TC25 Omnidirectional Microphone
Owner’s Manual

Description
Earthworks TC25 is an omnidirectional
(pressure) prepolarized condenser microphone
directly coupled to a dedicated wideband, low
output impedance preamplifier. The TC25
requires a standard 48V phantom power supply.
It features a linear free-field frequency response
from 9Hz to 25kHz (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.
Applications
Earthworks TC25 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 TC25 is designed specifically for
drums and percussion and is the model that
comes in the Earthworks Drumkit™ System.
The TC25 has a brilliance that is ideal for
drum overheads, percussion, Leslie, guitar and
bass. It is a versatile microphone 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 Microphones
Earthworks TC25 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
TC25:
• 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 TC25 in its case
