Frequency Response of TC20 (typical)
Description
The Earthworks TC20 is an omnidirectional (pressure)
pre-polarized condenser microphone directly coupled to
a dedicated wideband, low output impedance preampli-
er. The TC20 requires a standard 48V phantom power
supply. It features a linear free-eld frequency response
from 10Hz to 20kHz, fast impulse response, very low
handling noise, uniform polar pattern, and very high SPL
handling capabilities. It exhibits no proximity effect.
Applications
The Earthworks TC20 is easy to operate. Connect the
microphone to a microphone preamplier 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 rst
applied.
The TC20 is our least expensive general-purpose omni. It
is a good choice for close-miking louder sources such as
instrument amps, drums, or close-miked brass. It is also
very popular for drum overheads. A pair of TC20s con-
nected to a stereo recorder will provide excellent results
for recording rehearsals and performances. The TC20 is
great for general studio use and is an exceptional value.
It has no handling noise, no proximity effect, and is very
forgiving in terms of placement.
A mounting clip is included with the microphone. This
microphone has no removable parts.
Care of Microphone
The Earthworks TC20 microphone is a precision instru-
ment designed and built to provide years of excellent
performance. Following these simple rules will help to
protect your investment in the TC20:
TC20
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 TC20 in its case.
