Introduction

The TO-30031-000 is a type of microphone. Microphones are devices that convert sound waves into electrical signals, enabling sound to be transmitted and amplified. The TO-30031-000 application field and working principle is just one example of how microphones are used and how they operate.

Overview of TO-30031-000

The TO-30031-000 is designed to be used in a variety of fields, including broadcast, recording, and theatre. It is a cardioid condenser microphone with a unidirectional pickup pattern that allows for more natural sounding recordings. The capsule is a back-electret type and contains an electronics package that allows it to be impedance-free when powered. This type of microphone is equipped with phantom power and uses both balanced and unbalanced cable inputs.

Working Principle

The working principle of the TO-30031-000 microphone is based on two basic concepts - transmembrane pressure and electrochemical conversion. When sound waves enter the microphone, the membrane vibrates in response, creating a pressure differential across its two sides. This increases the electrostatic pressure, which is then converted into an electrical signal by the microphone’s transducer.

Frequency Range

The TO-30031-000 has a frequency range of 20Hz to 20kHz and is capable of reproducing a wide range of sound frequencies. The microphone is designed to capture sounds accurately and with a low noise floor. The frequency response of this type of microphone is typically quite flat, meaning it reproduces sound with minimal deviation from its original frequency. This makes it well-suited for capturing sound in various environments and for various applications.

Phantom Power

The TO-30031-000 microphone requires phantom power to operate. Phantom power is a DC voltage supply that is sent to the microphone through its cable. The power source is usually a mixing board or an audio interface. Phantom power can range from 48V to 60V and is used to power active microphones. The phantom power provides the necessary voltage for the microphone’s transducer, which then converts the sound waves into electrical signals.

Low Noise Floor

The TO-30031-000 has a low noise floor providing excellent signal-to-noise ratio. This low noise tolerance is a desirable trait for live recording situations where background noise can interfere with the sound signal. The low noise floor enables the microphone to accurately record sounds, even in noisy environments. The microphone is also equipped with an isolating pop filter, which helps reduce breath noises and other background noises to provide a higher quality recording.

Conclusion

The TO-30031-000 microphone is designed for broadcast, recording, and theatre applications. It has a unidirectional pickup pattern, a wide frequency range, and a low noise floor. The microphone requires phantom power and is capable of producing high quality recordings. This type of microphone is well-suited for capturing sound accurately in various environments and applications.
