PRM1 “Precision Reference Microphone” real time
It is a professional condenser microphone specially designed for use with audio analysis tools such as analyzers (RTA) and spectrographs, and capable of capturing the sound characteristics of spaces very accurately.
The PRM1 has a 1/4″ pre-polarized electret-condenser capsule that needs phantom power. Thanks to its omnidirectional pattern, it is equally sensitive to sounds coming from all directions. In this way, the PRM1 detects reflections as well as direct signals, giving a very realistic view of the room. can make a description.
The PRM1 can withstand 132 dB SPL sound and has an almost linear “flat” frequency response from 20HZ to 20kHz.
The PRM1 has a very narrow dynamic range as it is designed for test signals such as “pink noise”. Therefore, it is not recommended to use it for recording. In addition, it is the most ideal microphone for the measurements to be made in order for the sound systems to give the most accurate sound in the place where they are located.
PRM1 can be used with measurement programs such as MLSSA™, Spectrafoo™, and TEF™ especially Smaart Measurement Technology™ using Presonus Virtual StudioLive™ software and StudioLive 24.4.2 and StudioLive 16.4.2 digital mixers. With this combination, you have an extremely powerful, accessible audio analysis and correction system.
PRM1 has an all metal chassis and comes with clip, foam windshield and hardcase.
