PreSonus PRM1 Measurement Microphone

Unlike microphones used for recording and live audio, the PRM1 precision reference microphone is a special type of mic that provides an accurate reproduction of a room's sound characteristics for use with audio analysis tools. The PRM1 has a narrow dynamic range, as 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 is excellent for analyzing the performance of an audio system. The PRM1 features a linear ("flat") frequency response between 20 Hz and 20 kHz, so it captures all frequencies equally within that range. Because it does not boost or cut frequencies, it does not color the sound, making it ideal for measuring what a room or speaker is doing to an audio system’s output signal. It can be used for a variety of measurement applications, such as MLSSA, Spectrafoo, TEF, and Smaart System. The PRM1 employs a ¼-inch, pre-polarized, electret-condenser capsule with an omnidirectional polar pattern, which enables the mic to measure reflections and direct signals up to 132 dB SPL. The PRM1 has an all-metal chassis and comes with a clip, foam windscreen, and hard case. With the PRM1, a high-quality audio interface such as PreSonus® Studio series or StudioLive® mixers, and professional measurement software, you can have a powerful, affordable audio analysis and correction system.
