The PreSonus PRM1 reference (measurement) microphone employs a ¼" pre-polarized electret-condenser capsule and delivers a linear frequency response between 20 Hz and 20 kHz. Like most measurement mics, it has an omnidirectional polar pattern. Sensitivity is rated at -37 dB/Pa, EIN (A-weighted) at 26 dB, S/N ratio at 70 dB, dynamic range at 106 dB, and maximum SPL at 132 dB SPL. The mic has an all-metal chassis and comes with a clip, foam windscreen, and hard case. Combined with PreSonus’ free Virtual StudioLive (VSL) mixer-control software with Smaart Measurement Technology, and a PreSonus StudioLive 24.4.2 and 16.4.2 digital mixer it offers a complete, powerful, and affordable, audio-analysis and correction system.
VSL's Smaart System Check Wizards step StudioLive 24.4.2 and 16.4.2 users through the process of viewing the frequency-response trace of a venue, calculating and setting delay-system timing, and verifying output connectivity. To use them, you need to connect a measurement microphone to the StudioLive mixer's Talkback input. That's where the PRM1 comes in. With the PRM1 mic, a StudioLive mixer, and VSL with Smaart, it's easy to do tasks that once required extensive engineering know-how.
The PRM1 is expected to ship in early January 2013, with an anticipated MAP/street price of $79.95.
