Microphones are widely used in many different applications to capture sound in the environment and convert it into a signal that can be recorded or amplified. The WM7138IMSE/RV is a high-performance microphone available from Wolfson Microelectronics. It is designed to enable accurate and reliable sound capture in a range of environments. In this article, we will look at the application field and working principle of the WM7138IMSE/RV microphone.

The WM7138IMSE/RV is a microphone with a wide dynamic range that is able to accurately capture clear sound in a range of environments. Its low noise floor enables it to accurately capture quiet sounds, while its built-in acoustic overload protection guards against distortion due to sudden changes in volume or sudden loud sounds. This makes it ideal for a range of applications, such as recording in a studio or live environment, recording of interviews, as well as sound effects, and for video production.

The WM7138IMSE/RV is a pre-polarized condenser microphone, which means it uses a polarized backplate to sense sound waves in the environment. This type of microphone is a highly sensitive and accurate type of microphone, capable of capturing sound with a high signal-to-noise ratio. It also features a low-noise, low-distortion audio signal, giving it a wide dynamic range.

The WM7138IMSE/RV is also designed with an internal amplifier, which boosts the signal and helps to ensure a consistent level of sound throughout the response range. The internal amplifier is powered by a lithium-ion battery, which allows the microphone to be always on and ready to capture sound. The battery has a long life and does not require charging, making it ideal for long-term use.

The WM7138IMSE/RV also has a built-in impedance matching circuit, which ensures that the signal received by the microphone is compatible with other devices, such as audio mixers, amplifiers, and audio applications. This makes it easy to integrate the microphone into existing audio systems or audio production rigs.

The mic’s built-in acoustic overload protection ensures that loud sounds or sudden changes in volume do not cause distortion or other sound artifacts. The microphone also features a low-pass filter, which ensures that low-end noise such as wind and traffic sounds are filtered out before they can be recorded or amplified.

The WM7138IMSE/RV is designed for use in a range of audio applications such as recording, live sound recording, broadcasting, voice-over work, sound effects, or any situation where a wide dynamic range and consistent performance is required. It is also well suited for use in outdoor applications, as its robust construction and intolerance to wind and weather allow it to perform consistently, even in adverse conditions.

In conclusion, the WM7138IMSE/RV is a high-performance microphone from Wolfson Microelectronics designed to enable accurate and reliable sound capture in a range of environments. Its wide dynamic range, acoustic overload protection, low-pass filter, and internal impedance matching circuit make it an ideal choice for a variety of audio applications.
