PreSonus PRM-1 - Precision Reference Microphone with Omnidirectional Polar Pattern and 20Hz to 20kHz Frequency Response in Black Finish

The PreSonus PRM-1 is a precision reference microphone designed to provide highly accurate and transparent sound reproduction, making it an essential tool for audio professionals who need to measure and analyze room acoustics. With its omnidirectional polar pattern and linear frequency response, the PRM-1 is ideal for use with real-time analyzers (RTAs), spectrographs, and other audio-analysis tools. It is perfectly suited for pairing with PreSonus UC Surface multi-touch mixer-control software featuring Smaart Measurement Technology, providing StudioLive digital mixer owners with a powerful, yet affordable, audio-analysis and room-correction system.

The PRM-1 utilizes a pre-polarized electret condenser capsule, offering a broad frequency response range from 20 Hz to 20 kHz, ensuring that the microphone captures every nuance of sound without introducing any coloration. Its omnidirectional polar pattern ensures uniform sensitivity to sound from all directions, making it an excellent choice for capturing accurate representations of room acoustics or live sound environments. Whether you're measuring room frequencies for acoustical analysis or calibrating a sound system, the PRM-1 delivers consistent, reliable results.

Engineered for durability and long-term performance, the PRM-1 features an all-metal chassis that protects the sensitive internal components. The microphone also boasts a dynamic range of 106 dB (at 1 kΩ load) and a maximum SPL of 132 dB, allowing it to handle both subtle and loud sounds with ease, all while maintaining a low distortion threshold (THD ? 1%, 1kHz). This ensures the PRM-1 can be used in a wide range of environments, from studio to live sound applications.

In addition to its excellent sound quality, the PRM-1 is designed for ease of use. It operates on a wide phantom power range of 9-52V, drawing just 2 mA of current, making it compatible with virtually any audio interface or mixer that supplies phantom power. The microphone comes complete with essential accessories, including a clip, a foam windscreen to reduce unwanted noise from air movement, and a hard case for safe transport and storage.

Whether you're a live sound engineer, studio owner, or acoustics consultant, the PreSonus PRM-1 is a valuable tool for precise audio measurement and system calibration. Its clear, uncolored sound reproduction and durable construction make it an indispensable part of any professional audio setup.
