Frequency Response of QTC30 (typical)
Description
The Earthworks QTC30 is an omnidirectional (pressure)
pre-polarized condenser microphone directly coupled to a
dedicated wideband, low output impedance preamplier.
The QTC30 requires a standard 24-48V phantom power
supply. It features an extended linear free-eld frequency
response from 3Hz to 30kHz, extremely fast impulse re-
sponse, low self-noise, very low handling noise, uniform
polar pattern, and high SPL handling capabilities. It exhibits
no proximity effect.
Each microphone is delivered with its own calibration chart
providing the individually measured frequency response
curve. A mounting clip is included with the microphone.
Applications
The Earthworks QTC30 is easy to operate. Connect the mi-
crophone to a microphone preamplier 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 pow-
ered up. Make sure to mute the signal to speakers or head-
phones when phantom power is rst applied.
The QTC30 is designed for recording quieter sources such
as vocals, strings, woodwinds, and distant-miked orches-
tras or choirs. The QTC30 will faithfully reproduce sound
with impeccable detail and does not exhibit the typical
problems and limitation exhibited with conventional mi-
crophones. Its fast impulse response and diaphragm set-
tling time results in very natural and uncolored sound. The
QTC30 is also an excellent room mic for ambiance in the
studio and for recording rehearsals and performances. This
microphone has no removable parts.
Care of Microphone
Earthworks QTC30 microphone is a precision instrument
designed and built to provide years of top performance.
Following these simple rules will help to protect your invest-
ment in the QTC30:
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 QTC30 in its case.
