Earthworks SR40 Cardioid Condenser Microphone



The Earthworks SR40 40kHz High Definition Microphone offers an extended high frequency response, extremely fast impulse response, short diaphragm settling time, exceptional cardioid polar pattern, and high rejection of sounds from the rear of the microphone.

The Earthworks SR40 is intended for a wide range of applications, ranging from drum overheads to miking a guitar cabinet, or as a solo microphone.

The excellent performance characteristics of the SR40 allow it to be utilized for a very wide range of applications. In the studio or on the stage the SR40 is an ideal choice for a variety of instruments including sax, flute, trumpet, guitar, piano, and percussion.

It is superior for vocals or choir because it doesn’t spotlight. Rather, it uniformly picks up an entire section. The SR40 is popular among concert tapers because of its open uncoloured sound and among jazz enthusiasts for its ability to capture explosive performances while retaining the subtle nuances of artistic expression.

The SR40 offers a 30Hz – 40kHz frequency response, revealing subtleties in the sound that are non-existent from microphones with less high frequency range, and enabling musical performances to exhibit greater depth and realism. Equally significant, the SR40 offers an extremely fast impulse response that enables the microphone to acquire fast transients far more accurately.
