Microphones - CMR-2747PB-A Application Field and Working Principle
The CMR-2747PB-A is an omnidirectional condenser microphone made particularly for sound reinforcement projects. It has a cardioid polar pattern, made up of a low profile neodymium element and a tailor-made acoustic filter. As such, it provides an extended frequency response with excellent audio and quality performance. This microphone is best suited for speech, vocal, and acoustic applications in live sound reinforcement applications.
Application Fields of CMR-2747PB-A
The CMR-2747PB-A omnidirectional microphone is specifically designed for sound reinforcement applications. It is ideal for capture speech clarity during live performances such as speeches, music performances, theatre, karaoke, churches, conferences and other sound reinforcement projects. Additionally, it is suitable for vocal recording and live broadcast as it ensures clear and natural sound quality.
Working Principle
The CMR-2747PB-A condenser microphone features a low profile neodymium element which allows very detailed sound capturing and is tailored to ensure an extended frequency response with a precise clean output. The cardioid polar pattern helps to reject the background noise while amplifying the sound coming from its direct structure. It maintains a high sound quality for precise speech pick up and is optimized for sound reinforcement applications.
The low profile neodymium element is quite durable and more resistant to wind blasts and low frequency rumble in live environments. Furthermore, the frequency response of this microphone is tailored with an acoustic filter to create a minimized distortion level and ensure stable component output over a wide range of frequencies. The CMR-2747PB-A microphone also has a rise time of 5.5 milliseconds which ensures accurate transient response in loud, high impact environments.
Conclusion
The CMR-2747PB-A condenser microphone is an all-purpose microphone with extended frequency response, tailored acoustic filter and a cardioid polar pattern. This microphone is made specifically for sound reinforcement applications and to provide excellent audio and quality performance. It is ideal for speech, vocal and acoustic applications, and can also be used in live broadcast and vocal recordings.
