PreSonus PRM1 Precision Reference Microphone

Precision Reference Measurement Microphone 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. Since it is a condenser mic, it requires phantom power. The PRM1 employs a 1/4" pre-polarized electret-condenser capsule and 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 repr
