Under the meticulous design of PreSonus, the PRM1 Precision Reference Measurement Microphone stands as a testament to professional-grade audio equipment. This high-quality, durable microphone is engineered to deliver an exceptionally accurate reproduction of sound for critical audio-analysis applications. Whether you're utilizing real-time analyzers (RTAs), spectrographs, or other advanced audio-analysis tools, the PRM1 is a reliable and innovative choice for capturing the true acoustic characteristics of any room.
Crafted with a 1/4" pre-polarized electret-condenser capsule, the PRM1 requires phantom power to operate, ensuring consistent performance in professional studio and live performance settings. Its omnidirectional polar pattern is a key feature, offering equal sensitivity in all directions. This capability allows the microphone to adeptly measure both reflections and direct signals, providing a comprehensive depiction of the acoustic environment.
The PRM1 is capable of handling sound pressure levels up to 132 dB SPL without distortion, and it boasts a linear frequency response ranging from 20 Hz to 20 kHz. This flat response ensures that the microphone does not color the sound, making it an ideal tool for assessing the impact of a room or speaker system on audio output. By capturing all frequencies equally within its range, the PRM1 serves as an essential device for tuning sound systems to accurately reproduce audio tracks within a given space.
While the PRM1 has a narrow dynamic range, tailored for receiving test frequencies at a consistent level, it is not recommended for general recording purposes. Instead, its precision makes it the microphone of choice for sound system calibration and analysis. The PRM1 shines when paired with PreSonus Virtual StudioLive software featuring Smart Measurement Technology, as well as PreSonus StudioLive 24.4.2 and StudioLive 16.4.2 digital mixers. This combination creates a powerful, yet affordable, audio-analysis and correction system that professionals can trust.
In summary, the PreSonus PRM1 Precision Reference Measurement Microphone is a top-tier choice for audio professionals seeking a high-quality, durable, and reliable microphone for precise sound measurement. Its innovative design and compatibility with advanced audio-analysis software make it a standout product in the realm of professional audio equipment.
