Product information - Presonus PRM1

The PreSonus PRM1 is a measurement microphone that, unlike the standard, is both affordable and accurate.  It is designed for use with real-time analyzers (RTAs) and spectrographs.

The PRM1 uses a 1/4" pre-polarised electret-condenser diaphragm in an omnidirectional setup so that it picks up sound equally in all directions.  It can handle sound up to 132dB and its 20Hz-20kHz frequency response is extremely flat so as to provide an accurate representation of a rooms acoustic characteristics without colouring the sound.

The PRM1 has a limited dynamic range as it is desdigned for use with test tones such as pink noise so is not suitable for recording.  It is ideally used with measurement software like MLSSA, Spectrafoo, and TEF.

The PRM1 main features include:

  • Type - Black electret condenser
  • Element - Pressure, FET preamplifier
  • Polar Pattern - Omnidirectional
  • Polarity - Pin 2 output positive voltage (relative to Pin 3) when diaphragm receives positive pressure (moves inward)
  • Connector - 3-pin XLR Male
  • Frequency Response - 20 Hz to 20 kHz
  • Sensitivity (@ 1 kHz open-circuit voltage) - -37 dB/Pa (14 mV/Pa) 1 Pa=94 dB SPL
  • Rated Impedance - 200Ω
  • Minimum Load Impedance - 1,000Ω
  • EIN (A-weighted) - 26 dB
  • Max. SPL (1 kΩ load) - 132 dB SPL (THD ≤ 1%, 1 kHz)
  • Dynamic Range (1 kΩ load) - 106 dB
  • S/N Ratio - 70 dB
  • Phantom Power - 9-52V
  • Current Consumption - 2 mA
  • Length - 7.56” (192 mm)
  • Width - 0.83” (21 mm)
  • Weight - 5.3 oz (150g)
