Description
Earthworks P30/HCis adirectional
prepolari-zed condenser High Definition
Microphone™ withafirst-order hypercardioid
pickup patterndirectly coupled to adedicated
wideband, low output impedance
transformerless preamplifier. The P30/HC
requires astandard 48V Phantom Power supply.
It features aflat frequency response from 30Hz
to 30kHz (Fig. 2), fast impulse response (Fig. 3),
very low handling noise, uniform polar pattern,
and high SPL handling capabilities. It provides
uncolored rejection of sounds arriving off-axis.
Each microphone is delivered with its own
calibration chart providing the individually
measured frequency response curve.A
mounting clip is included with the microphone.
The P30/HC is protected by US Patent No.
6,091,829.
Applications
Earthworks P30/HCis easy to operate.
Connect themicrophone to amicrophone
preamplifier supplying 48V phantom power
using astandard XLR microphone cable. Please
allow up tooneminutefor the microphoneto settle.
Plugging in the microphone “hot” (phantom
power already present atthe input) will not
damage the microphone, and is actually
preferred for faster settling.It is normalfor any
phantom powered mic to“pop” when plugged
in or powered up. Make sure to mute the signal
to speakers orheadphones when phantom
power is first applied.
The excellentperformance characteristics of
the P30/HC give it avery wide range of
application possibilities. With its 4-inch flexible
neck and small microphone head, this high-
quality microphonecould be placed where other
microphones could not,such as under the
strings of anacousticbass.The P30/HC isan
ideal choice for recording or live sound
applications using percussion, acoustic or
amplified instruments, orchoir. The P30/HC
makes anexcellentspot mic, combiningopen
clarity with uncolored rejection.
This microphone has no removable parts.
CareofMicrophones
Earthworks P30/HC microphone is a
precision instrument designed and built to
provide years of excellent performance.
Following thesesimplerules will helpto protect
your investment in the P30/HC:
· 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 keeptheP30/HC in its
case.
