A Reference Microphone for Room Optimization and Sound System Tuning
The PreSonus PRM1 (Precision Reference Microphone) belongs to the very specific family of measurement microphones: its role is not to "flatter" a source, but to provide the most objective capture possible of an audio system in a given environment. Thanks to its omnidirectional directivity and a frequency response designed to remain linear, it becomes a relevant calibration tool for speaker alignment, system equalization, spectral coherence control, and room resonance analysis. Within the PreSonus ecosystem, it is particularly coherent when paired with the brand's analysis and mixing solutions, allowing a quick transition from reliable measurement to applied correction.
Who Benefits from the PRM1 and in Which Applications Does It Make a Difference?
The PRM1 is primarily aimed at stage managers, sound technicians, integrators, studios, and venues who want to tune a system methodically: pink noise measurement, frequency sweeps, cluster response verification, before-and-after treatment comparison, or checking coverage at different listening points. It is also useful in home studios to optimize a speaker-room pair (positioning, corrections, bass validation), provided it is used with appropriate analysis tools.
Important point: its dynamic range is intentionally narrow because the PRM1 is designed to receive fixed-level test signals. It is therefore not recommended for recording (vocals, instruments, ambient takes), unlike a classic studio condenser microphone. Its strength lies in precise and repeatable measurement, not artistic versatility.

Questions frequently asked
Is the PreSonus PRM1 suitable for measuring and tuning a sound reinforcement system?
Its specified flat frequency response from 20 Hz to 20 kHz and omnidirectional pattern are used to analyze the dispersion and acoustics of a room. It can be employed with pink noise signals or frequency sweeps to adjust a system.
Can vocals or instruments be recorded with this measurement microphone?
Its dynamic range is designed for fixed-level test signals, not for recording vocals, instruments, or ambient sounds. This model is intended for calibration and audio analysis.
What power supply and connection does the PRM1 require?
The output is via an XLR connector. The 1/4 inch pre-polarized electret condenser capsule is designed for measurement applications.
Can the microphone handle a high-level PA system?
With a maximum SPL of 132 dB, it is suitable for measurements on powerful sound reinforcement systems. This capacity reduces the risk of distortion during high-level testing.
What accessories come with the microphone?
A foam windscreen, a clip, and a hard case are included. The windscreen can be used during measurements exposed to drafts.
