The PRM1 Precision Reference Microphone from PreSonus 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. Unlike mics designed for recording or performance, the PRM1 has a narrow dynamic range intended to receive test frequencies, making it the perfect mic for analyzing a sound system’s performance. Since it neither boosts nor cuts frequencies, it doesn’t color the sound, making it ideal for measuring what a room or speaker is doing to a sound system’s outgoing signal.
