The PreSonus PRM1 Precision Reference Microphone is a special type of condenser microphone that provides an accurate reproduction of a room's sound characteristics for use with audio-analysis tools.
The PreSonus PRM1 Precision Reference Microphone employs a ¼”, pre-polarized electret-condenser capsule with an omnidirectional polar pattern, which allows the microphone to measure reflections, as well as direct signals up to 132 dB SPL. The PreSonus PRM1 has an all-metal chassis and comes with a clip, foam windscreen, and hard case.
What Makes the PRM1 Different from Most Mics?
Unlike mics you use for recording and live sound, the PreSonus PRM1 has a narrow dynamic range, since it is intended to receive test frequencies, such as pink noise, at a fixed level. As a result, it is not recommended for recording or performance—but it’s the right mic for analyzing a sound system’s performance. The PreSonus PRM1 exhibits linear (“flat”) frequency response between 20 Hz and 20 kHz, meaning it captures all frequencies equally within that range. Since it neither boosts nor cuts frequencies, it doesn’t color the sound, making it ideal for measuring what a room or speaker is doing to a sound system’s outgoing signal.
Designed for Use with Smaart and Other Audio Analysis Tools
While the PreSonus PRM1 can be used for a variety of measurement applications, such as MLSSA™, Spectrafoo™, and TEF™, it is especially recommended for use with the Smaart® System Check wizards that are integrated into PreSonus® UC Surface control software for StudioLive® AI and StudioLive RM mixers. With this combination, you can have a complete, powerful, and affordable, audio-analysis and correction system.
