Introduction

The EM-9745UN is a high-performance condenser sound microphone designed for remote audio recording and live sound reinforcement applications. The microphone is equipped with a cardioid and omnidirectional polar pattern. The microphone is built with superior acoustic design elements to deliver excellent audio performance and reliable operation. It is easy to mount, and has a low-noise circuit design to minimize background noise and minimize the potential for interference from nearby audio sources.

Features and Benefits of the EM-9745UN

The EM-9745UN microphone offers many features and benefits. The cardioid polar pattern provides excellent rejection of off-axis noise, capturing sound more accurately and creating a more natural sound. The omnidirectional polar pattern captures audio equally from all directions, providing clear, accurate audio capture in both nearfield and farfield applications. The low-noise circuitry minimizes noise from nearby audio sources, and the ultra-low noise design ensures that the potential for interference from nearby audio sources is minimized. Additionally, the microphone is easy to mount, featuring a standard thread mount for convenience.

Applications

The EM-9745UN microphone is ideally suited for both live sound reinforcement and recording applications. For live sound applications, the microphone is great for capturing sound sources such as vocalists, guitar amplifiers, and acoustic drums. The low-noise circuitry and cardioid polar pattern make the microphone a great choice for capturing instrumentalists in close proximity to loudspeakers. For recording applications, the microphone excels at capturing acoustic instruments, vocals, and reverb tails.

Working Principle

The EM-9745UN microphone utilizes a condenser element to capture sound. The condenser element is a very thin conductive material, usually aluminum, that can capture sound waves. When sound waves hit the element, the diaphragm of the element vibrates, producing an electrical signal that is sent to the microphone’s preamp circuit. The preamp circuit amplifies the signal and sends it to an external audio source.

Conclusion

The EM-9745UN microphone is a great choice for both live sound reinforcement and remote audio recording applications. It offers features such as a cardioid and omnidirectional polar pattern, low-noise circuitry, and an easy-to-mount design. The microphone utilizes a condenser element to capture sound, and its signal is amplified by the microphone’s preamp circuit before being sent to an external audio source. The EM-9745UN is an excellent choice when looking for a high-performance sound microphone for any application.
