PreSonus PRM1 precision reference microphone

Introducing the PreSonus PRM1 precision reference microphone

The PRM1 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 analysers (RTAs) and spectrographs.

It has an omnidirectional polar pattern and exhibits linear frequency response between 20 Hz and 20 kHz, so it won’t colour the sound.

With this mic and PreSonus UC Surface multi-touch mixer-control software with Smaart Measurement Technology, PreSonus StudioLive digital mixer owners can have a powerful and affordable audio-analysis and correction system.

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

A professional measurement tool

The PRM1 precision reference microphone employs a ¼-inch, 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 perfect tool for analysing a sound system’s performance

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 recommended for analysing a sound system’s performance.

The PRM1 exhibits linear (“flat”) frequency response between 20 Hz and 20 kHz, meaning it captures all frequencies equally within that range. Since it doesn’t boost or cut frequencies, it doesn’t colour the sound, making it ideal for measuring what a room or speaker is doing to a sound system’s outgoing signal.
