Introduction
Thank you for purchasing the PreSonusĀ® PRM1
RTA Microphone. This omnidirectional microphone
has been designed to provide an accurate
reproduction of a roomā€™s sound characteristics for
use with audio-analysis tools, such as real-time
analyzers and spectrographs. Delivering a ļ¬‚at
frequency response from 20 Hz to 20 kHz and
featuring a Ā¼ā€, pre-polarized, electret condenser
capsule, the PRM1 is an excellent companion
to the Virtual StudioLiveā„¢ SmaartĀ® System
Check Wizards and other analysis systems.
We appreciate the support you have shown
us through the purchase of this product.
Features
ā€¢Ā¼ā€, pre-polarized, electret condenser capsule
ā€¢Flat frequency response from 20 Hz to 20 kHz
ā€¢Low noise, low distortion
ā€¢Ideally suited for system analysis
and measurement
ā€¢All-metal chassis
Precautions
ā€¢Mute audio system output prior to
connecting or disconnecting the PRM1 or
engaging/disengaging phantom power.
ā€¢When operating in outdoor
environments, cover capsule with foam
windscreen to reduce wind noise.
ā€¢Attach to a mic stand when analyzing sound
systems to ensure accurate measurements.

About This Microphone
The PRM1 is a condenser microphone with a
ļ¬‚at frequency response and an omnidirectional
polar pattern. Letā€™s brieļ¬‚y deļ¬ne 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,
preampliļ¬er, 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 ļ¬‚at frequency response
captures all frequencies equally within its
speciļ¬ed 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 speciļ¬c instruments.
Omnidirectional
The PRM1 has an omnidirectional polar
pattern, meaning it is equally sensitive in all
directions. This allows the microphone to
measure reļ¬‚ections, as well as direct signals,
providing an accurate depiction of the room.

Mic Position and Room Analysis
Improper mic placement when analyzing a sound
system can result in the system appearing to
have problems that donā€™t actually exist. Below
is a quick reference for proper mic placement.
Primary Mic Position
This is the main reference point for a speaker and
can be used as a single, ā€œrepresentativeā€ position.
Your goal in setting the primary mic position
is to ļ¬nd a point that puts the microphone in
the center (on axis) of a speakerā€™s throw, within
the listening area. In other words, you want to
put the microphone smack dab in the middle
of where your speaker sounds its best.
Secondary Mic Position
Secondary mic positions provide your system
analysis with more information to get a more
ā€œthree-dimensionalā€ view of your system.
These can be on- or oļ¬€-axis measurements
of a speaker within the listening area. Avoid
using locations outside the core coverage
area of your system, or on the edges.
With any mic position, avoid creating
position-dependent anomalies.

Ground Bounce
Ground reļ¬‚ections, or ā€œground bounce,ā€ become an
issue when a speaker is ļ¬‚own and angled down.
The proper mic position, in this case, will also
catch the reļ¬‚ection of the signal oļ¬€ the ļ¬‚oor.
Reļ¬‚ection
arrives
~4ms late...
In this case, you can choose from three options:
ā€¢Block the reļ¬‚ection with a baļ¬„e.
ā€¢Do a ground-plane measurement.
ā€¢Do a multi-point measurement to
randomize the eļ¬€ect of the ļ¬‚oor bounce.
