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 such as the PRM1
requireapowersource,whichcanbeprovided
by an external power supply or using phantom
power, which is usually provided by a mixer,
preamplifier, or direct box. Phantompower 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,
Omnidirectional
The PRM1 has an omnidirectional polar
pattern,meaning it is equally sensitivein all
directions. This allows the microphone to
measure reflections, as well as direct signals,
providingan accurate depiction of the room.

FlatFrequency Response
Amicrophonewitha flatfrequencyresponse
captures all frequencies equally within its
specifiedresponserange,neitherboosting
nor cutting frequencies, so it accurately
reproduces the incoming signal.Whilethis
makesit ideal for measuring what a room or
speaker is doing to the outgoing signal in a
soundsystem,it is not necessarilythebest
choice for recording specific instruments.
