Microphones have been around as long as electronic amplifiers, and they are one of the most important elements of any audio system. The PMM-3738-VM1000-R is an example of a modern microphone that is designed for professional use in a wide variety of applications. This article will discuss the application field and working principle of the PMM-3738-VM1000-R.

Application Field

The PMM-3738-VM1000-R is designed for multi-purpose use, and it is particularly well suited for studio and live applications. Thanks to its low self-noise, high output level, and smooth frequency response, the PMM-3738-VM1000-R is capable of capturing both vocals and instruments with great accuracy. Its cardioid polar pattern helps to reduce ambient noise and room reflections, making it an ideal choice for live sound reinforcement applications. Additionally, thanks to its robust construction, the microphone is capable of withstanding the rigors of the road and can be used for outdoors broadcasts and recording.

Working Principle

The PMM-3738-VM1000-R utilizes a standard condenser microphone design. Its capsule contains a thin metal diaphragm and a fixed backplate, separated by a thin air gap. When sound waves cause the diaphragm to vibrate, the air gap narrows and widens, creating a variation in the electrical capacitance between the diaphragm and the backplate. This variation is converted to an electrical audio signal by a preamplifier built into the microphone. The converted signal is then sent to an external amplifier or mixer for further processing.

The PMM-3738-VM1000-R has a few unique design features that help to optimize it for different sound sources. Its cardioid polar pattern is a result of its optimized acoustic modeling. This helps to provide better feedback rejection and more gain before feedback. Additionally, its special high-end response technology helps to accurately capture subtle details in high-fidelity recordings. This allows the microphone to reproduce the sound of instruments and voices with great accuracy, making it a suitable choice for studio applications.

The PMM-3738-VM1000-R is a versatile microphone that is designed for both studio and live use. Its optimized acoustic modeling, cardiod polar pattern and high-end response technology allow it to accurately capture and reproduce sound in a variety of settings. With its robust construction, the PMM-3738-VM1000-R can handle the rigors of the road, making it an ideal choice for both studio and live applications.
