TC30
Description
The Earthworks TC30 is an omnidirectional (pressure) pre-polarized condenser microphone directly coupled to a dedicated wideband, low output impedance pream-
plier. The TC30 requires a standard 24-48V phantom power supply. It features a linear free-eld frequency re-
sponse from 9Hz to 30kHz, fast impulse response, very low handling noise, uniform 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 curve. A mounting clip is included with the mi­crophone.
Applications
The Earthworks TC30 is easy to operate. Connect the
microphone to a microphone preamplier supplying 24­48V 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 TC30 is an excellent general-purpose omni mi­crophone. 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 response 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 Microphone

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 TC30 in its case.
