Description
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 SR40V in its case.

SR40V
The Earthworks SR40V is a directional pre-polarized
condenser microphone with a rst-order hypercardioid
pickup pattern directly coupled to a dedicated
wide band, low output impedance transformerless
preamplier. The SR40V requires standard 24-48V
Phantom Power. It features a frequency response
from 20Hz to 40kHz, fast impulse response, very low
handling noise, near-perfect polar response, and high SPL handling. The SR40V is
excellent in rejecting sounds at the rear of the microphone and providing more gain
before feedback in live sound applications.
Each SR40V microphone is thoroughly tested and measured to ensure it meets its
exceptional specications. A mounting clip is included with the microphone.
Applications
The Earthworks SR40V 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 cause a “pop” in the audio or recording system when initially plugged in or powering
up. Make sure to mute the signal to speakers or headphones when phantom power is
rst applied to the microphone.
The excellent performance of the SR40V make it an exceptional vocal microphone in the
studio or on the stage, and is an ideal choice for vocals, voice-overs and instrumental
applications. The SR40V’s extended frequency response, fast impulse response
and short diaphragm settling time allow it to capture explosive performances while
preserving the subtle nuances of artistic expression. It is excellent in rejecting sounds
from the rear of the microphone and providing more gain before feedback in live sound
applications.
