Earthworks SR30 MP Prepolarized Condenser Microphones, Matched Pair



The Earthworks SR30 MP is the matched pair set of the popular SR30 microphone.

The Earthworks SR30 (same as SR77) is a remarkable cardioid that maintains most of the characteristics of Earthworks’ omni microphones. At 6 inches away from the source it sounds as onmi-like as a cardioid can. The off-axis rejection is substantial yet uncoloured. Its impulse response is very fast and smooth and the sound stays the same across the entire front hemisphere of pickup. In the studio or on the stage, theSR30 is an ideal choice for a variety of acoustic instruments including sax, flute, trumpet, guitar, piano and drums. It is superior for choir because it doesn’t spotlight; rather it picks up an entire section or area with no hot spots.

The Earthworks SR30 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 artist.
