PreSonus PRM1 Measurement Microphone

Unlike microphones used for recording and live audio, the PRM1 precision reference microphone is a special type of microphone that provides accurate reproduction of a room's sonic characteristics for use with audio analysis tools. The PRM1 has a narrow dynamic range, as it is designed to receive test frequencies, such as pink noise, at a fixed level. Consequently, 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 frequency response ("flat") between 20 Hz and 20 kHz, so it captures all frequencies equally within that range. Since it neither boosts nor cuts frequencies, it does not color the sound, making it ideal for measuring what a room or speaker is doing to the output signal of an audio system. 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 pattern, which allows the microphone to measure reflections and direct signals up to 132 dB SPL. The PRM1 has an all-metal frame and comes with a clip, foam windscreen and hard case. With PRM1, a high-quality audio interface such as the PreSonus® Studio series or StudioLive® mixers and professional measurement software, you can have a powerful and cost-effective audio analysis and correction system.
