Microphones

Microphones are transducers thatconvert sound into electrical signals. It is a vital part of any sound engineering or recording system. This article will focus on the GA38-30774-000, a model produced by the audio equipment manufacturer Moultone. This article will discuss the application field and working principle of the GA38-30774-000.

Application Field

The GA38-30774-000 is a professional microphone for sound recording and broadcast applications. It is designed to be used in any normal recording environment, from studio to live performance. It is also suitable for newsgathering and outdoor sports. This microphone has a wide frequency range, offering the user better sound reproduction and fidelity.

The GA38-30774-000 features a switchable low frequency roll off for reducing low-frequency rumble often found in studio recording. This allows the user to have greater control over the sound of the recording. The microphone also has a built in low pass filter to further reduce unwanted background noise. This makes the GA38-30774-000 an excellent choice for recording outdoors or in noisy environments.

Working Principle

The GA38-30774-000 is a condenser microphone which means it uses a diaphragm to convert sound waves into electrical signals. The diaphragm is attached to a metal capsule which is filled with an inert gas. The diaphragm vibrates when sound waves enter the capsule and this causes the electrical characteristics of the gas to change. This change in electrical characteristics is then converted into an electrical signal.

The GA38-30774-000 also features a built in impedance converter which matches the impedance of the microphone’s output to the impedance of the recorder’s or amplifier’s input. This allows the signal to be amplified properly and results in higher quality sound reproduction.

Finally, the GA38-30774-000 also includes an output transformer. This transformer helps to reduce hum and radio interference and also increases signal levels. This helps to reduce noise and ensures that the sound reproduced is of the highest quality.

Conclusion

The GA38-30774-000 is a professional microphone designed for sound recording and broadcast applications. It has a wide frequency range and features switchable low frequency roll off and a built in low pass filter. The microphone also includes a built in impedance converter and output transformer which ensures high quality sound reproduction. This makes the GA38-30774-000 an excellent choice for recording and broadcast applications.
