Description
Earthworks TC30 is an omnidirectional
(pressure) prepolarized condenser microphone
directly coupled to a dedicated wideband, low
output impedance preamplifier. The TC30
requires a standard 48V phantom power supply.
It features a linear free-field frequency response
from 9Hz to 30kHz (Fig. 2), fast impulse
response (Fig. 3), very low handling noise, uni-
form polar pattern, and very high SPL handling
capabilities. It exhibits no proximity effect.
Each microphone is delivered with its own
calibration chart providing the individually
measured
frequency
response
mounting clip is included with the microphone.
Applications
Earthworks TC30 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 TC30 is an excellent general-purpose
omni. It is an ideal choice for close-miking
louder sources like guitar, bass, piano, horns,
and percussion. The TC30 is very popular for
drum overheads. It is incredibly clean and
distortion-free up to 150dB SPL while
simultaneously capturing subtle details. Its fast,
clean impulse performance yields remarkably
transparent sound. The TC30 is an excellent
room mic for ambiance in the studio and for
recording rehearsals and performances. It has
no handling noise, no proximity effect, and is
very forgiving in terms of placement.
This microphone has no removable parts.
Care of Microphones

microphone even if no visible marks are left.
• When not in use keep the TC30 in its case
