explosive consonants such as “P” and “B”). A windbreak should be used outdoors or in strong draughts.
5. avoid sources of interference: Make sure to keep the microphone away from sources of interference such as air conditioning systems, computers or other sources of noise.
What accessories are required for microphones?
The right accessories are essential for successful miking. Here are some important components:
1. microphone stands: A stable microphone stand is essential to hold the microphone securely and in the correct position. There are different types of tripods, including table tripods, boom stands and floor stands.
2. microphone cable: High-quality microphone cables are important to avoid signal loss and interference. Make sure the cable is well shielded and the right length for your application.
3. pop filter: A pop filter helps to minimize plosive sounds and improve the recording quality. It is mounted in front of the microphone and serves as protection against strong air shocks.
4. shockmounts: A shockmount isolates the microphone from mechanical vibrations and shocks that could otherwise be picked up as unwanted noise.
5. windscreen: A windscreen is necessary when recording outdoors or in highly ventilated environments to reduce wind noise.
6. preamplifier: A microphone preamplifier amplifies the signal of a microphone to a usable level. High-quality preamplifiers offer better sound quality and lower noise.
7 DI boxes: A DI box (Direct Injection) is used to convert high-impedance instrument signals into low-impedance signals suitable for connection to a mixing console or recording device.
Microphones are indispensable tools in the world of audio recording and event technology. Choosing the right microphone and handling it correctly are crucial for the quality of the recorded or amplified sounds. By knowing the different types of microphones, their applications and the correct setup, as well as the necessary accessories, you can ensure that your audio recordings are always first-class.
