The SR40V’s patented technology promises extreme accuracy in the time domain, which is essential for harmonics to be reproduced faithfully, without smearing or distortion. The SR40V’s circuitry is said to re-create Earthworks’ True Live Sound with its by combining a flat, extended frequency response with a fast impulse response. Its circuitry is handcrafted to match each capsule for optimum performance.

Earthworks states that the SR40V has a self-noise rating of 22dB SPL (A weighted), a sensitivity rating of 10 mV/Pa (-40 dBV/Pa), and a Peak Acoustic Output rating of 145 dB SPL. Earthworks designed the new SR40V to combine extremely low handling noise with robust performance and output capability that is specially tailored to vocal performance.

Each microphone is handmade in the U.S. and features a rugged stainless steel body.

Earthworks expects to ship the SR40V High Definition Vocal Microphone in Q1, 2011. For more information, visit
