A professional measurement tool.

The PRM1 Precision Reference Microphone is a special type of microphone that provides an accurate reproduction of a room's sound characteristics for use with audio-analysis tools. It 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 PRM1 has an all-metal chassis and

The Ideal Microphone For Your Acoustic Analysis

Plug in the PreSonus PRM1 RTA measurement microphone to analyze your room's acoustics with confidence. This ultra-precise, omnidirectional condenser microphone is the perfect match for the PreSonus Virtual StudioLive software, which uses Smaart Measurement Technology to help you tailor your sound system to the room. It's got a narrow dynamic range, intended to receive test frequencies at a fixed level. Because of that it's not recommended for recording situations, but Sweetwater does recommend tuning your sound system for the best performance with the PreSonus PRM1 RTA measurement microphone.

What makes the PRM1 different from most mics?

Unlike mics you use for recording and live sound, the 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 tuning a sound system to perform accurately in a venue. Unlike mics you use for recording and live sound, the PRM1 has a narrow dynamic range, since it is intended to receive test frequencies, such as pink noise, at a fixed level.

Designed for use with Smaart and other audio analysis tools.

While the 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.
