Description
The Earthworks QTC40 is an omnidirectional (pressure)
pre-polarized condenser microphone directly coupled to
a dedicated wideband, low output impedance preampli-
er. The QTC40 requires a standard 24-48V phantom
power supply. It features an extended linear free-eld
frequency response from 3Hz to 40kHz, extremely fast
impulse response, low self-noise, very low handling
noise, uniform polar pattern, and high SPL handling ca-
pabilities. It exhibits no proximity effect.
Each microphone is delivered with its own calibration
chart providing the individually measured frequency re-
sponse curve. A mounting clip is included with the mi-
crophone.
Applications
The Earthworks QTC40 is easy to operate. Connect the
microphone to a microphone preamplier supplying 24-
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 QTC40 is a premium microphone designed for re-
cording quieter sources such as vocals, strings, wood-
winds, and distant-miked orchestras or choirs. For
classical location recording a matched pair will provide
spectacular results. The QTC40 will faithfully repro-
duce sound with impeccable detail and does not ex-
hibit the typical problems and limitation exhibited with
conventional microphones. Its impulse response and
diaphragm settling time is extraordinary, resulting in the
most pure and uncolored sound.
This microphone has no removable parts.
Care of Microphone
The Earthworks QTC40 High Denition Microphone
™ is a
precision instrument designed and built to provide years
of top performance. Following these simple rules will
help to protect your investment in the QTC40:
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 QTC50 in its case.
