PMM-3738-WP-2-R Microphone is used in many areas and is widely applied in audio production, surveillance and broadcasting system. This type of microphone is a type of pre-polarized condenser microphone that works with either an energized diaphragm or an unenergized diaphragm. In the energized diaphragm application, an energized diaphragm is placed in front of a condenser plate that is charged with a stable voltage. The diaphragm then moves towards the condenser plate, changing the capacitance of the system and the amount of charge that is transferred through the microphone.

In the unenergized diaphragm application, the diaphragm is placed in front of a capacitive plate that is charged by an external voltage source. In this case, the capacitance of the system does not change, but the charge on the plate, and hence on the diaphragm, will change with every movement of the diaphragm. This means that the electric field between the diaphragm and plate will be proportional to the sound pressure that is incident upon the diaphragm.

Another important feature of the PMM-3738-WP-2-R microphone is its high input impedance. This allows it to work in a wide range of audio frequencies, resulting in a high quality sound even when recording at lower frequencies. This feature is also beneficial when recording in challenging acoustic environments, as it ensures that the microphone does not overload or produce distorted recordings.

The PMM-3738-WP-2-R microphone is also highly sensitive and is capable of detecting even the smallest of sounds. This makes it a great choice for a variety of applications, such as recording dialogues in low-noise environments, capturing acoustic instrument recordings, and capturing subtle background vocal sounds. Additionally, it has a remarkable frequency response, spanning from 20Hz to 20kHz, ensuring a full range of sound reproduction.

The PMM-3738-WP-2-R microphone is an ideal choice for a variety of audio production applications, such as studio and live recordings, podcasts, broadcast production, dubbing and voice-over work. Additionally, it is also an excellent choice for security systems, surveillance systems, and remote monitoring. Its robust construction and compact size makes it perfect for use in tight spaces. Additionally, its low self-noise and high dynamic range make it an ideal choice for applications requiring ultra-sensitive audio capture.

The PMM-3738-WP-2-R microphone is an excellent choice for any audio production or surveillance system, as it is highly reliable and provides high quality audio recordings. Its low self-noise and high signal-to-noise ratio makes it an ideal choice for capturing subtle sounds in challenging acoustic environments. Additionally, its small size and robust construction also makes it an excellent choice for high-security and remote monitoring applications. Overall, the PMM-3738-WP-2-R microphone is a versatile and well-rounded microphone that is capable of providing high quality audio recordings in a wide range of audio production and surveillance applications.
