Earthworks SR30 Condenser Microphone



The SR30 is a remarkable cardioid that maintains most of the characteristics of our 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, the SR30 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 SR30 is popular among concert tapers because of its open uncolored sound and among jazz enthusiasts for its ability to capture explosive performances while retaining the subtle nuances of artist.
