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.

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.
