Unidirectional condenser microphone

Types of unidirectional condenser microphones

A unidirectional condenser microphone picks up sound from only one direction. It has different types of pickup patterns such as; cardioid, hypercardioid, heart-shaped, and supercardioid that come together to form a unidirectional pattern. This microphone is most commonly used in live performances and studio recordings. Unidirectional condenser microphones come in many varieties. They include the following:

• Cardioid condenser microphone:

  It is the most popular type. It allows sound to enter the microphone from the front and record in a heart-shaped pattern. The word cardioid comes from the Greek word for heart. A cardioid condenser microphone is ideal for amplifying sound from a particular source while keeping out background noise. It is frequently used in vocal performances and when miking musical instruments.

• Super cardioid condenser microphone:

  This type of microphone has a smaller front lobe compared to the cardioid condenser microphone. Because of this, it cancels out more of the sound coming from the back. The supercardioid pattern contains a pick up for sound at the rear. This can create unwanted noise from performers or sound sources that are behind the microphone. The super cardioid microphone is used to precisely amplify sound from a specific source in a space.

• Hyper cardioid condenser microphone:

  The hypercardioid condenser microphone has a very small front lobe. Overall, the hypercardioid pattern has complete cancellation of sound at the rear. This microphone is often used in environments where there is a very strong side noise, for example, at a music festival. It is important to use the hypercardioid microphone carefully since sounds from directly behind the microphone can be picked up.

• Subcapsular condenser microphone:

  This microphone is a unique kind of capsule that can be mounted on a surface, inside a musical instrument, or on a performer. The subcapsular condenser microphone has both a front and back diaphragm that are arranged horizontally. Unlike other unidirectional microphones, it cannot be pointed directly at a sound source.

Function and features

The unidirectional condenser microphone is popular for its various features that enhance quality sound production. Some common types include;

• Frequency response: This microphone has an extended frequency range that improves vocal and musical instrument recording. It provides a full-bodied sound that is natural. The frequency response varies depending on the intended use. For instance, the frequency response for speech ranges from 300Hz to 3000Hz, and for musical instruments, 20Hz to 20kHz is ideal.
• Sensitivity: This defines the ability of the microphone to pick up softer sounds. A sensitive microphone can capture lighter sounds, while less sensitive microphones may require louder sounds to respond.
• Signal-to-noise ratio (SNR): Microphones that have an excellent SNR ratio create little noise in the recording. This improves the quality of the recorded sounds, especially for speech and musical instruments.
• Power handling capabilities: Unidirectional microphones require power to function, and therefore, knowing the power handling capabilities is essential. Some microphones need external phantom power, while others use batteries.
• Connectors: When choosing a unidirectional condenser microphone, the connector type is important. Some common types are quarter-inch, XLR, USB, and mini XLR. Each connector type is used in different applications and knowing compatibility is essential.
• Impedance: This is important because it affects the microphone's ability to work with other equipment. High impedance microphones need to be plugged into a load, like a mixer or amp, while low impedance mics can be used on any input.
• Humidity and temperature tolerance: Some microphones are specifically made to withstand high temperatures and humidity when used in tough environments. These microphones have protective features to prevent damage.
• Weight and handling: If the condenser microphone will be used for portability purposes, considering weight is essential. Also, handling features like a built-in stand, shock mount, and carrying case make it easy to use.
• Built-in features: condenser microphones may have added features like eq settings, low cut filter, or pad that improve produced sound.

Scenarios of unidirectional condenser microphone

Unidirectional condenser microphones are used in many industries. Here are major applications of the microphone that every bulk buyer should know.
