PreSonus PRM-1 - Precision Reference Omni Directional Condenser Microphone

PreSonus PRM-1 - Precision Reference Omni Directional Condenser Microphone

The PreSonus PRM1 Precision Reference Microphone is a special type of microphone that provides an accurate reproduction of a room's sound characteristics for use with audio-analysis tools. It employs a ¼”, 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 PRM1 has an all-metal chassis and comes with a clip, foam windscreen, and hard case.
