Milford, NH – February 2, 2011 – Earthworks, Inc., the world’s only manufacturer of High Definition Microphones™ for recording, live sound, and test/measurement applications, proudly introduces the SR40V High Definition™ Vocal Microphone. Featuring revolutionary circuitry for exemplary sonic performance and build quality that is the envy of the industry, the new SR40V gives new definition to the assumptions and expectations associated with vocal microphones.

Featuring a 9 mm back electret condenser-type transducer with a diaphragm measuring 5 microns, the new Earthworks SR40V is an engineering marvel that provides the fastest transient response of any vocal microphone on the market. Combined with a textbook perfect Hyper Cardioid polar pattern, this exceptional new microphone delivers superior sounding, natural on- and off-axis performance compared to any microphone previously available. With a frequency range spanning from 30 Hz – 40 kHz, the SR40V is the world’s first High Definition condenser vocal microphone. The end result is a natural clarity of sound with greater presence and depth than is customarily associated with vocal microphones.
Earthworks prides itself on delivering sound quality as close as physically possible to the original live source. Capturing this True Live Sound™ (TLS) is precisely what differentiates an Earthworks microphone from the competition. The SR40V’s patented technology provides extreme accuracy in the time domain, which is essential for harmonics to be reproduced faithfully and not be smeared or distorted. The new SR40V achieves the re-creation of the True Live Sound with its revolutionary circuitry by combining flat, extended frequency response with lightning fast impulse response. This circuitry is handcrafted to match each capsule for optimum performance and is precisely what makes the SR40V—and all Earthworks High Definition microphones—so unique.
With a self-noise rating of just 22 dB SPL (A weighted), a sensitivity rating of 10 mV/Pa (-40 dBV/Pa), and a Peak Acoustic Output rating of 145 dB SPL, the new SR40V combines extremely low handling noise with robust performance and output capability that enables vocal performers to have the natural sounding, up-front presence they’ve always wanted.
The SR40V’s build quality is every bit as impressive as its performance attributes. Each microphone is handmade in the USA and features a rugged stainless steel body that feels great in the hand—thanks in no small part to its unique blend of balance and precision machining. From end to end, the SR40V delivers industry leading reliability that is second to none.
Bill Norton, Earthworks’ COO, commented on the company’s new SR40V High Definition Vocal Microphone. “We are extremely proud of this new mic,” states Norton. “Earthworks’ dedication to producing what we call True Live Sound has long been a hallmark that defines our entire product line. For quite some time now, music and audio professionals have asked us for a vocal microphone with these characteristics and the SR40V is the result of that endeavor. Everything about this microphone—from its accuracy of sound and the way it feels in the hand to its refined build quality—unite to form a world-class experience that better enables vocalists to showcase their talents in an entirely new light.”
The new Earthworks SR40V High Definition Vocal Microphone is expected to be available Q1, 2011. Pricing has not yet been determined.

Hi Bo. I got the frequency response, polar pattern and impulse responses up, as well as the spec table. To the best of my knowledge, the 30Hz-40kHz is correct. However, I will quadruple check and let you know for sure and update the website to reflect the correct info. Sorry about the confusion and thanks for spotting that!
We did change the SR40V to all black. As of now, there is only the one color option. However, I will bring this up with production and see if in the future we’ll be able to offer multiple color options. But for the foreseeable future it will most likely only be available in black. If you’d like to contact our sales dept., you may be able to purchase one of our original prototypes with the silver/grey coloring if there are any still kicking around the factory. The email is sales@earthworksaudio.com. Hope this helps!
SR40V – specs…?
The advert in the recent FOH specificed a frequency response of 30Hz to 40kHz, but your own website specifies 80Hz to 40kHz – which is it? Or, are there different measurement parameters being quoted…?
Can we see a frequency response curve and polar diagrams, please?
Thanks!

Hi,
In your earlier photos the SR40V was grey with a silver grille, but now it is black…?
Are there two different colour versions of SR40V available? (black or silver) as is the case with many other pro condenser mics, eg. Neumann KMS105, Shure KSM9, Beyer TGX930, etc.
I far prefer the silver colour. Is that still avilable as an option, or special order…?
Best regards,
Richard
Hello,
I am interested in T/E on a pair of these mics for my group, as well as purchasing a pair.
Thank you.
Andrew.
