Description
Earthworks P30/C is a directional prepolari-
zed condenser High Definition Microphone™
with a first-order cardioid pickup pattern
directly coupled to a dedicated wideband, low
output impedance transformerless preamplifier.
The P30/C requires a standard 48V Phantom
Power supply. It features a flat 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 excellent
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/C is protected by US Patent No.
6,091,829.
Applications
Earthworks P30/C is easy to operate.
Connect the microphone to a microphone
preamplifier supplying 48V phantom power
using a standard XLR microphone cable.
Please
allow up to one minute for the microphone to settle.
Plugging in the microphone “hot” (phantom
power already present at the input) will not
damage the microphone, and is actually
preferred 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
power is first applied.
The excellent performance characteristics of
the P30/C give it a very wide range of
application possibilities. With its 4-inch flexible
neck and small microphone head, this high-
quality microphone could be placed where other
microphones could not, such as under the
strings of an acoustic bass. The P30/C is an
ideal choice for recording or live sound
applications using percussion, acoustic or
amplified instruments,
or choir when using
microphone stands. It is superior for choir
because it doesn’t spotlight; rather, it picks up
an entire section with no hot spots.
This microphone has no removable parts.
Care of Microphones
Earthworks P30/C microphone is a
precision instrument designed and built to
provide years of excellent performance.
Following these simple rules will help to protect
your investment in the P30/C:
·
Avoid touching the front protective screen.
·
Never
attempt
to disassemble
the
microphone – it cannot be opened.
·
Avoid extreme heat and condensing
humidity. Allow the microphone to warm up
in the case when bringing it in from the cold
weather. Rough handling may damage the
microphone even if no visible marks are left.
·
When not in use keep the P30/C in its case.
