Types of Choir Microphones

When it comes to capturing the beautiful harmonies of a choir, choosing the right microphone is essential. There are several of microphones available, each with its own unique characteristics and benefits. In this section, we will explore the three main of choir microphones: dynamic, condenser, and ribbon microphones.

Dynamic Microphones

Dynamic microphones are a popular choice for capturing the sound of a choir due to their durability and versatility. These microphones work by using a diaphragm that is attached to a coil of wire. When sound waves hit the diaphragm, it vibrates and moves the coil, generating an electrical signal.

One of the advantages of dynamic microphones is their ability to handle high sound pressure levels without distorting the sound. This makes them ideal for capturing the powerful and dynamic performances of a choir. Additionally, dynamic microphones are less sensitive to ambient noise, making them suitable for recording in various environments.

Some popular dynamic microphones used for choir recordings include the Shure SM58 and the Sennheiser e835. These microphones offer excellent sound quality and are known for their reliability.

Condenser Microphones

Condenser microphones are another popular choice for recording choirs. They work by using a thin diaphragm that vibrates in response to sound waves. This diaphragm is placed close to a metal plate called a backplate, creating a capacitor. As the diaphragm vibrates, the distance between the diaphragm and the backplate changes, resulting in changes in capacitance and generating an electrical signal.

Condenser microphones are known for their high sensitivity and accuracy in capturing the subtle nuances of a choir’s performance. They are capable of reproducing a wide frequency range, making them suitable for capturing the full spectrum of vocal harmonies. However, condenser microphones are more sensitive to loud sounds and require a power source, often referred to as phantom power, to operate.

Popular condenser microphones used for choir recordings include the Neumann U87 and the Audio-Technica AT2020. These microphones offer exceptional detail and clarity, allowing for a true representation of the choir’s sound.

Ribbon Microphones

Ribbon microphones are a unique and less commonly used option for recording choirs. They work by using a thin strip of metal, typically made of aluminum, that vibrates in response to sound waves. This metal strip, known as the ribbon, is placed between two magnets, which create a magnetic field. As the ribbon vibrates, it generates an electrical signal.

Ribbon microphones are praised for their warm and natural sound reproduction, making them a popular choice for capturing the rich and full-bodied sound of a choir. They excel at capturing high-frequency details and have a smooth frequency response.

It’s important to note that ribbon microphones are delicate and require careful handling. They are more sensitive to loud sounds and can be easily damaged by phantom power or rough handling. However, with proper care, ribbon microphones can provide stunning results for choir recordings.

Some popular ribbon microphones used for choir recordings include the Royer R-121 and the AEA R84. These microphones offer exceptional clarity and a vintage sound that adds a unique character to the choir’s performance.

Best Placement for Choir Microphones

When it comes to capturing the rich and harmonious sound of a choir, the placement of microphones plays a crucial role. Proper placement ensures that each voice is captured accurately, resulting in a balanced and natural sound reproduction. In this section, we will explore three different microphone placement techniques: overhead placement, boundary placement, and individual microphone placement.

Overhead Placement

Overhead placement is a popular choice for capturing the sound of a choir, especially in larger spaces such as churches or concert halls. This technique involves suspending microphones from the ceiling or using microphone stands positioned above the choir. By placing the microphones overhead, you can capture the overall sound of the choir, including the blend and balance of voices.

One advantage of overhead placement is that it provides a more natural sound representation, as it simulates the way we hear the choir as listeners. It allows the microphones to capture the sound as it spreads and interacts with the acoustics of the room. This technique is particularly effective for capturing the fullness and depth of the choir’s sound.

To achieve optimal results with overhead placement, it is important to position the microphones evenly across the width of the choir and at an appropriate height. Experimentation may be necessary to find the sweet spot where the microphones capture the desired balance between individual voices and the overall choir sound.

Boundary Placement

Boundary placement, also known as boundary microphone technique, involves positioning microphones on flat surfaces near the choir, such as the floor or the walls. These microphones are designed to be placed in close proximity to the reflective surface, taking advantage of the boundary effect to capture the sound.

The boundary effect occurs when sound waves hit a surface and reflect back, resulting in increased sensitivity and directivity. By placing boundary microphones on the floor or walls near the choir, you can capture a more focused and intimate sound. This technique is particularly useful in spaces with limited overhead clearance or when you want to highlight specific sections of the choir.

When using boundary placement, it is important to ensure that the microphones are placed at an appropriate distance from the reflective surface. This distance will depend on the specific microphone and the desired sound. Experimentation and careful positioning are necessary to achieve optimal results.

Individual Microphone Placement

In some cases, individual microphone placement may be the preferred option for capturing the sound of a choir. This technique involves using separate microphones for each vocalist or section of the choir. Each microphone is positioned in close proximity to the source, capturing the nuances and details of each voice.

Individual microphone placement provides the highest level of control and allows for precise sound reinforcement. It is particularly useful in situations where specific voices or sections need to be highlighted, or when the choir is performing with instruments that require individual amplification.

When using individual microphone placement, it is important to consider the polar pattern and frequency response of the microphones. Different voices may require different microphone characteristics to achieve optimal results. Additionally, proper microphone technique is essential to ensure consistent sound quality and avoid interference between microphones.

Factors to Consider When Choosing Choir Microphones

When it comes to choosing the right microphones for a choir, there are several that need to be taken into consideration. These can greatly impact the overall sound quality and performance of the choir. In this section, we will explore three important : polar pattern, frequency response, and sensitivity.

Polar Pattern

The polar pattern of a microphone refers to its sensitivity to sound coming from different directions. Different polar patterns are suitable for different recording situations, and it is important to choose the right one for a choir.

One commonly used polar pattern for choirs is the cardioid pattern. This pattern picks up sound from the front of the microphone while rejecting sound from the sides and rear. This is ideal for capturing the sound of the choir while minimizing background noise and feedback.

Another polar pattern that can be suitable for choirs is the omnidirectional pattern. This pattern picks up sound from all directions equally. It is useful when capturing the full sound of the choir in a more natural and spacious way.

Lastly, there is the figure-8 polar pattern, which picks up sound from the front and rear of the microphone while rejecting sound from the sides. This pattern can be useful when recording a choir in a stereo setup or when trying to capture the blend of voices from both sides of the choir.

Frequency Response

The frequency response of a microphone refers to the range of frequencies it can accurately reproduce. For choirs, it is important to choose microphones with a wide frequency response to capture the full range of vocal tones.

A microphone with a flat frequency response is often preferred for choirs. This means that the microphone accurately reproduces all frequencies without emphasizing or attenuating any particular range. This ensures that the natural sound of the choir is faithfully captured.

Some microphones have a tailored frequency response, which means they are designed to enhance or attenuate certain frequencies. While these microphones can be useful in specific recording situations, they may not be the best choice for capturing the true sound of a choir.


The sensitivity of a microphone refers to its ability to convert sound pressure into an electrical signal. A higher sensitivity microphone will pick up softer sounds more easily, while a lower sensitivity microphone may require louder sounds to be captured effectively.

When choosing microphones for a choir, it is important to consider the sensitivity of the microphone in relation to the performance environment. If the choir will be performing in a large, acoustically live space, a microphone with higher sensitivity may be preferable to capture the nuances of the voices. On the other hand, if the choir will be performing in a controlled studio environment, a microphone with lower sensitivity may be more appropriate to avoid picking up unwanted background noise.

It is also worth noting that sensitivity can be adjusted using microphone preamps or gain controls on a mixing console. This allows for fine-tuning the microphone’s response to the specific needs of the choir and the recording environment.

Common Issues with Choir Microphones

When it comes to using choir microphones, there are several common issues that can arise. These issues can affect the overall sound quality and performance of the choir. In this section, we will discuss three common issues: feedback, background noise, and uneven sound distribution.


One of the most frustrating issues that can occur when using choir microphones is feedback. Feedback happens when the sound from the speakers is picked up by the microphones and then amplified again, creating a loop of sound that results in a high-pitched squeal or howling noise. This can be especially problematic during choir performances where the microphones are placed close to the speakers.

To minimize feedback, it is important to properly position the microphones and speakers. Placing the microphones at a distance from the speakers and angling them away can help reduce the chances of feedback occurring. Additionally, using microphones with a cardioid polar pattern can also help in minimizing feedback, as they are less likely to pick up sound from behind.

Background Noise

Another issue that can affect the quality of the choir’s performance is background noise. Background noise can come from a variety of sources, such as audience chatter, HVAC systems, or other performers on stage. This noise can interfere with the clarity and intelligibility of the choir’s singing.

To address background noise, it is essential to choose microphones with a high signal-to-noise ratio. Microphones with a high signal-to-noise ratio can effectively capture the sound of the choir while minimizing the pickup of ambient noise. Additionally, using directional microphones, such as cardioid or supercardioid microphones, can help in reducing the pickup of unwanted background noise.

Uneven Sound Distribution

Achieving an even sound distribution across the choir is crucial for a balanced and harmonious performance. Uneven sound distribution can occur when some choir members are louder or closer to the microphones than others, resulting in an unbalanced mix.

To ensure even sound distribution, it is important to properly position the microphones. Overhead placement, where the microphones are suspended above the choir, can help capture a more balanced sound. Individual microphone placement, where each singer has their own microphone, can also be used to ensure that each voice is captured evenly.

In addition to microphone placement, proper microphone technique is essential. Choir members should be trained to sing towards the microphones and maintain a consistent distance to ensure that their voices are captured evenly. Using pop filters can also help in reducing plosive sounds, resulting in a more even sound distribution.

In summary, feedback, background noise, and uneven sound distribution are common issues that can arise when using choir microphones. By addressing these issues through proper microphone placement, choosing the right microphones, and training choir members in proper microphone technique, these issues can be minimized, resulting in a better sound quality and performance for the choir.

Tips for Proper Microphone Technique in Choirs

Maintaining Proper Distance

One of the most important aspects of achieving optimal sound quality in a choir performance is maintaining the proper distance between the singers and the microphones. This can greatly affect the clarity and balance of the sound captured.

To maintain proper distance, it is crucial to ensure that the microphones are placed at an appropriate height and distance from the choir. Generally, a distance of approximately 12 to 18 inches is recommended. This allows for a good balance of capturing the individual voices while also capturing the overall blend of the choir.

It is also important to consider the polar pattern of the microphones when determining the distance. Omni-directional microphones capture sound from all directions, while cardioid microphones are more focused and capture sound primarily from the front. Understanding the polar pattern of the microphones being used can help determine the optimal distance for capturing the desired sound.

Singing Towards the Microphone

Another key technique for achieving excellent sound quality in a choir performance is for the singers to sing towards the microphone. This helps to ensure that their voices are properly captured and projected.

Encouraging the singers to sing towards the microphone can be done through proper positioning and guidance. The microphones should be positioned in a way that allows the singers to easily see them and understand where to direct their voices. This can be especially important for larger choirs where singers may be spread out across the stage.

In addition, choir directors or sound engineers can provide guidance during rehearsals and performances, reminding the singers to project their voices towards the microphones. This helps to ensure that the sound is captured effectively and projected to the audience without any loss in quality.

Using Pop Filters

Pop filters are an essential accessory when it comes to proper microphone technique in choirs. They help to minimize plosive sounds, such as the harsh “p” and “b” sounds, which can cause distortion and unwanted noise in the recorded or amplified sound.

Pop filters are typically placed in front of the microphones, acting as a barrier between the singer’s mouth and the microphone. They effectively reduce the impact of plosive sounds by dispersing the air and preventing it from directly hitting the microphone capsule.

When using pop filters, it is important to position them correctly. They should be placed about two to three inches away from the microphone, ensuring that they are in the path of the singer’s breath. This distance helps to capture the singer’s voice clearly while still providing effective protection against plosive sounds.

Additionally, it is essential to regularly clean and maintain the pop filters to ensure optimal performance. Dust and debris can accumulate on the filters over time, affecting their effectiveness. Regular cleaning with a damp cloth or using a gentle cleaning solution can help to keep them in top condition.

In summary, maintaining proper distance, singing towards the microphone, and using pop filters are key techniques for achieving excellent sound quality in choir performances.
