Earthworks cardioid microphones have patented near-perfect cardioid patterns. The sound across the entire front hemisphere is remarkably uniform and is flatter at 90 degrees than most microphones are on-axis. The SR Series have an incredible transparent sound quality, offering near-perfect polar response and high rejection of sounds at the rear of the microphone, resulting in less leakage and more gain before feedback.Features:The SR30 is our premium cardioid that maintains most of the characteristics of our omni microphonesThe off-axis rejection is substantial yet uncoloredIts impulse response is very fast and smooth and the sound stays the same across the entire front hemisphere of pickupIdeal choice for a variety of acoustic instruments including sax, flute, trumpet, guitar, piano and drumsSuperior for choir because it doesn't spotlight, rather it picks up an entire section or area with no hot spotsPopular 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 artistEffortlessly handle up to 145dB SPL while simultaneously revealing subtle details that other microphones maskProvides excellent results for both live performance and recording application
