Introduction
Thank you for purchasing the PreSonus® PRM1
RTA Microphone. This omnidirectional microphone
has been designed to provide an accurate
reproduction of a room’s sound characteristics for
use with audio-analysis tools, such as real-time
analyzers and spectrographs. Delivering a flat
frequency response from 20 Hz to 20 kHz and
featuring a ¼”, pre-polarized, electret condenser
capsule, the PRM1 is an excellent companion
to the Virtual StudioLive™ Smaart® System
Check Wizards and other analysis systems.
We appreciate the support you have shown
us through the purchase of this product.
Features
• ¼”, pre-polarized, electret condenser capsule
• Flat frequency response from 20 Hz to 20 kHz
• Low noise, low distortion
• Ideally suited for system analysis
and measurement
• All-metal chassis
Precautions
• Mute audio system output prior to
connecting or disconnecting the PRM1 or
engaging/disengaging phantom power.
• When operating in outdoor
environments, cover capsule with foam
windscreen to reduce wind noise.
• Attach to a mic stand when analyzing sound
systems to ensure accurate measurements.

About This Microphone
The PRM1 is a condenser microphone with a
flat frequency response and an omnidirectional
polar pattern. Let’s briefly define these terms.
Condenser Microphones
Condenser microphones such as the PRM1
require a power source, which can be provided
by an external power supply or using phantom
power, which is usually provided by a mixer,
preamplifier, or direct box. Phantom power is
sent over the same mic cable that carries the
audio signal; the term derives from the fact
that there is no visible power cable, and the
voltage is not perceptible in the audio path.
PreSonus StudioLive-series mixers provide
phantom power to every mic input,
including the talkback input utilized by the
Smaart System Check Wizards in VSL.
Flat Frequency Response
A microphone with a flat frequency response
captures all frequencies equally within its
specified response range, neither boosting
nor cutting frequencies, so it accurately
reproduces the incoming signal. While this
makes it ideal for measuring what a room or
speaker is doing to the outgoing signal in a
sound system, it is not necessarily the best
choice for recording specific instruments.
Frequency Response
Omnidirectional
The PRM1 has an omnidirectional polar
pattern, meaning it is equally sensitive in all
directions. This allows the microphone to
measure reflections, as well as direct signals,
providing an accurate depiction of the room.
