P30 OmnidirectionalMicrophone
Owner’s Manual

Description
Earthworks P30 isan omnidirectional
(pressure) prepolarized condenser High
Definition Microphone™directly coupled to a
dedicated wideband, lowoutput impedance
preamplifier. The P30 requires astandard 48V
phantom powersupply. It features an extended
linear free-field frequency response from 6Hz to
30kHz (Fig. 2), extremely fast impulse response
(Fig. 3), low self-noise, verylow handling noise,
uniform polar pattern, andhigh SPL handling
capabilities. It exhibits no proximity effect.
Each microphone is delivered with its own
calibration chart providing the individually
measured frequency response curve.A
mounting clip is included with the microphone.
Applications
Earthworks P30 iseasyto operate. Connect
the microphone to amicrophone preamplifier
supplying 48V phantompower using astandard
XLR microphonecable. Please allow upto one
minute for the microphone to settle. Plugging in the
microphone “hot”(phantom power already
present at theinput)will not damagethe
microphone, and is actuallypreferred for faster
settling. It is normal for any phantom powered
mic to “pop” when plugged in or powered up.
Make sure to mute the signal to speakers or
headphones when phantom poweris first
applied.
The excellentperformance characteristics of
the P30 give it avery wide range of application
possibilities. Withits 4-inch flexible neck and
small microphone head,this high-quality
microphone couldbe placed where other
microphones could not,such as under the
strings of anacoustic bass. The P30/Cis an
ideal choicefor recordingapplicationssuchas
drum overheads, percussion, piano, acoustic or
amplified instruments. TheP30 is an excellent
room mic forambianceinthe studioand for
recording rehearsals and performances.
This microphone has no removable parts.
CareofMicrophones
Earthworks P30 microphone is aprecision
instrument designed andbuilt to provide years
of excellent performance. Following these
simple rules will help to protect your investment
in the P30:
· Avoid touching the front protective screen.
· Never attempt to disassemble the
microphone – it cannot be opened.
· Avoid extreme heatand condensing
humidity. Allow the microphone to warm up
in the case when bringing it in from the cold
weather. Roughhandling may damage the
microphone even if no visible marks are left.
· When not in use keep the P30 in its case
