The 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 such as real-time analyzers (RTAs) and spectrographs.

The PRM1 employs a ¼” pre-polarized electret-condenser capsule and requires phantom power. It has an omnidirectional polar pattern, meaning it is equally sensitive in all directions. This allows the microphone to measure reflections, as well as direct signals, providing an accurate depiction of the room.

This mic can handle up to 132 dB SPL and exhibits linear (“flat”) frequency response between 20 Hz and 20 kHz, so it won’t color the sound.

The PRM1 has a narrow dynamic range, since it is intended to receive test frequencies, such as pink noise, at a fixed level. Therefore it is not recommended for recording purposes. But it’s the right mic for tuning a sound system to reproduce those tracks accurately in a room.

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 PreSonus Virtual StudioLive™ software with Smaart Measurement Technology™ and PreSonus StudioLive 24.4.2 and StudioLive 16.4.2digital mixers. With this combination, you can have a complete, powerful, and affordable, audio-analysis and correction system.

The PRM1 has an all-metal chassis and comes with a clip, foam windscreen, and hard case.
