Electronic Calibration files are available for your
individual microphone, should you need to calibrate your specific microphone to your measurement software or system. To obtain an electronic calibration file for your microphone call
603-654-6427, ext 14. You will need to provide
your microphone model and serial number. The
cost is $50 which can be paid with a credit card.
Once purchased, the electronic calibration file

Description Earthworks SR40V is the worlds’ first High
Definition Vocal Microphone™. It is a directional prepolarized condenser microphone with
a first-order cardioid pickup pattern directly
coupled to a dedicated wideband, low output
impedance transformerless preamplifier. The
SR40V requires a standard 48V Phantom Power
supply. It features a flat frequency response from
30Hz to 40kHz (Fig. 2), fast impulse response
(Fig. 3), very low handling noise, very short diaphragm settling time, uniform polar pattern, and
high SPL handling. The SR40V provides excellent uncolored rejection of sounds arriving offaxis.
Each SR40V microphone is delivered with its
own calibration chart providing its individually
measured frequency response curve. A mounting clip is included with the microphone. The
SR40V is protected by US Patent No. 6,091,829.
Applications Earthworks SR40V is easy to operate. Just 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
cause a “pop” in the audio or recording system
when plugged in or powered up. Make sure to
mute the signal to speakers or headphones when
phantom power is first applied to the microphone.
The excellent performance characteristics 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 is very popular among a number of major performing artists due to its pristine

sound quality while providing more gain before
feedback. The SR40V is also excellent in rejecting sounds from the rear of the microphone.
Care of Microphones The Earthworks SR40V 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 SR40V:
s .EVER ATTEMPT TO DISASSEMBLE THE MICROPHONE
– it cannot be opened.
s !VOID EXTREME HEAT AND CONDENSING HUMIDITY
Allow the microphone to warm up to room temperature when bringing it inside from the cold
weather. Rough handling may also damage the
microphone even if no visible marks are left.
